I know I have an exhaust leak I can hear it at about 6-7k rpms......I plan on ordering a new exhaust system...If I replace the gasket now will I have to do it again with my new exhaust? Or should I just do it anyways?

 

If you have an exhaust leak, do not reuse the gasket. Depending on where the leak is, it could demolish the gasket very rapidly. They aren't that cheap, just get another one. That or you could just put off replacing the gasket until the new exhaust parts come in, assuming that will be pretty quick at least.

 

Yeah, where is the leak?

If you have an exhaust leak it will show up when you inspect the gasket.

Its rather obvious when you see it.
