Getting ready to put an exhaust system together for the CJ5.

Just wondering what components are good.

I'd like to have everything flanged. I foresee three sections

Downpipe
Muffler
Tailpipe (goes over axle)

What types of flanges are good. Something that makes a good seal and uses a common gasket. Toyota, GM, Honda, etc. etc.??? Factory stainless chit would be nice. What could I cut up and steel the flanges from? I'd like to stay around 2.25"-2.50"

So far I am considering a magnaflow stainless muffler.

Is it actually all stainless (internals also)?
 
i do stainless steel welding and fabrication for a living and though i dont know what is best for exausts but let me offer a tid bit of info..... take a peice of 11g stainless drill a hole in the center and bolt a steel bolt to it. then take the same size 11g carbon steel drill a hole and bolt on a stainless bolt. then leave it out to the weather for a week. what u will find is the stainless will kinda attract and push rust on to the bolt rusting it out in short order.. and with the carbon the ss bolt will also draw and push rust to the carbon rusting it from the center out.. so basicly my point is that ss and carbon mixed will cause faster rusting of the carbon...so either go all SS or go all carbon.. i in fact have a winch box made of 1/8 ss bolten inside my carbon bumper.. but i have plastic collars on the bolts so there is no SS/carbon touching. thats just my thoughts.. take it or leave it.. :)
 
Anyways

Going with all stainless

Stainless Tube Anybody know a good source?
Stainless Muffler (magnaflow looks like the front runner right now)
Stainless Flanges
Stainless Hangers (will probably end up fabbing these myself)
Stainless bolts.

My headers are already stainless.

Good choice man.. You will be happy in the long run. I have got a lot of my inter cooler piping on ebay. thats a good place to look.
 
everyone i know says that they dont really like the magnaflow mufflers...but its just my opinion
 
I don't know

Just out of curiosity, what exactly do they not like? What vehicles did they have them on. I am still researching, so any input is welcome.

I've done a lot of searching on various boards. People either like Flowmaster, or Magnaflow. I've atually seen more good reviews of Magnaflow than bad. There's the odd bad review though.

I had Flowmasters on my Mustang. They were amusing at first, but got really tiresome. I was impressed by the sturdy construction though.

From what I've read about the Magnaflows, they are supposed to be a bit mellower than the Flowmasters.

I would actually go with a different series flowmasters (50 perhaps), but they don't appear to make them in stainless.
 
yeah thats what most people go with is the flowmaster 40 series

they just didint like the way they sounded..i never really did like the way they have sounded either, a guy had one on his 95 camaro and another was on an 85 chevrolet..i have the new cherry bomb on my truck..i like the way it sounds, but that might just be because its my truck

every mustang i have ever heard sounds crappy, i guess its just the way they are set up
 
your not going to find many mufflers in stainless from the big names...not so sure why...but if you want to go stainless..i reckon id go with magnaflow as well...
 
i have a magnaflow on my 98 durango 5.9l it came on it when i bought it used. it sounds realy good.. but i dont have a D with a flowmaster on it to compare it to. but like i said the magnaflow does sound good.

not many use stainless for the reason i stated befor... stainless and carbon dont mix well.. so just one stainless part of a exaust system makes not much sense. not to mention that they can aluminize carbon to inhibit rust for much cheeper than stainless..
heat also warps the hell out of stainless.. i don tknow if exause at the muffler is hot enough to do this but its a thought...bottom line not very much of a market for stainless mufflers unless your in to the import car scene and lookign for soem bling bling..
 
Well

I also suspect that they don't want to make things that last forever. The car companies figured that one out a long time ago.
