Thread: ZZP 3" downpipe install help (rusted parts)

I bought a 3" downpipe for my car, and the current flange connection between the cat and the back exhaust is a rusted mess.

Is there a flange I could purchase to match up by simply cutting off the section? I was not looking to completely replacing cat back at this point.....

I was digging on Amazon, and I found a 2.5" flange I could use along with a 2.5" Butt Joint band clamp. Looks like it should do the job.

Thanks for that. I will prob clamp for now, and I was planning on picking up a welder In the near future for misc projects.
