I am going to put a custom exhaust on and I need some feedback from some veteran wrench heads on what would be the ultimate system for performance. I want to run headers and go all the way back w/under the cab muffler and maybe exit before the rear wheel. What do you think?

I'm no expert, but my first concern would be turning the pipes out before the rear wheel. When going over an obstacle how are you going to prevent the pipe from being sandwiched by the obstacle and frame?

Not sure about cutting the system off before the rear but you have a few cat-back systems that are pretty decent and a couple of header choices including Gibson and Banks. The headers on this engine don't really make a noticeable power difference. You'll see more from a decent cat-back exhaust system than you will when you drop the headers on. I went with the banks cat-back and the Gibson headers. Drop a Unichip or other power programmer on and you'll see a tad bit with a good exhaust header set-up. Just remember this engine is out of a Chrysler minivan......not really built for performance, and not a whole lot of bolt on power other than a SC. As the saying goes “There’s no replacement for Displacement”

I don't really see why coming out before the rear tires would be exposing them to damage more so than in the back where it is now. Even being high centered is not much of a threat being tucked up close to the pinch seam before the back wheel. It would be like you'd have to be sliding on a block of cement to get back in there. Or it would have to be sticking out pretty good to get caught on something from the side. There are some sliders out there that would accommodate making a hole through to exit the pipe and have it stick out an inch or so. Or do I have an over active imagination ? What's your thoughts ?

Out the side I wouldn't see much of a problem I guess I'm just not following how you're going to turn the pipe out before the tire in a way that would be out of harms way in a potential hi-center type situation

I'm going out with my exhaust before the rear axle as well; i've already made my custom elbows for an over the frame and out through the rocker guard. THis way you will be out of harms way, the exhaust tip will be flush with the rocker guard. There will require some internal body modifications though but with no problem!

i learned the hard way how long a $60 stainless steel tip lasts on the trail! hard lesson learned! never again.

Your not supposed to mention that company's name, they've been banned but that's exactly what I was thinking

I had a custom exhaust on my 95YJ and had it dump before the rear axle..It was a mean sound'n freeflow'n system..Unfortunately the "Fuz" thought it was bada$$ too and just had to pull me over.. He noticed that it didn't exit the rear of the vehicle which is a "no no" in the state of MD. So if your state is cool unlike mine..then yeah go with the output before the rear wheels.

That's what I think. The stock ones don't look as restrictive as most factory ones I've seen on other vehicles.

I'd still like to see some dyno sheets though.
