You would think it would be the same as a 4" straight pipe; the restriction was making everything wacky, and parts of DPF were also breaking off.

I read it would stay solid.

Live and learn.

I am now very happy with the RaceME.

120 hp is clean enough and the truck jumps to 110mph empty on the race track.

Excited to go Warp soon and have it better, but as it is now it is 1000x better.
Pleased to hear you fixed the problem.

Special thanks to @Chrisn162001 for picking up on the 3 1/2” hole issue.
