i am thinking about putting back on my stock downpipe. i am currently running the helix catted downpipe. i will also be putting on a stock sti exhaust to replace my helix catback.
my current mods are, ecutek, gt-30r turbo, 800cc injectors, uppipe, fmic, and header. how much horsepower will i lose and do i need another tuning? thanks. i have a wrx by the way.

So is it going to be a temporary thing or for good. With all of your other mods, it would be very inefficient with the stock downpipe. Even moreso that with an otherwise stock rex.

what if, i keep the downpipe and switch over to sti exhaust? it's just too damn loud. downpipe maybe for temp, sti exhaust for good.
