I bent a few al catback pipe only pieces but it wasnt cost effective for me to make an obscene profit so I quit lol. Looked like this but this one is one i did in stainless. I have a 3 inch bent up now that im going to test fit this week hopefully.
I currently have a 2.5 mandrel al catback on my car with round magnaflow in front and jones maxflow in the rear. Sounds good I made the al pipe kits for a while but didnt make an obscene profit so I quit lol. Heres one I made in stainless for a dual out option.
