you can get the stock vacuum system to work if you dont want to buy anything else, its not hard to do. I have duals with turn downs infront of the axle. I used to like it, but now its too loud and fumes come back into the jeep sometimes. If I could do it all over again I would purchase headers that the collectors point straght down. That way I could cross over under the oil pan and run a single exhaust. That way there are no exhaust lines near the brake and fuel lines. Also its way cheaper because you only need one muffler and resonator (if you choose to have one).

This.

I have 11.5" of lift, so clearance isn't an issue, but I'm not happy about the exhaust running right next to the fuel and brake lines. I am running dual 2 1/2 with flowmasters off of Hedman hedders. Runs well and sounds good, but i would prefer a single 3" out the back on the passenger side

With that small of an engine, I'd stay away form the purple hornies. I have fenderwell headers on my 304 V8 CJ with a set of purple hornies and have no bottom end whatsoever. The headers have a 3" collector and the purple hornies that fit are way too big for that engine. Now don't get me wrong, once above about 3000 rpm it's sounds mean. Like I'm racing in a nascar race down the road. But that hasn't helped my mileage any.
