Yup... No problems for me either... And never will...

 

Mac doesn't use a true 'ceramic' coating...its a version of ceramic. True ceramic coating will not only remain 'clean' for years it will SIGNIFICANTLY reduce underhood temps. I can litterally put my hands on the header just a few minutes after being run. First pic shows 2 yrs of mac coating..second pic shows 2 yrs after true ceramic coating was applied by a coating shop. Expensive..yeah, as much as the headers, but looks, life, power from reduced temps...worth every penny.

 

dman302 where did you find your oil cap?? haha i know this is random but i allways wanted that one and could never find it where did you get it, also im runing mac equel lenght shotys right now with ao/r h-pipe i was thinking of goin to long tubes with a catted h-pipe (cops suck in my area) will i see a difference and will i loose the sound cus seriously thats the best part is hearin it haha

 

Oil cap cam with the FMS valve covers..as for LT...performance gain/loss/sound/ will depend entirely on the setup your running. Heads/intake/cam etc serously affect the tone or sound of the car as well as performance.
