Gotta make this quick...

i got pacesetter lts into a 3in catted y which is currently dumped... if i get gmmgs which are 2.5in will i be looking at gains or losses... thanks!

vivenvex

Also think it'd be a pain in the *** to mate a 3in Y into the gmmg's 2.5"?

gmmg is 2.5" really or just where the y meets the catback i added a new piece of pipe where my borla meets the y so its full 3"all the way back

You should have no problems hooking up a 3" y pipe to a gmmg. The I pipe from the gmmg system is 3" i believe.

vivenvex

ahh so the i-pipe is 3 and tailpipes are only 2.5....

******' SWEET.

well technically the intermediate is necked down to 2 3/4" to mate to the stock Y pipe, though there is some adjustability should you decide to cut it off

I'm sure it wont be too back... gonna have to make a cut in my Y anyhow as i had a shop weld a turn down on the end of the Y for now... sounds sick but hangs a wee bit low and dont wanna have to deal with the cops yah know.

also how bout those gains/losses?

gains and losses, no idea... i put down 410/375 through the GMMG... never dynoed between catback install, headers or anything... so never found out what I really had stock

ya i was gonna say i thought it was 3 all they way

vivenvex

thats good... the site said 2.5 tail pipes and nothing about the rest of the diameter... so i was basing it off that.
