if you get the MAC long tubes, then purchase the ceramic coated tubes....goto
crmotorsports.com.... they have some on sale...it might be cheaper to have someone cut you stock h-pipe instead of buying a new one... it'll probably cost more to have them re-attach the cats back to the pipe, but at least you'll save money on buying a brand new one...i don't know if anyone is ceramic coating MAC's prochamber or not..
I personally think ceramic coating would be the best Idea. However, if you dont feel like going with ceramic coating, then purchase a few cans of Hot engine paint. Its heat resistant and will help resist corrosion. Just slap a coat on, let it set overnight, then install. Keep an eye on the coating. If it starts to flake off, just add another layer and let it set overnight before driving the car again.
