DIY JK Exhaust with Dynomax builders parts
Well many of you would love to free up all that space the giant stock muffler occupies. Well with a few simple parts and some creativity you can do it pretty cheap.
Here is what was used:
P/N 17263 for the muffler http://www.jegs.com/i/Dynomax/289/17263/10002/-1
UFW Stainless Steel Polished
Sound: deep performance sound
straight through design unrestricted exhaust flow and reduces back pressure
About a 5-6 out of 10 for sound.
P/N 51804 For the VT muffler http://www.jegs.com/i/Dynomax/289/17956/10002/-1
At cruise, no drone because of the valve technology.
Stainless steel
Great sound when on the throttle but mellow when cruising.
P/N 51084 Turndown
Here is why we chose Dynomax
Made in the USA!

90 day risk free trial offer, if you aren't happy call DynoMax.

They offer builder parts for the DIY crowd.
Complete stainless steel cat-back system available for most applications.
I choose to make my own hanger with some flat steel and one of the old Hangers I cut off the Jeep from the factory exhaust.
The install is pretty simple and will be even easier if you have already relocated you EVAP.
As you can see I had already relocated my old muffler a few years ago
So you want to cut the old stuff out a sawzall works really well for this task
I welded the turn down in on the VT right where I wanted it so I could cut the factory pipe right where I wanted it. You can use the standard muffler ubolts if you'd like but they are junk. If you dont want to weld I would recommend ordering the stainless muffler clamps when you order your muffler.
Next you will need to make your rear hanger. If you have a muffler Jack it makes life very easy or if your doing the install in your drive way a standard floor jack should do the job for you.
These two holes are where the factory Evap canister was located and they make great mounting points for your rear hanger.
Here is the hanger I made that took all of 2 mins to come up with. I used the stock hanger and isolator just welded to a piece of flat bar.

And for the attachment to the factory pipe you can uses a clamp and viola you have a bitchn new exhaust set up on the cheap using a high quality muffler.

Here is the same install using the other dynomax muffler
This was completely weld-less install minus the hanger that was made. If you wanted to spends some time at your local auto parts store they have a variety of exhaust hangers if you dont have access to a welder.
We will be doing a Video segment featuring these two mufflers for Dynomax so stay tuned for the next episode of Asylum TV for some sound clips.
