I've installed a K&N air filter....removed both catalitic converters...installed a Flowmaster muffler . I have to travel alot. I'm trying to get all I can out of this "bucket of bolts ".

Welcome to the site Mike.

Welcome to this forum! Why did you remove the catalytic converter? The PCM is designed to run with it. It's also not good for the environment.

I was trying to get the best performance from this vehicle . I was told that these small catalytic converters were very restrictive . The Flowmaster was a left-over from another car . Just trying to let the exhaust "flow". As far as the environment goes . . . my one car out of hundreds of millions doesn't hurt "mother earth". Not on my list of concerns !
