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?

Good for non chewers
Color: Large size (ø 7.4")
Dog lived it for the 4 minutes before he chewed a large hole in it. Definitely not for heavy chewers.

This is actually a fantastic dog toy!
Color: Large size (ø 7.4")
I originally got this for my golden retriever. He loves all things ball-shaped and I figured the handles would make this really easy for him to carry and for me to tug. It was a fantastic hit not only with the retriever but my lab and even my older Great Dane also love this toy. It's about the size of a soccer ball and covered in a nice rubber that can be chewed off if you have a destructive player but is more than durable enough for tossing around the house or even in the yard. Chewability-wise, The Dane managed to chew a couple of chunks off the handle part but he's probably a pretty extreme example. I think this would hold up just fine for most dogs' play. I just have to supervise it with my Dane so that he doesn't chew it into a pile of rubber. The biggest surprise of this ball was the fact that it has one of those slide whistles in it that makes a noise as it tumbles and rolls around. This proved irresistible to the Golden Retriever and the Lab. Every time they hear the slide whistle inside, they get up from wherever they are and focus 100% on this ball. It has some heft to it and it bounces a little but not as much as a regular ball its size, it's fun for the little ones to play with inside but it's primarily an outdoor dog toy. The handles are big enough for a human hand to hold them comfortably. It rolls in a hard-to-predict way that is extra helpful for the smaller dogs to chase.

Aggressive chewers have met their match.
Size: 10.5 inch Rubber Flex Tread
We purchased this toy in 2022, it finally broke last night. Four years of rough play with 2 boxers who are aggressive chewers. They would tug together, gnaw on it for hours, and often leave it outside exposed to the elements, but this toy just kept going. It was by far their favorite toy, it kept them busy for hours. I just ordered a replacement. Well worth the money, perfect size. Highly recommend.
