ATM Muffler delete

Just a quick heads up for those of you running an ATM exhaust. Muffler delete pipes have just been released, including adjustable and removable tips. Will post video of sound with catted dp as well

Don't think so. I sold my cans to a 335i owner and he is having to do some welding to make them fit. Think pipe are diff angle.

Sounds good!

So the pipes just delete the Muffler then?

Seems like a quick easy install!

I’m also interested

I am running ATM turbo back w/ mufflers. and from the video the exhaust doesn't sound too different to me IMO. maybe the OP could chime in if they noticed a significant difference.

I noticed a significant difference. You should note that I am running a ATM catted DP in the video, so sound is very comparable to my set-up with ATM turboback with mufflers and uncattted dp. I lost some sound with the catted dp and this has helped me regain the grunt and whistle.

ATM has the straight pipes on sale currently and I'm on the fence about this or just gutting my SCR as part of my delete.

Anyone else running these pipes, (with a catted dp)? They really don't seem that loud for a straight-pipe set-up.

Sound is about equal to an uncatted DP with mufflers in place.
