So I'm thinking about routing my exhaust out the hitch gate, but would love some input on muffler/tips options. I've seen this done on the 4.7 with the hitch bezel, but I've got the 3.7. I don't want much more noise, so I was thinking of just rerouting the tailpipe and adding a split tip. However, I'm not sure I want to be able to see that whole setup from behind the Jeep (looks cheap?). I like the idea of a stainless single-in-dual-out muffler, but would that have to include removing the factory muffler, mounting hang points in the spare well, and dealing with more noise? What about keeping the stock muffler and routing the tailpipe through ANOTHER muffler? How retarded is that? Any suggestions/advice would be appreciated.

Go to Borla.com. They make a few slick ss dual tips. If you remove your spare and resonator, a pipe shop could fabricate what you want. They probably could relocate the resonator in a new location so you wouldn't gain any noise. Post a picture when you decide to do this.:eek:rangehat:

I don't know if the 3.7 has a resonator but if it does it could be moved. I say if you like the sound you have now then simply cut and move the pipe to the location you want and retain the stock muffler. A place that does mufflers or exhaust work could easily make you a Y-pipe and then you can just bolt on a couple chrome tips. Relocating the last couple feet of the exhaust pipe should be an easy job even if you use some of the pre-bent pieces that you can buy at the parts store and a couple universal hangers. All you have to do is cut out the end of the stock pipe, I would suggest doing this at the point above the rear axle, and then test fit the new pieces in. I doubt that the 2 muffler idea would hurt anything but it could cause too much back pressure and I just don't think it is the best solution for your plan. The only 2 issues I see are getting the right shape Y-pipe (if it needs to be anything special) and then relocating the spare.

Someone else suggested hanging the 2nd muffler where I like, but just trimming the tailpipe out of sight - no real connection between the two! Would work, but seems like cheating to me. I may drill out the baffles of the new muffler, though. I just don't see how a high-flow muffler that's been hollowed out could create any more backpressure than the huge stock can.

I remember seeing a picture of someone who pulled off the srt exhaust on this forum, but I might be wrong.

My suggestion was not that you do the "cheat" method but simply connect a new section of pipe from above the rear axle to the desired output location. I would think that the 2nd muffler would just change the sound more than anything but it COULD affect back pressure. Other than that why would you want to spend time and money on a muffler just to hollow it out when you could go get a Y-pipe that will cost much less in time and money.

Relocating the tailpipe straight out with dual tips would be quite easy. My only hesitation is that I wouldn't want to be able to see straight past the tips to the long, single pipe leading there. A dual tip muffler provides that purposeful-looking backplate to fill the hitch hole.
But my biggest obstacle seems not to be mechanical logistics, but rather the lack of logic available to convince my wife that we need to remove the spare so that I can cut a chunk out of the bumper and stick a pipe (or two (or four)) out the back for aestetic purposes only.
She didn't buy into my MPG improvements, reduced noise levels, or better radio reception claims.
Any suggestions for that conundrum? Where is the marriage counseling thread on this forum?

Update:

So I have always implemented the philosophy that I should spend at least the same dollar amount on something that I do want when I am forced to spend money on something I don't want. My failing steering rack has opened several doors for me here. Furthermore, by replacing the rack myself I can save $500, another argument to purchase a fun mod (yes, even though it counteracts the cost saving principles).

So with the same gusto that brought me to do my own rack, I have decided to move forward with the SRT-8 style exhaust project. I ordered a bezel the other night and when it arrives will trial-fit a few exhaust tips to see what will work best. I am leaning towards a pair of Camero style tips that should fill out the width of the bezel opening, but be slim enough to not protrude down too far out of the bumper line.

I am going to cut the stock pipe above the axle and route it to the bumper and add a Y joint for the tips. One of my biggest obstacles was figuring out what to do with/for the spare tire (7% for myself, 98% for my wife). The easy solution (before consulting with my wife) was to just throw it in the back of the Jeep, but the loss of cargo room for trips seemed too much; a new set of run-flats even more. So my proposed solution was to use a bolt-on joint above the axle, keep the spare in the garage during our regular city driving (where a flat would only mean a quick run home), and simply swap tailpipes anytime we make a lengthily trip. Maybe excessive, but what good is cake if you can't eat it, right?

Here's a few pseudo images of my anticipated results (please forgive the quality rendering- I only have Paint on this computer):

Kansas, sorry to get off topic, but what brand/size tires are on that black XK? That really looks nice!

Kansas, love your Jeep man. Can't wait to see how it turns out.

p.s. The tails are looking real nice. Mine were done dull, but I think the shiny look is much nicer. You take them to a paint shop (if so, how much they charging you in your neighborhood) or do them yourself? Sorry for getting off-topic, can't wait to see the exhaust.

Thanks! They're Hankook Ventus ST RH-06 in 275/60/R17- been fantastic wet, dry, hot, and cold!

Yeah, I'm pretty excited to see the setup in person! I think it will look sic on one of our cold days here with the exhaust just wafting up the middle.

And while I wish I could say that I painted the lights myself, I actually paid a shop in CO (Smokey'sLights.com) to do my design. They did a fantastic job- glass smooth. I think it wound up running $245- he did my 3rd brake plus a new set of tails. I could have returned my tails for a $65 core refund, but decided to keep them as a spare set.

Srt exhaust

Here is a picture of mine.. it is not that hard to do. mine is true dual, the rear hanger from an srt8 Grand Cherokee bolts right on to the back of the commander and it's like $80 all of the other hangers are in the same place. I did some custom work cutting the y pipe and making a dual system with flanges so it can be dropped in sections if need be. http://www.jeepcommander.com/forums/picture.php?albumid=301&pictureid=1829

Looks nice! Can you post some more pics from other angles and underneath? What is your spare tire situation/solution?
