okay so i have a 95 gs that i got from my brother. i have no idea wat it has in it other than the obvious upgrades.
that i can see it has a cool air intake and headers..... the exhaust that it has on it i am just not sure. it is wide like maybe 3" or maybe a bit more. before it is flexpipe.
wat i want to know is what is the best thing to do when i replace the exhaust system.
from the headers back wat do i do.
first off what is a down pipe and how does it help. does it go with a cat back or what some one help me figure this out?
