about to give the exhaust a try if it fits the xi

I wonder how much you picked up by ditching the secondaries and opening up the axle back...I'd wager it gets in the 20WHP range if you are pushing 20+PSI. Good stuff for sure

Ya but the HPF exhaust is the holy grail of E9x exhausts. Too sexy i'd run it if it lost me a few WHP lol.

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.

Thought about electric and manual cutouts, but none of them are particularly reliable and/or seal tightly.

~22PSI for now due to some issue not really sure if it is turned past that it spikes to 28+. However yes, I was able to go from ~500WHP(this is just an estimate it just was too restricted) to ~550-580WHP now depending on the days the meth wants to flow correctly .

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

I was considering brentuning as well I wonder if he could get me over 400 awhp full bolt on no meth with 93 oct ?

I got in contact awhile back and he said it would be cutting it close on 93 but it's possible he said .

too bad no E90 system, I have M2 on a WRX ~12yrs ago that sounded great, nice quality piece.

Trust I know lol would have to cut the tips to make it work but that's no big deal .

[ChuckD05]

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
