I'm interested in installing a high flow cat, but most downpipes with them pre installed seem to be around $500. My question is: is it possible to just get a muffler shop to weld in a high flow cat onto a catless downpipe or could i swap my existing cat for a high flow? I don't know if either of these options are even plausible but i wanted to ask. If this would be possible, which option would be least expensive and produce best results?
Thanks
