Just curious. I was searching Ebay for cat-backs and mid-pipes and I found this one company Total Peformance sells MAC Cat-backs /3'' SS tips for $300 (cheapest I've found anywhere) and the prochamber for $210 (Also cheapest anywhere). However I noticed that the systems were not the usual HTS coating or whatever (basically not gray) but they looked like a shiny black. Has anyone ever bought one of these from these guys off of ebay? They said that they coated the exhaust and prochamber to prevent rust. I'm thinking of buying from them but I would like to know your feedback on this company. Thanks.
