MoZart exaust

[MentalbassHead]

I have a moZart exaust on my G and i was wondering if anybody else has 1. i just have a muffler i beleave and im wanting to do a 2 3/4" custom piping and maybe a dcsports header im not sure still doing research.

I recently did a search and remember reading that 2.25-2.5" piping would be great unless you have forced induction. Anything bigger than 3" would be pointless. Dont know how true but just a combination of a couple of posts that I have read.

2.75 is not at all necassary for n/a cars. i have 2.5 inch piping and its perfect (even with my nitrous) and i just got a set of amss headers and am going 5 speed soon. 2.5 is ideal without any serious FI.
