RE: quick exhaust question
I dont see the giggle gas being bad for your cats ( not like its toxic or anything) as for backpressure , you will lose some, but also pick up a few hp with the O/R pipe so its really a non-issue... also you dont need a new tune for the O/R pipe...but you may get a check engine light
