Keep my current duals or go with a single exhaust?

+1 on overkill… single 4 inch is enough to feed a 400-500whp V8…let alone a 300whp turbo 4.

i’d go 3 inch with a muffler. thats plenty. lots of STI’s using 3inches and making big power. same with alot of turbo 4’s

my friend used to have a 11 second neon with open down pipe… that thing was wicked sounding but loud

I duno Ive seen alot 4" exhaust cars… I know when cheeks had his @ 4" with the 2871 with the old exhaust it was obnoxiously loud… I have also heard a few dsm’s with a 4" exhaust on them… and joes car really isnt that loud…
