Well, crap. After looking at the pictures to see how the kit will fit I don't see how it can clear the hitch. It needs another bend at the rear.


Back to square one. Guess I'll have to get the 3" inlet kit as it has the corner exit.

Unless it's bent enough at the back that it runs straight out under the hitch

Yeah, maybe you're right. I'll have to keep trying to visualize it. Still considering the other kit and just get a reducer. I wish there were more pictures or real companies behind ebay stuff to research. Makes it difficult to gamble on purchases.

I have this kit on mine (no tips but same as above I believe):
https://www.ebay.com/itm/163517845904

I modified it to have the tips 45° out the sides at the back, but recall clearance to the hitch not being a problem. Fitment overall was OK, not perfect but acceptable for aftermarket, better than the other eBay kit I had before this. I think I spent 2-3 days on and off messing around but I'm slow and sort of picky. I had to buy and weld about an 18" extension from the Jeg's Offroad pipe to the muffler to push everything back to the right spot. Clearance to spare and shock on driver's side (tight side) was good, but expect to play around with joint angles and bracket locations to get it to sit just right. I re-used the muffler hanger from OEM system, and had to cut off and re-weld the supplied tailpipe hangers to the right spots to get them remotely in the correct placement as the factory isolators on the frame. If it helps here are some pics







I am definitely going stainless next time, any place with salt is just no good for aluminized pipe. Whatever the muffler is coated with is a joke, it's only been on 2 years. Will be buzzing areas down before winter and spraying with high temp paint to see how long (weeks? days?) that will last.

Thanks, Oxymoron! You mean the supplied welded sticks that come on the pipes you had to remove and re-weld? That was one of the two reasons I was considering this kit. So it just hung at the factory bracket above the axle.

I'm heavily leaning towards the other brand as I really want/need corner exit. I have rear accessory lights, wires, and the huge hitch in the way for straight back.

Yes I relocated at least one of the sticks that fit into the rubber isolators. The other I may have had to massage a bit to get just right if I remember correctly.

Try truckexhaustkits.com as well, I think they have side exit options. They were a bit more expensive as I recall.

Thanks. Yeah, that's the other kit I'm considering.

So since I haven't decided on what kit or design will work, I've been playing around with my current setup, mainly to get it more comfortable for chauffeuring my folks around in a couple weeks.

First, I added a 90 elbow at the end to exit just before the rear axle but all that did was force all the exhaust directly into the passenger doors. One positive is that the drivetrain vibration was mostly gone. So apparently the exhaust is the cause of the vibes. Hmmm. Another downside was that I lost noticeable power from the elbow. I guess even a little turn to the flow hurts.

So last weekend I decided to cut off the 90 and grab a 45 elbow and another extension to make it dump towards the ground just in front of the axle. So now it doesn't smoke out the passenger side and flows straight back to the axle but pointing to the ground. No more nasty cloud for the passengers and the power is back! But so are the vibes. Hmmm. It's very interesting how just a little change can cause or remove vibes or free up or restrict power.

Meanwhile, I'm still debating over a chambered Flowmaster or the FlowFX muffler kit and whether 3" or 2.5" inlet. There are a lot of positive reviews on the newer FlowFX as it's a cheaper version of Magnaflow style flow through mufflers. I definitely want something that sounds better than a glasspack and exits behind the axles with nice shiny tips. But I'm afraid it will remove power that I've enjoyed with the straight pipe.
