i want to put a catless exhaust system on my truck. but the problem is i live in cali and they require cats. i was wondering if they make bolt in inserts for the cat and reg. pipe. so that way all i have to to is after smog unbolt the cats and bolt in a peice of pipe. Any help would be wonderful. i have seen it done on porsche but not anything else. thanks in advance.
