What do youall think is the best downpipe brand and size wise? i have th gmpp header and gmpp sport exhaust so i was just wondering what would get the best hp gain.
thanks!

 

see if you can pick one up off of an LSJ... it will be the least expensive and will be a perfect fit

 

is there a noticable hp gian from the lsj downpipe?

 

i got a ca header and stock exhaust, i put an lsj downpipe in a little while ago and was very suprised at the gain it made. no fitting issues and was real cheep. aftermarket dp start at 2.5 inch which i think is a little big for our na 2.2s

 

i got a lsj complete exhaust, header, dp, anc catback, the difference is felt, the RPMs pic up quiker, i recomend the lsj dP
