I have been shopping around to get a new exhaust system. Does anyone have any opinions so i can get the best performance. Please let me know.

 

I have a friend who owns a local exhaust shop and went that route. I am very happy with it. I am a serious critique when speaking about power "adders", especially on the JK, but this is one mod I can honestly say added some. Not a huge amount, but right in the range where it needs it, around 1500-2000 RPM. It's not a fancy mandrel bent system, but it does the job. You'd never feel the difference between die and block and mandrel bending anyway. I used a Magnaflow straight through muffler relocated under the driver's side, by the way. Here's my original thread with pics and a video to hear the interior sound level. https://www.jk-forum.com/forums/modified-jk-tech-2/new-cat-back-installed-73800/

 

3.8 + aftermarket exhaust = cool noise That said I do like the MRBP relocated catback system

 

MBRP has a soundclip on youtube for you to hear what there exaust sounds like! Mine is on order!

 

I have the wood muffler relo kit, sounds pretty good, have had about a 1mpg increase in fuel economy.

 

Got a Flowmaster 40 series slapped on my JK for $150 even at a muffler shop in town. Sounds good and gave a little boost to performance and mpg

 

I did the same thing- same Magnaflow and location. It's a little on the loud side but I like it that way.

 

The March issue of JP magazine has an "exhaust shootout" article in it. It doesn't go in too deep technically but it does rate a bunch of cat back systems by completeness of kit, ease of install, anf noise levels. It might be on their website too.

 

i have the dual borla axle back and love it very nice idle and awesome sound when you give it some gas.

 

Yes but those tests are all on a TJ, so I would take all of those ratings with a grain of salt since the engines are very different
