anyone runnin an aftermarket header. worth the money?

 

i have one not sure what brand, it came with it when i bought it. sounds pretty burly but the header bolts always vibrate loose. probably not alot of help

 

Get yourself a tubular exhaust manifold from a 91-95 4.0 HO. Then, put a 2.5" cat back exhaust with a good performance muffler. I have a FM 40 but, you can use whatever flavor of muffler fits your fancy. That will get you a little UMPH, that you can feel in the seat of your pants.

 

We did this to my son's Renix 4.0 liter and it made quite a difference.
