Question

I WANT TO GET MORE OUTTA THIS SUV,I LIKE TO KNOW WHAT BOLT ONS AND EXHAUST I COULD GO WITH ?

Answer 1

Not gonna happen with that engine, swap it out for a 5.0, which was a option that year..and there is a ton of high performance stuff for it..

Answer 2

You can get some HP from that engine, but it is going to cost you $$$.  You can get K&N intakes system (I think stage 3),  JBL made headers for it and have CAT Back system.  I like Flowmaster 40 series.  The next thing would be remove any excess weight on the vehicle (back seats)..  I would also feed the engine with mobile 1 synthetic oil, as well as transmission fluid to synthetic.  

Answer 3

An aftemarket high flow cat and 2 1/4 to 2 1/2 inch exhaust pipe and matching good flowing muffler.  K&N filter.  Headers.  Check on line to see if a performance chip is available.

Advance timing and use premium gas will also get more power.

A little bit of HP can be gained by changing all your fluids (rearend / transmission / engine) to synthetic oils.
