hey guys, I changed my tips on my exhaust pipes today. I had 3" by 6" long ss tips removed and had 4" x 12" tips welded on. its a lil deeper and quieter ,don't hear the rap and pop so early any more. it feels like it picked up a lil low end- but I think the butt dyno is wrong. prolly not hearing the roar so soon . what yall think?
