Probably going to have to get a shop to do it. It went in about half way and jammed then tore coming out. I'm just defeated right now. Debating if I need to spend 700 on a new exhaust.Yup been there when I went from quiet to competition baffles it was a challenge. I ended up using a 2” brass wire wheel and I have a flexible extension that is 12” long for my drill a few passes then I fired it up to blow out the carbon deposits, and the new baffles fit in tightly perfect. Never looked back!
