Its not going to be anything more than 4-5

 

Yep...I would agree with that.

 

one occasion i like to agree with casper. The main problem with a stock car is breathing problems. You wont get too much horse power out of doing just an echuast and intake system, but what it allows you to do is take advantage of any later modifications you do to the car so that you get cooler air, and less air restriction. Thats all your going to get, ontop of the moter mounts which just help get all the power you just gained onto the pavement. Aside from that, yes stock 00 + neons (SE and SXT) come with 2" exhuast tubing.

my 2 cents
