idk what exhaust i should get.. i already have a vibrant 4-2-1 header and vibrant down pipe.. i was wondering if anyone can help me out and give me some ideas please

 

Look around. Corsa is nice but expensive or you could go to a local muffler shop that does mandrel bending and have them make you a cat back using the prefered size pipping and your choice of muffler. Depends on what sound your looking for there are so many options now.

 

if i had the vibrant header like you i would get vibrant's 3" catback
