Add Ons ?

[buff6116]

So I was wondering what you guys thought about getting rid of the cat and going with a off road down pipe and if I did that should I get rid of the resonator? The only other thing I was think to add to that is a cold air intake. This is on a stock GT with 155,000. This is mainly for MPG reasons and for a little extra HP. Any other good cheap add ons.

You won't get better fuel economy.

Unless you add fake O2 sensors (called MIL eliminators) you will probably throw a code and get WORSE fuel economy.

Since your cats are integrated into your exhaust manifold, you can't exactly just "cut" them off.

To do it right, replace it with a header like this one - http://www.thrashercharged.com/store...t_headers.shtm and then get an exhaust behind that.
