Technically, the fine in CA is $2500 per missing cat...which means $10000 for an offroad midpipe on a 99-04 GT...and I wish I was joking...now of course cops aren;t going tocrawl under your car but could use a mirror. They might just give you a fix it ticket for the sound, but there are roving spot checks by the State to check for modified cars...lame yes, is this gonna change, no.
I heard Bassani X-pipes dont sound all that great with Flowmaster AT. should i spend the $ on a Bassani X-pipe and hope for the best? I dont really have the $ to get a new Catback system 2.
