@rustyoljeep242 in his defense, some Jeeps do have V style motors... theres just two extra cylinders... they're called V8's.... lol i guess his username says it all
First of all that setup is not road legal in most states and messes with the cars back pressure. Secondly that is not a straight it is a v6 The older jeeps 87-91 used what is called an inline 6 4.0 The newer jeeps are made with a v motor
@Newbieman420 Sorry to disappoint you but you are living up to your name. You must be new to this XJ thing. The 4.0L is an Inline six motor. The only V-6 put into a XJ was a 2.8L and it had a very short lived life in the 80's.
@Newbieman420 Are you serious? I HAVE A 2000 JEEP CHEROKEE. It has a 6 cylinder, 4 Liter STRAIGHT SIX. I think I would know, I've seen the engine under my hood. It's not a V. Not even close.
@Newbieman420 wow haha. Yeah my 2000 so it must have that v6 but for some reason whenever i work on it all the cylinders are in a row! just like an inline 6 but it cant be because it's a 2000.
@Newbieman420 There's no such thing as mythical "back pressure". Positive pressure inside the exhaust system doesn't help the engine run any better. However, there is an ideal pipe diameter that's based on the engine's displacement and operating RPMs, that ensures that the gasses "pulse" through the exhaust system. The differences in pressure help to draw the exhaust through the pipe, so that the engine doesn't have to work so hard to push it out.
@Newbieman420 Not to beat a dead horse, but I own a 2000 XJ and it has a 4.0 straight 6 engine. NOT a V6. They didn't start with the 3.7 V6 until the Jeep Liberty as a replacement for the Cherokee in 2002.
that sounds amazing best ive ever heard good job man and what all is done to it?

Newbie, educate yourself. The 4.0 INLINE 6 was used in xj/mjs 87-01, yjs 91-95, tjs 96-06, zjs 93-98, wj 99-04
I invite the skeptics to check it out also. Happy Thanksgiving!

@rustyoljeep242 Yep, that's 100% correct. And I must say, the Jeep 4.0l L6 is one of the best motors if you are looking for long running life

how do you deal with the pressure, because i know you have to have a certain pressure in the exhaust system so you won't lose power or torque
