Technically it is ILLEGAL to modify emisions control systems in any way. Have fun failing visual inspection!
Funny you'll support a country club (expensive) race track and justify the cost of membership, yet you won't even spend money on the most elemental power gains on a car (exhaust) and want to have some half ass rigged up exhaust on a BMW.
u cant get power gains from boltons with my car... only way possible is to upgrade the ECU. im not turning my A/T BMW into a race car... i have other plance for that. Yes i plan on taking it to the track... yes i want to have some fun in it. No i do not see myself spending $1000+ to bolton a catback that gives me 4+ hp gains.Originally Posted by green91
The resonators that would be replaced work as SECONDARY cats... no sensors. its legal.... and i'll still pass emissions... do some research.
ohhh it's automatic?! DO NOT put an exhaust on it lol! If anything take off the stock muffler and put a Borla on. Loud exhausts do not belong on automatics outside of sub 10 second drag cars.
lol yeahits an autotragic. i got it as just a DD, fun car to drive. i have had a manual for a LONG time and i figured i would be happier with an automatic for my drive back and forth to work.... i was wrong
