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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eINVIDIA PERFORMANCE\u003c\/p\u003e\n\u003cp\u003eFar 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.\u003c\/p\u003e\n\u003cp\u003eInvidia 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.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eINVIDIA SOUND\u003c\/p\u003e\n\u003cp\u003eWhat 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.\u003c\/p\u003e\n\u003cp\u003eTuning 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.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eINVIDIA CONSTRUCTION\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eFirst, 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.\u003c\/p\u003e\n\u003cp\u003eFinally, 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.

It is cast in high temperature ductile iron which ensures optimum internal shape and maximum durability under high rpm, load and boost conditions.

The reason for the 5” body is that it flows better than the 4” body when flowing both with comparable cells. The bigger the area within reason the more flow it will have. You might ask why 160 cell and not 100 cell like some of the aftermarket front pipes available on the market, we know that it will help with the maintenance of emissions control.
