Stock muffler anyone?

[GTP4]

How much power can they handel?
With my mods on sig:U guys think i'm maxing them out already?
I have a 3"dp and 3" pipe all the way to the Y and then 2.5" to the mufflers.
Im trying to find whats causing my kr issue.

Even then, there isn't much restriction in the stock mufflers, most the exhaust restriction in the 3800 is the front manifold, Cat, and Ubend... the resonator may hurt a little, but prob not to much

no doubt. i have 2.5 downpipe (S&S boooiiii) > 2.5" high flow cat > 28" glasspack > stock muffs.

it sounds badass at WOT. you know, the whine part.

Just asking.
I like the quite sound of the mufflers and the loud wine of the blower myself.
I'll keep looking then.
Thanx.
