The LH tube looks perfect.. Any thoughts

That is not normal at all.. you should get a new exhaust fabbed up quickly!

Thanks for confirming. Sometimes it's more fun (and less $) to be creative

Interesting. I wonder if it actually made a difference.

The crimp is standard. My GTO had it worse than that and we're talking about an LS2 motor w/ 400hp stock. One thing you can do is have your exhaust shop cut out the crimp and weld in a piece of uncrimped pipe.

Over the last several months I've been experimenting with the exhaust on my 2011 JGC with the 3.6L V6 trying to find alternatives to purchasing a $1000+ cat back system. Also, I wanted duals since mine came stock without. I tried chopping off the rear resonator and that was alright (probably should have just stopped there) but it wasn't duals. Then I had the bright idea to eliminate that suitcase of a muffler and straight pipe duals..simply wasn't thinking on that one lol! To avoid further wrath from my darling wife I put on a couple of cheap 18" round mufflers until I decided on a long term solution. This whole time I had been leaning towards the Magnaflow 16929 as several others here installed. I'd even been watching the Classifieds for a used one but to no avail and I wasn't desperate enough to spend $1400 which was the cheapest I'd seen. Last week I had an epiphany! As I was looking at Magnaflow's cat back I realized the muffler, resonators and x-pipe used in it were very similar to their universal products. I acted on a hunch and called Magnaflow and sure enough the components were the same.

In light of the long and probably unnecessary book I've just written above I'll finish with this. I ordered the 2 resonators (part number 12866), dual in/dual out muffler (part number 12468) and x-pipe (part number 10791) from AutoAnything.com for $348. Disclaimer, I ordered over the phone and the representative gave me 15% discount. Anyway, I took this all to my local shop and after about 3 hours but some first class work I forked out $530 for the equivalent of Magnaflow's cat back plus I have that dual exhaust I wanted

I'm working on uploading a video to YouTube for your viewing pleasure
Do you have a part number for the rear plastic fascia/bumper part for the dual exhaust, that needs to be switched out so the 2nd exhaust tip can protrude from the vehicle?

I had my exhaust guys spot weld all the sections that are clamped together. AND Magnaflow was right about the exhaust getting lower and deeper toned as it broke in. About 2 months in and the exhaust is noticeably deeper for me but I like it.
I thought you were a member here! And I do agree with the cleaner look of the actual kit, though I'm satisfied with the end result.

When the exhaust shop was making the bends to connect the dual in/out muffler they came close to crimping the pipe but it's not quite that bad...

So I actually just rigged the lower rear bumper by just cutting an exit for the duals lol! I have every intention of purchasing the actual part and replacing it because if you really examine the piece it is evident. It was all part of the lengthy experimentation I got wrapped up in

Below are the part numbers (found the info in another thread) to do the single exhaust-to-dual exhaust conversion. For the record, I did not purchase any of the following:

Bumper parts:

1. Lower rear bumper without tow package (68111469AA)

2. Heat shield - Left side muffler (68111643AA)

3. Screws (3 or 4) for attaching heat shield to bumper (68090949AA)

4. Push nut/clip (1) for attaching heat shield to bumper (see pic). I'm not sure of the part # (68090948AA)

5. Rivets (2) for reattaching the rear quarter panel molding to properly attach the heat shield to the bumper (6500911)

Exhaust Parts:

1. Rubber exhaust insulator (2) (52128501AA)

2. Exhaust hanger, Left side rear (68056521AB)

3. Screw for attaching exhaust hanger (6101793)

4. Nut for attaching exhaust hanger (6101809)

I just did the same with the 11386 (after they told me to get a larger one) and they turned me away after they put her in the air. Has anyone been able to successfully replace the suitcase at their shop (for HEMIs...I know this is mostly a Pentastar thread)?

Re: OMG! Not another exhaust thread!!

Any of you who upgraded or is in the process of upgrading the stock muffler (single or double) let me know. I am in the market for a stock muffler. Thank you

I had watched your video were you had straight pipes on, is there a reason you went away from straight pipes?

The volume from the straight piped option is not as obvious in the video as in person but it was very loud. My wife couldn't handle the drone (or embarrassment lol) when riding with me and eventually it was on the excessive side for even myself, hence the change.
