Dual Exhaust????

I'm looking to replace my ZJ exhaust and I wanted to know if there is any dual exhuast systems.. I really like the look of the exhaust tips on both sides of the car, but have yet to find something made for a 94 ZJ.

4x4 or 2x4?

Your best bet will probably be to run a single large pipe then split into two smaller pipes at the fuel tank.

I have a 5.2 v8 4x4, any suggestions on a setup that comes ready to install like that.

None that I'm aware of..
You could contact Nick (kolak@aol.com) and get the 2.5 inch exhaust system, and have your local welding shop weld it up and manufacture a 'Y' at the gas tank to split the system and make the second exhaust tip.

just run separate pipes from each bank and have them exit just before the rear tires...can use a crossover pipe if you'd like, but it really isn't necessary. This would be the cheapest route you could go.

That won't work very well in a 4x4. You run into interference issues with the front drive shaft.
Also, a crossover pipe isn't necessary, but it's purpose is to help keep the back pressure balanced on both banks. Further, it's location directly affects the torque curve. It's been an awful lot of years since I messed with duals, but if I remember correctly, the closer the crossover tube is to the manifold the lower in the rpm range you feel the torque.

I have looked into this and none of the muffler shops I have talked to recommend this on a grand. About 80% told me that there was not enough room really to run a true dual exhaust and it would help the jeep perform any better.

Why would you want a dual exhaust? If it's a 5.2 it doesn't need more than 2.5" piping, better to spend your money on some headers and mandrel bent exhaust.

BTW - it can be done, it's just not easy. KRC's project jeep has a true dual 3" exhaust. But that jeep is running a 5.9 stroked to 408 with nitrous.

I have true duel on my jeep but like wvd said it would interfere with the front driveshaft. The reason mine is fine is because i converted mine to rear wheel drive. It was prob a dumb move but i like the exhaust coming out from the sides of mine. It all up to you on wut you would like to do. Most likely if there is a custom exhaust shop around they could do it but ur prob better off getting a nice set of headers first.
