The 13b in my GSL-SE has modified 12a headers (they are cut down the middle, i know g-h-e-t-t-o) and the rest of the exhaust system is 3inch piping, so which presilencer do i need to order, and do i just ask a exhaust shop if they can install it ? thanks

 

3" piping, that has to be freaking louder than a mother.. . I have 2 1/2 on mine and I bought a second gen presilencer, take a bit of more modification to the header, but it sounds awesome, you might want a bigger presilencer since you have a big exhaust.

 

it is extremely loud ... its not too bad w/ the silencer but i hate the stupid noise that it makes ... plus it cant breathe i can feel it when i accelerate quickly it backs down i wish i could just drive it the way it is. Stupid "loud muffler" tickets.

 

The GSL-SE presilencer of course .. unless you actuate the 6-ports another way or theyre wired open.

 

hmm i dont have fuel injection tho ... it has a holley carb. & rb intake & exhaust manifold ... does that matter ?

 

TII is 2.50 ID. FB is 2.00 ID.

the choice is yours but If im to buy one, it will be the TII's presilencer.
