dented downpipe
installing new exhaust system on my 95 and under inspection of the old one I noticed the downpipe is dented quite a bit. curious I looked into it and got two answers of how/why it is. one is that it's factory spec for clearance reasons the other is that it's from the front axle smacking it and causing a dent..... I still don't know so which is it?
most off all if you have done a new exhaust with a new downpipe how did it work out clearance. any issues there? if it is an issue with the front axle would a flex joint in that spot work so I don't get the same dented in my new pipe......maybe just another reason to finally get around to that lift I've been itching to do

Re-route the front pipe, eliminating the "crush" and feel the difference in power.

No documentation except what I was told by a friend in JeepTech who worked on emissions compliance as one part of his job at AMC. I was Service Manager and Shop Foreman at a Jeep dealer from 1980 through 1992 and worked with him during that time.

I have my local muffler shop make and install it. If you're lifted 3" or higher, you can use the standard routing. If not, the muffler guy needs to route it away from the shaft. Kinda like making a pipe with two 45s instead on one 90* bend.

the theory behind the epa and the dent may be realisitic...
part # 54448 says "federal emmissions" on my cpu at napa
without the fed emmisions- part # 55277

Now I finaly know where the H those dents come from.
As far as flex pipe goes, the only place it belongs is on the parts house shelf. I used to be in the mini-truckin scene back in the day so I was constantly killing crossover pipes. The longest time flex worked for a patch was about 3 days
