EB2 4ltr XR6 with cam
I have an after market exhaust and the rear muffler started to rattle, after inspection I found something had come loose inside??? Have taken it off and just replaced it with some pipe. Car is a bit loud now (will probably have to get another muffler)
Anyway my question to you in the business is ... should this have affected the cars performance??? If anything I thought it may have improved it, yet I`m sure it feels a little slugglish??
Your comments please.
