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.
