INVIDIA R400 CAT BACK EXHAUST
Invidia's most popular exhaust system.
Specifically designed to fill the sound gap between the Q300 and N1 system, the R400 produces a unique, agressive note while minimising harsh cabin noise (particularly at highway speeds). The R400 muffler was designed using years of experience from Invidia's engineers to allow the perfect balance between unrestricted exhaust gas flow and sound dampening. This exhaust system will provides a pronounced exhaust note throughout the entire RPM band even when only installed as a cat-back system. The R400 muffler design also looks great with a race inspired design that will turn heads.
The Invidia R400 Exhaust takes quality, performance and looks to a new level.
From start to finish the Invidia Exhaust Systems are designed with performance in mind with the exhaust route carefully selected to ensure minimal bends, allowing for an unobstructed exit of exhaust gases with minimal restrictions and turbulence. This will allow for improvements in both horsepower and torque, along with improvements in throttle response with a reduction in turbo lag for turbocharged vehicles. Additionally, you get the reward of an aggressive exhaust note.
INVIDIA 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 larger pipe diameter and smooth bends which 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.
To withstand the high temperatures seen at the turbocharger, laser cut cast steel flanges are used 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. This is a 100% bolt on installation for right-hand drive vehicles with no modifications or changes required. Factory O2 sensor locations are also retained to ensure compatibility with factory systems.
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.
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.
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?
