I got a question for when i smog i have an slp lm1 cat back exhaust will that pass smog? Or should i swap the mufflers only and put my flows? Any input would b great gotta smog before 4-10-09. I gotta take off my o/r h pipes...
I've never once heard of a catback being the reason for failing a smog test. An aftermarket midpipe will get you failed at most test centers.
I went to this hole in the wall place in Elk Grove. I figured they would want the money so they would care more. I passed fine with tune, eaton, Mafia, stuff like that.
