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?

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

It’s ridiculous…
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
When I got these pillows I was a little disappointed that they appeared to be a little lumpy. I fluffed and let them rest for a couple of days to see if they’d poof up. Finally figured this was as good as they were going to get. First night sleeping with them…my life has changed! I typically like a lot of pillows. I’m usually a restless sleeper. I fell asleep quickly and slept through the night for the first time since I can remember. No aches and pains as usual. It’s ridiculous that a couple of pillows could have made such a difference in my quality of sleep. Who knew?! I’ll buy these for every bed in the house.
