Gibson Performance Exhaust 17303-B BLK Split Rear Dual Exhaust System

Have had mine for a year and a chunk of change now. I have taken my Jeep out into almost every terrain and weather there is. This thing is loud. If you don't want to have to turn up your radio to drown out the noise then I suggest you look elsewhere. I have had no issues with any drop off in power, acceleration, or response. The battery trick just resets your computer to its default settings. I would advise buying a tuner or going somewhere to get your vehicle tuned after installing this as there is a slight change in the way the computer reads the exhaust system after adding this. Gibson did a very good job in attempting to eliminate the "ricer" sound, but it is still there depending on the temperature. Mine has gotten better with time, although this is mostly from changes to the engine and computer, not the exhaust itself. I have not noticed any change in mpg, but why would you buy a Jeep if that is one of your concerns? I guess if you're that joker who waves at other Jeeps from your stock set up then maybe. Overall, this thing looks great, sounds great, and can take some hits from terrain if installed properly (do yourself a favor and weld this on and put some flexibility in your mounting hardware). I will buy in the future if I can ever bring myself to trade my baby in for a new one.

Start up sound is moderate, not to loud. Acceleration is pretty moderate too, once you really get on it you will open it up a bit. Overall the sound is very nice, not to loud but it can be. Mine has a bit of a rattle right now at the higher RPMS, but I'm pretty sure that's just because it's a brand new exhaust with about 5 miles on it. I'll update if it isn't!INSTALLATION PROCESS: The rubber mount on the left side (while looking at back) is the easiest one to get, it's also the one I suggest getting first. Mainly because the mid pipe is connected right beside where this mount is, and if you are doing this by yourself you'll want the help from that to keep it steady. The rubber mount to the right side (while looking at back) is the worst. I would suggest putting the jeep on roll up's just so you can get better leverage. It's a very tight space and you will need a whole bunch of WD40 and leverage. Other than that, once you get it off, it takes about 5 minutes to install. I didn't disconnect the battery, as it really isn't necessary in this install.

Overall Impression:For the price, I definitely recommend this for a Wrangler. In my opinion, the sound is very "sporty". It has some deep tone to it at lower RPMs, but once you pass 2k RPM it starts to sound almost like a Porsche. I'm speaking about what I hear from the driver's seat. The sound outside of the car might be different. If I have an opportunity to have someone else drive by me as I'm standing outside of the Jeep, I'll update this review with that impression.Installation/Fitment:So this is where this product lost a couple of stars for me. I installed it myself, and the fitment was a little off until I tweaked the hangers. Perhaps a shop would be able to bend the hanger rods or something to center the pipes under the rear bumper, but mine was noticeably off-center when installed without modification. Also, there is a an index point on the factory pipe that should line up with a notch on the muffler pipe... but mine was off by about a half-inch. If I lined up the point with the notch and left it that way, the right hanger rod would not have gone into the hanger grommet, and the muffler would be tilted high to low from left to right of the vehicle (if that makes sense). Unless I messed something up (possible, but low probability), it seems that this wasn't meant to fit perfectly on a 2015 Jeep Wrangler JKUR.Bottom Line:With some ingenuity, experience working on vehicles, and ability to tweak installations to fit your needs; I would still recommend this to someone who wants a relatively affordable way to add a better sound to their Jeep. All said, I would purchase it again.

Service & Shipping was fast. Box was a little beat from inside, the brackets on exhaust rubbed holes. Black ceramic coating was perfect. Exhaust fabrication was better than expected. The tips look fine too. Makes a V6 JK Jeep sound like a V8 when starting cold, but quiets down. Little loud inside at 2K RPMS / 75MPH, but you can control the drone sound by adjusting throttle. Wide open throttle not bad at all. Seems that I am getting 1 to 2 MPG more. Makes a Jeep even more fun to drive. Yes, you might wake up your wife at 5A.M. leaving for work. Sweet!It's now 4 months later and like the exhaust even more. We have noticed that the over all tone has deepened for the better with little carbon build up inside. Paint still looks great. Recently checked torque on the nuts and snuggled them a little more. Statisfied with this purchase.
