Catback question for stock Z28.
I was looking to get a Magnaflow catback for my Z and I was just wondering if a tune is needed after installing the new catback? And also, do they need to be welded? I know some systems are just bolt-ons.
Sorry for sounding so newbish, but I just want to make sure before I make this purchase.
