New Gibson Stainless Steel Exhaust for the Jeep

By Axial Staff on Dec 01, 2009

Well, I finally got a chance to have the new exhaust installed on the Jeep. As I mentioned in my earlier post, I am in the process of switching out from Colorado plates to California license plates. My old exhaust was pretty much beat, and I knew it wouldn’t pass the smog tests here in Cali. So, I bought a stainless steel header and stainless cat back exhaust from Gibson. I plan on keeping this Jeep and turning it into a full on trail rig at some point, and I wanted the exhaust to last as long as possible. I was looking for a 50 state legal converter for it, but couldn’t really find what I needed. So, I had the shop pull the old exhaust off and tell me how the stock converter looked. They called back a short while later and said my old stock converter looked to be in good working order, so we kept it in place. The shop, Orange County Muffler (1601 Placentia Ave, Costa Mesa, CA)  for those in SoCal, installed the new headers, new 2 1/2″ stainless down pipe, welded that to my stock converter, then installed the muffler and tailpipe. I’ve had the exhaust installed for about a week now and I couldn’t be happier. No more leaky header noise or fumes, better throttle response and way better sound. I have to give a big shout out to Gibson and their products, so far I am very impressed. Here’s a few pics of the finished system.

New larger SS down pipe

New muffler tucked in nicely

There are a couple issues I need to iron out on the tailpipe though. I installed a gas tank skid plate from Tomken years ago and it takes up more room than the gas tank alone, which leaves less space for the tailpipe to exit cleanly. Then, with most lifted TJ’s, the longer shocks will hit the lower coil spring perches when the shocks droop out, thus damaging the shock bodies. You can fix this 2 ways, buy lower shock relocators/extenders to move the lower shock mounts away from the spring perches, like I did. Which will leave you with even less room to work with for the tailpipe to exit. Or, I believe, you can flip the shocks upside down so the shock shaft is on the bottom, which gives you more room for the tailpipe and allows you to remove the lower shock bracket/extenders. I will probably go the latter route and ditch the extenders. Just like a custom R/C build, there is always something.

Here you can see how tight the fit is right now around the shock body and gas tank skid.




Sweetness, I haven’t even turned the stereo on in my Jeep since the install. Got to love that sound.

Next up…………….cold air intake.

    You can’t flip over any old shock for clearance sake. Only certain shocks can be run inverted, your skyjackers I don’t think are one of them!

    Can you elaborate on this anymore? Everyone I have talked to said they will be fine mounted upside down.
