Another exhaust question

[DTRAIN]

I have a pro circuit T-4 exhaust with the quiet core insert. My question is, if I take out the quiet core insert and put in the regular, less restrictive spark arrestor, will there be any power difference?

Probably but it'll be very little.

What are you going to put in that is less restrictive? :confused:

take out the silencer core, it is very restricting compared to the normal spark arrestor. The silencer core for a t-4 is a joke, its made from the same spark arrestor only it has a 5/8" fender washer welded to the end of it. So yes you will have quite a bit more power going from a 5/8" outlet to 1.5" in my opinion.
