Exactly what I wanted

Install was a little on the harder side but overall worth it. Is a great small increase in sound for an everyday driver.

About what I expected

If you want your car to be obnoxiously loud this isn’t going to get you there. If you want to change the tone and make it a little deeper, and add a little bit of volume, this is perfect for you. Install is easy as long as your comfortable cutting your exhaust in one place. Minimal drone as well, it’s slightly more noticeable, but not overwhelming or annoying. Overall Sound is more aggressive without being too much. Very cost effective exhaust mod.


Great upgrade over stock resonator

These guys have super fast shipping. I ordered the part on Thursday and got it on Saturday. The pipe itself is exactly what I wanted. Definitely measure twice and cut once. Do not use that "5 1/2" back from the hanger as a mark. I measured it and cut it to fit perfectly. It was about 6" or so back from the hanger. Getting the oem clamp off the front was not easy. We had to cut it off with a reciprocating saw. After that, everything installed easily.


Perfect addition

This is the perfect addition to my exhaust setup. This pairs with the IE downpipe and stock muffler sounds just right to me. It adds a little extra mid-range growl at higher rpms and allows the crackles tune to be more pronounced. With the stock flaps closed I can still be civilized and not sound like a race car.


Great addition for a little more sound

No complaints about three quality of this piece - just as good as the OEM Audi part and less than what some other folks charge for the exact same type of thing. As far as what it does, it adds a little more sound to your R so you can hear your car come alive a bit more. I don't think it's loud at all and don't see any drone or anything else to be worried about. The R is a very quiet car to begin with so if you are looking at this I'm going to assume you want more noise which is what this does.
