Introducing the APR Catback Exhaust System for the Audi C8 RS6 and RS7

The APR Catback Exhaust System for the Audi C8 RS6 and RS7 is a complete, high-performance exhaust solution that runs the entire length of the vehicle from the catalyst back. This system is engineered to boost performance, elevate sound, and enhance aesthetics with RS-style diamond black oval exhaust tips that are sure to make a statement. Crafted from premium materials and built with advanced manufacturing techniques, this system is designed to withstand harsh conditions and deliver lasting performance. Expect a bold, aggressive growl at wide-open throttle, along with an impressive gain of 9 horsepower and 16 FT-LBS of torque to all four wheels!

Unmatched Design and Precision Engineering  

The APR system includes downpipes extending to the factory catalyst in the upper engine bay, making this a true full-system upgrade. We’ve minimized restrictions with smooth transitions, cast inlets, oversized piping, and straight-through mufflers and resonators. Constructed from mandrel-bent T304 stainless steel with a brushed finish and TIG welding throughout, this exhaust system is as durable as it is striking. Installation is hassle-free, thanks to precision-fit brackets and OEM-style slip clamps.

RS Performance  

The entire system is increased to a dual 3” (72mm) exhaust path. With the exhaust valves open, the exhaust gasses travel uninterrupted from the front of the system out through the exhaust tips. When exhaust gasses travel into the multichambered rear muffler / resonator, they continue uninterrupted and a Helmholtz resonator reduces drone frequencies without restricting flow on the open-valve path. With the valves closed, exhaust gasses travel through a sound reduction path via a smaller 2.5” (63.5mm) pipe, reducing volume and allowing the system to act more civilized when needed. Finally the system terminates via oversized 8.23”x4.76” (211x21mm) RS-style oval exhaust tips. The tips feature a diamond black finish and a subtle APR logo for a refined touch.

Beautiful Panties for and Excellent Value
These are beautiful panties for the price! I truly love their packaging. As they make one feel beautiful and it is very inclusive. They were arrive in an hygienic plastic packaging within a colorful envelope. All of the underwear are shaped in bikini style, and they also have a beautiful lace trim all around. I really like the warm colors of this pack that I chose and I also enjoy the beautiful feel and look of the lace they are made out of. Really good quality and I love how breathable and comfortable the cotton is. Depending on what one is wearing these cotton underwear may be somewhat seamless under clothes. They fit really well and they are super comfortable on. I really like the quality of these and the value. I really enjoy the undergarments from this brand. I recommend!

Soft, stretchy, comfortable!
As a CIS male, I made the switch to women's panties years ago... they just fit better, don't ride up anywhere, and hold the 'boys' better. These panties are no exception. Being a larger man physically, I usually order panties in the XXL to 3X range. These XXL just fit. They are made from 95% Cotton and 5% Elastane, which I have come to prefer (the elastane) in underwear as they help regulate temperature. The lace is not bothersome at all, and the back side show your butt like a pair of cheekies, but give plenty of coverage. The colors are different from what I normally wear, but I'll take comfort over fashion anyday, especially when dealing with down there. The fabric is soft and stretchy, and I was able to wear these all day without having to adjust much at all. Nice panties for this man!

Great quality!
My wife loves these panties. She says they fit great, they are very soft and comfortable, and best of all they hold up very well when machine washing and drying. Now that she's put them to the test, I just ordered her more.
