I'm redoing the exhaust on my truck and will be doing a 2.5" wye into a single 3" or 3.5" exhaust with a single cat. I'm gonna stick a high flow cat on there,however,I need to pass a tailpipe test for emissions so need a cat that's functional as well as high flow.
Which kinda cats are you guys running that have proven themselves in a tailpipe test?
