SAE corrected numbers on a modern turbo engine means comparisons are useless unless it was done on the same dyno and same conditions.

Hopefully it doesn't fall in the same price category as the others

I think with the past track record from BMS you know the answer

Any idea when it will be released?

stranger · 12-21-2015, 03:28 AM

Will you post a video paired with cat less downpipes

Like to ensure that going cat less won't cause the time to become raspy

BMS does not have catless on their car, but I may see if they can send me a unit and I can put it on our M3 which is running the stock exhaust with catless downpipes right now.

Hearing it with catless pipes will be fantastic. Just to clarify, is this an axleback or does it also replace rear cats and/or resonator?

Its a full downpipes back exhaust.. See pic

Boss330 · 12-22-2015, 11:19 AM

That is one of the best sounding aftermarket exhausts I have heard (judging by video quality sound). More bassy and less raspy than the other exhausts out there

Glad you like it.. Probably will have a couple more revisions until FINAL version is ready!

Will keep everybody updated!

ssabripo · 12-23-2015, 08:35 AM

make it come in considerably cheaper than the rape-age prices the others are going for, and provide 90mm and 100mm tip sizes, and put me on the list Mike

yellowssm · 12-23-2015, 08:43 AM

sounds like you guys are gonna have to make a few hundred of these for the first run

Ya seems like demand is pretty high.. Will see once its released but the feedback has been pretty solid so far.

Mike

yellowssm · 12-23-2015, 05:53 PM

Time to make downpipes...
