Well this past weekend me and my buddy installed.. pace setter exhuast high flow cat and header... I must say what a diffrence.. car does not work hard at all any more.. the header gives the car a nice little raspy feel to it.. and highway speeds are crazy wot from 60-100 feels like it leaps.. I have one problem tho.. my old o2 sensor is shot the down stream is it possible to trick out the ecu with a variable resistor???.. its running pig rich and smells like a lawnmower... but the running lean problem is gone lol... the old exhuast was garbage the cat had a huge hole in it.. one more thing i need to find a front solid motor mount.. any suggestions??? Im going to get some pics up of my exhuast and my buddys corrado..

 

Check out modern performance or howell automotive, both of them will have a PCM so you can run just one 02 sensor and solid MMs

 

Only the '95 Mopar PCM will allow you to disconnect the downstream O2 sensor without getting the CEL. All the other years still have to keep it to be 50-state legal. AFX does eliminate the d/s sensor for all years, but they are more expensive and not 50-state legal... in fact, they are zero-state legal... anywho...

www.casperselectronics.com sells a downstream O2 sensor eliminator/simulator for the 1996-up vehicles. There's no resistor trick...

The AFX solid mount is nice, but lots of vibration. You might consider the firm filled mounts from www.deyemeracing.com instead.

Best of luck!
