Active Autowerke Headers

Guess I’ll stick to stock sec 1 & 2.

If you want to calm rasp/drone down, you can get a sect 1 with 2 resonators or weld in a resonator into your sect 1. You could also get the Supersprint (or RE or SGT reps) X pipe sect 2 (resonated). it cuts down on rasp and gives a different sound overall.

Does it eliminated the deep burble-ish tone? Cuz that’s what I like.

Just an observation, but one thing I noticed with the AA/Megan headers is that each bend seems to be a joint that's welded together throughout. One of the bends (0 or 6) has 3 pieces welded together at the top. Euro headers have a seamless bend, perhaps mandrel bend?

Megan's are on and boy they're raspy. I'll be looking to pick up a used section 1 and make my own rasp pipe as this guy did.

I thought it was bad and then I basically did a muffler delete with a GruppeM sec 3. The rasp was LOUD. With the CPI it's much better but the rasp actually improved the exhaust sound above 4500 rpm. In traffic I was a rattle can. To avoid other people's ears bleeding, I just took off kinda slow.

I started my car without the section 3 on and it was quieter than the GruppeM.
