SSEi to GXP exhaust upgrade
 
Thinking of upgrading my cat-back exhaust. Is the GXP exhaust bigger (2 1/2"-3") then the SSEi, would it bolt right on:nm

It is bigger and does bolt in place. SawGunner put GXP exhaust on his SSEi so he can give you the complete details. He posted a video of it in his one thread of how it sounds.

SWWEET:thumbup2--I will see you Sat.:w3 Is it 3"?? I got a 3" downpipe w/ highflow cat wanna do 3 all the way!!

sawgunner 04-07-2010 09:49 PM

it is 2.5" the SSEi exhaust is 2.5" from the down to the front of the res and then 2.25" the rest of the way back to the tips

sawgunner 04-07-2010 09:59 PM

there is really no need to go 3" all the way back the GXP exhaust is really good at flowing plus it sounds deeper than the SSEi one. all you have to do is cut yours off 3" behind your res and the GXP will slide right over it and weld it on

Bonneville'n 04-07-2010 10:07 PM

Sounds good, cant wait to hear it! Hope'n that Bill will help me put the DP on Sat.
