Chevy 350 exhaust

I have an 86 cj7 with a small block chevy in it. Want to get the exhaust running out the back instead of side exhaust and toned down a bit. Fumes to strong. Any Suggestions?

I have block hugger headers with duals that exit behind each rear wheel. I'm really happy with my setup. The fumes are no where near as bad a side pipe exhaust.

I have an SBC and went with factory manifolds, (get this) a catalytic converter and Dynomax muffler - single 2.5" exhaust. The Jeep is relatively quiet at idle and sounds like a Corvette at WOT. The builder talked me into a high-flow cat' - saying it helps to clean up the fumes and smell of the exhaust. Originally, I thought I wanted headers and duals - for power. But man... I don't know what I'd do with more power. On the street, the Jeep will spin or bark the tires in any gear - literally, if I'm coasting in 4th gear and stomp it, it'll bark the 35s. I assume part of that is the fuel injected motor - quick throttle response, etc. But the 2.5" pipe sure doesn't feel like it's holdin it back.

The small diameter pipes help with torque, as does FI.I have TBI on my 350 and its nice runs clean . I dont notice much fumes . I did siepipes and fenderwell headers.

I'm not familiar with the 350 in a CJ, but here's what my muffler guy did with my AMC V8. I love showing it off.

2.5" pipe to the Y. 3" pipe to and from the muffler, and 2.5" tailpipe. Flo-Pro MAX muffler.

I dig the sound. It's not overly loud, but you can tell there's more than just a 258 under the hood.
