i got a mac longtube ceramic coated headers, mac prochamber with durablack finish and cat back with 3 inch stainless tips for under 1000$

I have the Mac long tube headers on my car with the Mac prochamber and Mac catback. Nice sound. I'm going to convert my mufflers to turn downs though once I get a turn down kit. It should sound even more loud then lol.
As for fitting issues, there were none. The headers bolted right up. The only complaint I have is the Mac pieces tend to rust but this can be avoided somewhat by either having them ceramic coating or prior to install, coat them with a few coats of engine paint and then wrap them with exhuast wrap.
