I've been looking instead at anything that will reduce EGT... which ofcourse will help things.... So been looking at the dark side intercooler.... and also this: https://www.kwe-racing.de/Audi/Audi-...ml?language=en
I went with the smog legal Magnaflow catback to stay on the right side of CARB here in Cali myself. I also went with an OEM Audi BITDI intercooler; I'm sure they could still mess with my warranty coverage but I figured it would be less likely if was an OEM audi part.

Pittdawg,

I was looking at the magnaflow catback for mine. Do you see any benefits from it besides sound? Just curious as I considered doing this as well.

Thanks!

I didn't dyno before and after or log egts but I imagine I gained at least a few hp and a slight dip in egts. Other than that, it looks beautiful and adds just a very subtle amount of a deeper tone. If you have all emissions equipment in place the sound increase is very. very subtle but I like the stealth sound.

Solid setup man! I went to a local shop and had them remove both the rear mufflers but I’m keeping the alphabet soup for the mean time. I found several posts showing the inside of our stock mufflers and those are great at restricting the exhaust at the very end.

$200, new pipes welded onto the backend, more responsiveness and can barely hear a difference. Not mad at all, lol.
