I got some new headers (borla reps) fitted them in today and used the gaskets that come with them, noticed that when i revved there was quite a noticeable raspy noise, on idle it sounds perfect though.

Could the reason be because i used the gaskets that came with the headers? The stock ones looked better because of that metal ring in the center of the gasket holes.

Also could it be because I have a cannon diff back 4 inch tip muffler fitted?

Note: I read the other topics and they don't say stuff about a cannon or the gaskets :p
