Cat Delete Test Pipes
I was wondering while I had my truck up on the lift in my garage this morning.... has anyone had a set of cat delete test pipes welded up for off-road use? just wondering if the cats are even that restrictive, and if it would do anything besides just sounding better. Any ideas?
