I been looking for an exhaust set up for my 88 gxl. Anyone got any recommendations? Comments and opinions are welcome. Thanks.

 

straight 2.5'' pipe to apexi n1 duals.. it's amazing

 

since you have an s4 you rely on back pressure. i would go no more than 2.25inch straight down

 

You need to be more specific.

Are you looking for a full exhaust or just a catback, a pre-made kit or a custom setup, racing or street use, and what is your budget?

 

borlas are streetable pretty good performance

rb's are ok to me, didnt feel much difference between the borla

apexi n1 were just way too loud for my taste

corksport almost the same as the apexi

obx hiroshima i just plainly love the sound, has a nice deep tone.

if youre on a budget id get with the obx or corksport
if you feel like blowing off a little more cash id go with the borla, rb or apexi
ive had all these exhaust back when i was na the borlas were the favorite

also all these were run with a rb header and bonez high flow cat
