macht schnell x pipe Rasp delete

m3boost · 10-08-2021, 06:04 PM

Looking to remove the raspy tone of the macht schnell x pipe. Currently have it paired with ipe f1.

Thinking I might just need to sell it and grab something with hfc.

Or I can add 2 high flow cats.

Any tips would be appreciated.

Thanks!

Get the BW race pipe. Throw on two vibrant resonators and 2 HFCs.

Just buy a couple of 200 cell cats and have them welded in the secondary position. No sense starting all over for what Is arguably the same thing. Check out Vibrant Performance

Can you pass smog with 200 cats?

Maybe - Depends where you live. Didn't see smog as a requirement in your post. Get an oem xpipe.

Have the oem already and been swapping for 5 years for smog. Would love if 200cel worked lol

Depends on the state. Put the 200cels in and give it a whirl. If you fail, swap back to oem. If they OBD then you'll likely fail with the downstream O2s disabled.

The quad resonated x-pipes I've heard (Bimmerworld or Borla) sound amazing (no rasp).

Im wondering if the actual x portion of the stock x-pipe restrictive at all?

Are the stock resonators restrictive at all? Or are they straight through with perforated/resonated inner walls?

I have zero rasp with my macht schnell x-pipe but I'm running borla s-type mufflers.
