exhausts

Post by chris » Wed Apr 18, 2012 2:30 pm

Okay, so I know next to nothing when it comes to engines (I brought the car so I could learn) but basically, what i was thinking is, it'd be quite cool to have twin exhausts (one either side of the car) Now, how would I go about thi all? :)

Twin-muffler exhaust with rear bumper cutout. Do it.

Basically you'll need to have your muffler split towards the rear to two muffler sections, and presumably will need to fabricate appropriate exhaust hangers/mounts.

stainless is more expensive but will probably last longer and sound nicer

are you planning on turbo or supercharge down the road?

Turbo is the long term plan! :) But I figured, if the twin exhausts wouldn't cost to much I could get them done soonish :)

just have to make sure that it is sized appropriately and will match up to a downpipe without too much hassle
have you decided what size turbo/Power output you want?

duals are expensive, heavy and performance wise useless on a engine not in a "v" confirguration

But they look nice...
