pulled the cats off and cut in between each cat then took a piece of pipe and a hammer to the insides. Once they were hollow I put all 4 back on. I also have the o2 things to keep the cel off. I am uploading a video now. dunno how good it will sound....
Awesome, i'd love to just gut my back 2 instead of having to take em off. It'd make cops alot less likely to whip out the tickets lol
That is the main reason I did that. They could test the exhaust but then my argument would be I must have bad cats cuz all 4 are on the truck...haha
