I just purchased a gmmg... i have pacesetter long tubes and texas ory o n the way.....is it worth it to get a cutout or is it only 1-2 horsepower?

 

If you have an offroad y-pipe, the gains are minimal. If you didn't have ORY, I'd say get a cutout before the cats if possible. Do a search, I remember a few threads about this.

 

Yea i tried searchin and didnt come up with much except puting dual cutouts right after the headers and it was a lil to loud for me i wanted to know about one in the I pipe with gmmg. But i guess gmmg is one of the better flowing cat back so i guess im not going to go with a cutout

 

i have GMMG, and right now I'm running an open y-pipe cuz i have to get my cat-back fixed(long story). no gains - actually, i think my car likes the gmmg setup more than the open y. so.....no cutout for me. plus i think it just sounds like **** compared to the beautiful sound of the GMMG. i'll prolly add a twister or bullit to get rid of the rasp i have from 1900-2400 rpms, since thats where most of my daily driving rpms are.

 

ok cool so im going to leave it alone then. hopefully its not too loud on the highway! lol
