i want a whole new exhaust system including the mainfold/headers is worth putting aftermarket headers on it? if so what brand

 

Hey from what I hear this is about the best header for your engine I just put the $67 one in myself just be aware of the tourque pattern when you install it. It is a direct fit for the stock exhaust system.

Can we please have some more info? what year is the jeep? anything 99+ has a hard tme finding headers to fit i have only seen one place that has them and they are super pricey. for the exhaust you should check out mudfrog on the venders page they have a good deal thats worth it all you need is a high flow cat and the kit would be good

 

go catback with a hiflow cat. catback means its just pipe past the cat and from the cat run 2.5 inch pipe. the bend over the axle is really restrictive so 2.25 makes it like 2.0 and ya

start with a good header like this.. then a good cat... then a decent muffler... and 2.5 out the back...still going to cost you $500+
