New for 2024: Revised design with 300CPSI catalytic converter to suit stricter EPA emissions requirements

INVIDIA CATTED DOWN PIPE

The most restrictive component of the factory exhaust system is the down-pipe which begins right after the turbocharger. Invidia Exhausts use a open bellmouth design to completely open up the exhaust flow path out of the turbocharger. This open bellmouth design combined with a larger pipe diameter and smooth bends allows the turbocharger to exhale exhaust gases with fewer restrictions and turbulence. Because of these reasons, Invidia down-pipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque with a great reduction in turbo lag.

The bellmouth is made from cast 304 Stainless Steel to withstand the high temperatures seen at the turbocharger, with a laser cut cast steel flange to ensure long lasting leak free reliability. A High-Flow catalytic converted is utilised to control emissions for street driving legalities but with minimal impact to exhaust flow. Designed locally to suit Australian Specification Vehicles, this is a 100% bolt on installation for right-hand drive vehicles with no modifications or changes to the steering knuckle required.  Factory O2 sensor locations are also retained to ensure compatibility with factory systems.

 

INVIDIA PERFORMANCE

Far more engineering goes in to the design of an exhaust system than many realise. From a performance perspective, there is a fine balance between exhaust back pressure and exhaust gas velocity. Too large a diameter pipe, and low down power and torque is sacrificed (particularly on naturally aspirated cars), too small a diameter or added restrictions and bottle necks in the system, and the engine is unable to push gasses out of the combustion chamber efficiently, reducing power and torque. There are many other technical aspects such as "scavenging effect" which are beyond the scope of this document, but the point is, it's not as simple as just strap on a drain pipe and gains for days. A "quality" exhaust system maximizes performance gains by design.

Invidia High Performance employ a team of engineers and conduct thorough research and development for every single exhaust component they manufacture, ensuring performance to match the customer's needs in every instance, including the use of the highest quality High Flow Catalytic Converters where applicable.

 

INVIDIA SOUND

What an exhaust sounds like is typically the number one factor when choosing a system. The acoustics of an exhaust system are hugely complex. Many people believe that all an exhaust does is muffle the natural tone of the engine, but in the vast majority of cases this is far from the truth, in fact companies like Ferrari, Lamborghini, Pagani, Porsche and alike all spend massive amounts of time and money "fine tuning" their exhaust systems to sound exactly how they want them to. Put a straight pipe on just about any hypercar and that distinctive engine note is lost.

Tuning the sound of an exhaust system adds an additional layer of complexity to the performance aspect of the design process. The goal is to design a system that sounds great, without adversely affecting performance. Invidia spend countless hours on research and development, including listening to customer feedback in order to fine tune their systems to suit the target market for each model from the quieter Q300 to the Race orientated G5 Titan, so you can be assured your car sounds its absolute best, without sacrificing performance.

 

INVIDIA CONSTRUCTION

The final piece of the puzzle is perhaps the most important of all. you don't have to be an expert to realise that all the research and development in the world means nothing if the final product is built with sub-standard materials, using sub-standard manufacturing techniques. From the very beginning, Invidia employ state of the art manufacturing techniques to ensure form, fit and finish are all on point.

 First, a 3D scan is take of the underside of the car to ensure fitment is 100% correct.  Next, grade 304 Stainless Steel  (with the exception of their titanium systems of course) is selected for all piping, mufflers and flanges. This particular grade is chosen for its strength, durability (ability to withstand the elements),  and its ability to be formed and welded with relative consistency and ease. Cast flanges are then used which ensures 100% correct fitment every time, no leaks or additional stress points, and long lasting strength.    , an

Finally, robotic welding machines are used to ensure every single weld is uniform and precise, not only adding a huge amount of strength, but also removing manufacturing variances which are unavoidable when doing a task by hand. This means every system that rolls off the production line is just about as identical as possible. All built to the same incredible high standard. Did we mention it also looks absolutely awesome?

Great card to have highly recommend
Like using the card for everything. 5 to 7% cashback credit is awesome. No interest is even better. I put almost all my purchases and bills on my credit accounts or credit cards and pay them off monthly. Now that I'm a senior citizen I don't like to go to 20 different stores to find the best prices. The card made my life less busy and I don't have to worry about paying for the many, many things I need right away. Even though I pay off all my accounts every month. If I need a big ticket item, like a new flat-screen television I can get it and not worry about the cost by paying over time if I need to. Having another credit account has also improved my credit score by the hundreds. I was in the 500s for decades until I started the secured card on Amazon. Now I am nearly at an excellent score in the high 700s and don't need secured credit cards. I can use my account at Whole Foods and have my phone scanned for payment. It's just so easy to use

