currently running 3" blueflame downpipe an decat an have miltex 2.75" cat back. the cat backs not 3" but downpipe an decat is, it the half inch differnece worth much or would not really see any improvments? thanks

on a rolling road test you might see a small gain but i dont think you would notice when driving on the road.

You won't see any difference with a full 3 inch system.What you have is ideal unless your going for serious bhp

will keep it as it is then as going to fit my hybrid an thats why got 3" downpipe an decat. may get high flow mani but not going over the 320 bhp mark.
