Thinking adding one of these, just in front of the rear muffer (and after the catted midpipes with resonator) on my 1M. Would run it open on the track.

Iam fbo plus meth, so 420 awhp should be pretty easy to get. and i was going to go to brentuning in mass to get it done since his xi put down 440 on fbo and meth. But my sponsor shop has a guy i was told so I'm about to have them do it and save a drive to mass

when i put my stock midpipe on with the secondary cats , while leaving the m2 rear section in place i noticed a drop in power for sure but the clean, quite. odor free exhaust of the car with downpipes and the mufflers with just secondarys in place far outweighs the smell, increased volume/drone, and 10-15hp more..
Weight diff is def a plus as well though with a full aftermarket system