Credit limit drop without cause, Synchrony?
Hey Synchrony, I've about had it with your services, I have 2 cards I use through you through Walgreens and Amazon. You lowered My credit limit on both cards causing me to go over on one because of stupid interest when I had 500 left and I had quit using the damn thing, and my Amazon store card I just Made a 200 Payment on! Lowering my limit and leaving me blind, You should call your customers leave a voicemail or text for heck sake ill read them, I don't read my emails usually for 2 or three weeks, well you did it again, but this time to card I just paid 200$ on too!, Your company sucks, I hate your practices, and I want you to know that. I also want Amazon to know that!! I spend a Boatload of money through amazon, as does my entire family, all ya gotta do is look!! Well I have never felt more unappreciated, insulted, like I stole something or like dirt ever ever in my adult life like you made me feel. Like i'm doing something wrong. Well guess what Synchrony Bank? I'm not doing anything wrong, at all!! I've never been late or missed a payment with my Amazon card or any card I have with you, Synchrony. Your Faceless Corp in its infinite wisdom, decided it would be a great idea to screw over an actual good customer just because some stupid algorithm reported my credit limit was too high and I was a risk, and lowered my limit from where it had been for the last 3 years and then sent a Quiet email about a letter that you put on my online account, please read it, just like that, no Urgent header nothing not that. I don't even read my email that often. I DO read texts or my regular mail, or listen to my phone messages!! I meant what I said NEVER LATE not even once, and NEVER MISSED a payment NOT once!!! The ONLY time I ever had to deal with any kind of problem was the one that lowering my limit on my Mastercard were the cause of, Synchrony!!! when you dropped my credit limit without me knowing and I went over my new dang limit because interest charges were coming in!!! I new where I was and had it handled and would have been able to ride the storm but no you had to mess with my account. Oh and I dont give a Crap if you quote me "we have the right to raise or lower you limit whenever we want", It's a BS excuse to screw over your customers, I know about the terms, however in all of my 54 years, you are the only credit card company that has ever lowered a limit one a CC I had EVER! and I've dealt with some Super sketchy Dirtbag Why did I ever agree to this card, charge me for everything Companies. Mostly when I was young but not even they cut my limit, without me missing payments or being late .....Now 30 years later much older and I thought wiser better CC much better 2500$ limit I've had for years and expect that limit to stay in place or like my Prime Store Card 2000$ limit to stay in place!! not dropped by 500$, for hells sake!!!! Well today I get the old hey your payment option for your try before you buy order needs addressed, and why do you think that was? Hmmm? Well, Ill tell you!! Because you Dropped my limit, by 500$ Now if Amazon dropped it then Ill chew them out too, but I don't think it was them, cuz you did this on my Walgreens card too!!! I just made a 200 payment on my Amazon card as well jerks! Not one of the several companies ive had previous Cards with NOT Cap one Cred one, citi, Community bank, american express, discover you name it, and Ive probably had it at one time or another dozens upon dozens over my adult life at this point anyway. Well, not even the Sleaziest Dirtyiest Gutter Scum CC company with fees for just looking at your card has ever lowered my credit limit not in 34 years Especially when I wasn't late or missing payments ever, always been on time and never missed a payment not 1 time, Except SYNCHRONY, and I think you suck for that!! The only reason I gave 3 stars is Amazon doesn't deserve a 1 star review because of your company! I love amazon, I love their products, their deals their delivery Amazon Prime, im ride or die with Amazon, my kids do all their shopping on amazon they even use it for groceries and stuff occasionally, but I really, really don't like how you treat customers Synchrony, especially customers, that pay on time and even early, oh and on auto pay for Christ sake!!! Now I know why some young dumb kids and people say screw it and stop paying CC bills, cuz the Corporations that pass em out like candy to kids, I might add, are SCUM bags, thats why!! It's all about the GREEN, more, and more and more money its never enough!! Well, when you dropped my credit limit without me knowing and I went over the limit of a different card I had with you, it was because of interest fees coming in. I expected and knew about these fees, however, I also thought I had 500 more than I had available on my card!! What a great day that was, let me tell ya!! I didn't even miss a payment I just didn't make a big enough one to cover the interest that came in, and I also never just pay the minimum payment with these cards either!! Your practices are shady, and the crap you pull against loyal customers that pay on time and even on Autopay are so Scummy!! You know when you dropped my credit limit without me knowing and I went over my limit because of interest, I even reached out to my current lawyer about Bankruptcy choices and stuff and if I should deal with you that way, but I got over bein mad! You know if I was late all the time and a crappy customer missing payments I wouldn't blame you for anything and at least Id know my cards were lowered and probably locked ...but I didn't want to do that, I wanted to try and slide right back into auto pay and get back on track and to deal with a recent Identity theft issue im having and not stop paying my bills OH..yeah, you smellin what i'm sellin? Well because of some terrible thing I must have done in a Past life, I guess. Several months ago now when I was dealing with the death of my mom very suddenly. I also noticed my credit score started dropping and I had no idea why, well turns out i'm MR popular. I had all sorts of crap in my name most of it local where I live and surrounding locally. 100 points in like 5 months!! I digress, Whatever! I don't care anymore, cancel my cards if you want, I'm done! This world is goin to hell in a hand basket, Civil War is almost immanent, a Faceless mob can destroy peoples lives just by canceling them on the internet at a whim. When its true I agree with the mob but when there isn't any proof and someone's life is upturned and then it turns out to be a total lie or they said something 12 years ago and its dug up? Good God, I probably said some haynous stuff when I was 25, but I can assure you when I was 37 I was not that person anymore, my views had changed on many things,,,,that stuff is crazy, and so am I for thinking I can do a damn thing,,,, my mom died 5 months ago, I was just recently laid off from my job I had for 17 years last month, and now you drop my limit again when i've been on time and auto paying and almost screw up my Amazon account!!so screw it!! Eat It Synchrony Bank,Eat It! Sorry about 3 Stars Amazon.

Great fragrance & texture!

I bought this because I loved the spa-like fragrance of the Avene micellar water. This also has a wonderful fragrance and texture, and love the way my skin looks and feels after Inuse it. Thank you for being environmentally conscious and vegan as well.

Super smooth and gentle cleanser
Style: New formula!
I love Avène’s products. This face wash is super gentle and hydrating and I love to use it in the morning to wash my face or at the end of the day when my face feels super dry (otherwise I use the Avène acne cleanser) - it does not leave my skin feel stripped or dehydrated.
