Hi all,
I just realized that when me and my friend installed my exahust, we ended up using 2 of the stock gaskets on my 3" turboback. I'd like to go change them but I'm wondering if theyr'e worth the trouble? is the restriction from these 2 gaskets significant? am I losing power? any thoughts?

 

Well they are smaller diameter and if I had them on my Evo I would run with them until I could get the correct size. You dont want to spend all that extra money on a good exhaust and waste it with an exhaust leak or hinder the flow of a good 3" system with stock size gaskets.
