Whether this is a re-post or not I feel that people that plan on upgrading their exhaust systems should take a look at this thread. I find it very helpful. There is no need for a 3" exhaust unless you plan on going over 300whp which the majority of us on here won't. Maybe admins could sticky this for future reference. Yes I am sure that this topic has been covered many times, I just think it would be nice to find something instantly rather than searching for hours or having people ask the same questions over and over again.
