I remembered a little while back in a thread about stacks I mention a jeep up here with stacks on it for mudding. Bigblue wanted me to post some once I got a few pictures. I came across a picture of the guys Jeep and his 72 Chevy pick up with stacks.

Here they are....

 

idk if it just me but i dont really like stacks on gasser

 

That's okay, I don't care for stacks on anything short of a 2.5 ton medium duty truck.

I can only imagine the joy of the noise, heat, and Co2 from stacks on that CJ while chugging along a trail in it.

 

Yea I dont really like the way them jeeps looke without lifts, they look kinda goofy (no offense to anyone).

 

Trails??? They are strictly mud trucks for running the mud-runs, they sit in a garage all winter getting upgrades for the next mud run season.

Thats the reason for the stacks is to do the mudruns,they don't do so well going thru that deep of mud with a standerd exit exhaust.

 

Never had a problem with an exhaust that exited behind the rear wheels even in mud and/or water similar to what is pictured.

But I guess if someone is going to use something as inappropriate as a CJ-5 as a dedicated mud bogger, they might as well throw some useless stacks on it, too. Maybe it's just an east coast kind of thing. To each their own, I guess.

 

How long are you in the mud or water? That pit is over 200ft long. Most of the runners are Jeeps. They do perfectly fine,they are the ones to usually win to.

50-100' of mud and/or water would not be uncommon on some trails.

It really does not matter, though. You tend to get get through that stuff by keeping the hammer down to keep the wheelspeed and momentum up. That means your engine is running at a pretty good clip exhausting itself quite well. Were the depth of mud and/or water a genuine concern, you would be better to focus on the intake and engine electrical systems. Stacks really do nothing for fording performance unless you plan to run completely submerged for a while.

Just for kicks, I was perusing the Maine Mud Runs site and saw that their formula for building mud boggers appears to be pretty much like the rest of the country. Full size rigs either lifted to the sky or seriously hacked to clear huge tires, probably favoring big block gassers, Dana 60 fronts, big full floating rears, TH400/C6/TF727 automatics, etc. A smattering of smaller rigs tossed in. And amazingly enough, save for a couple with open headers poking through the hood, none with stacks.

I'd save the little Jeeps for trail riding and rock crawling and leave the hard core mud bogging to big beefy full size rigs. Just my opinion, of course.
