$68 Summit Racing exhaust install
This modification uses one Summit Racing glasspack muffler ($21.95) and two Walker mega – clamps ($13.99 each) to produce an inexpensive Cat-back style performance exhaust without having to weld. It is very easy to do and can be done in your driveway.
http://my.project-jk.com/data/500/me...xhaust_003.jpg Modification time: 1 hour Tools required: 15 mm socket 5/8 inch socket Socket wrench Torque wrench Breaker bar Sawzall with metal cutting blade Parts required: Glasspak muffler Stainless steel band-style exhaust clamps (Lap Joint style) Start by removing the factory muffler. Simply remove the nut on the stock clamp and work the muffler back and forth to remove from exhaust pipe. This may require the breaker bar to loosen the nut. Remove the muffler hangers from the vibration hanger brackets. I’m sure there is an easier way to remove them but I use the sawzall to cut of the tip so I could pull the hangers out of the rubber brackets to finish removing the muffler. http://my.project-jk.com/data/500/me...xhaust_001.jpg Stock muffler after removal http://my.project-jk.com/data/500/me...xhaust_006.jpg Exhaust pipe after factory muffler is removed. http://my.project-jk.com/data/500/me...xhaust_009.jpg Locate where you want to install the new Summit Racing glasspack. http://my.project-jk.com/data/500/me...xhaust_002.jpg Use the Summit Glasspack to mark the exhaust pipe and cut the exhaust pipe with the sawzall. Remember the exhaust pipe goes inside the glasspack so make sure you take that into consideration when marking where to cut the exhaust pipe. Place the clamps onto the exhaust pipe. http://my.project-jk.com/data/500/me...xhaust_005.jpg Slide the glasspack onto the exhaust pipe with the inlet toward the engine and attach the clamps. The clamps should be centered on the glasspack and exhaust pipe. http://my.project-jk.com/data/500/me...xhaust_014.jpg Remove the paper from the clamp seal putty and torque the clamp bolts to 50 - 70 foot pounds. http://my.project-jk.com/data/500/me...xhaust_015.jpg Completed assembly http://my.project-jk.com/data/500/me...xhaust_010.jpg I did enlist my wife to approve of the sound test and I am proud to say my JK passed. It has a deep throaty sound without the “too fast too furious” rice burner tone. It has improved felt horsepower along with my CAI.

No chance in hell...if you believe that...well, I have a bridge to sell you. :rollingeyes: I do appreciate the write up and pics!:yup: Looks like this could be done with any muffler. Kudos for trying it!:toung: |
Good idea...I would like to see some type of a tailpipe too though.

I am thinking of thermal wrapping the glasspack or relocating the factory heat shield. The heat isn’t bad I just want to be cautious. |

Any sound clips? I could swing $30 this weekend but if it sounds like ass no way can I swing $500 + to have it fixed.

I had a muffler shop bend a tail pipe after I tried running without any muffler. I was only charged $20 which I thoght was reasonable. Thats up here in Canada. It sounded like crap without a muffler so I had a Flo-Pro cut in a week later.
|
yes, please post a sound clip. i've only heard glasspacks once before on a v6 and it sounded horrible.
i doubt you got anywhere close to 21 HP out of that. maybe half that, but you can't really tell without a dyno run. but this write-up definitely got me thinking :) which muffler?? which muffler?? |
