Got the exact same exhaust set-up as this on my MS3. Had to get some warranty work done so it's had the factory exhaust for about a month now. I miss the NOISE!!!

[bdbl0]

What part of Pa you guys from.. NEPA here. also if he is selling it and hasnt sold it yet. Does he wanna get rid of the factory BPV

[mattistheman940]

omg sounds just like a boxer engine i love it

[FenixTX717]

With having the TurboXS downpipe/racepipe did it throw a check engine light or did you guys use a o2 spacer/fouler?

Also is it needed to have a tune for doing a full exhaust system on a MS3 or can I get by without a tune for away?

[specialjoe405]

Any other mods or just exhaust?

[JSCSpeed]

@specialjoe405 At the time it was just the exhaust. Car had a Cobb FMIC, intake and Accessport on it for a while, plus an HKS SSQV, but is now mostly stock again....

[dixie7894561]

how did it run without the cobb ap? i'm doing pretty much the same set up, but i don't have the ap. will i really need it? and why did you stock it out? were you having problems with the car being modded?

[JSCSpeed]

@dixie7894561 You really need something to tune it with...if not the AP then something else...with the FMIC and the AP the car was still super rich...can't imagine it would run well at all on a stock map.

It went back to stock because the car owner is selling it.

[smoogs12]

@JSCSpeed question...when you were running the AP tune with the FMIC and the intake, did you have any problems with fuel cut. gonna be picking up a speed 3 and from what i have been reading everyone seems to say that going with a new HPFP is pretty essential.

[boostedmazda3]

@smoogs12 yes i have cobb AP and FMIC and I was having fuel cut issues at WOT....ordered autotech fuel pump internals.

[mzvarik]

only two rounds? and rip those tires on the corners next time, yeah... =)
