Exhaust Systems
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/
That said I do like the MRBP relocated catback system

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

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.
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
