MBRP Off Road Exhaust Kit, it relocates the muffler forward, sounds incredible.

 

second this

 

Pinned in first gear under a bridge is the sweetish sound, isn't it?

 

I'll try it sound good with no drone in the 4 door. My buddy with a 2 door liked it so much he did it it Louder in his. I had to because of when my cats went they clogged the muffler.

 

I have a 2012 Sahara unlimited with Gibson dual exhaust muffler. It sounds great but not over bearing and no droan.

 

Right now we have a great deal going on our cat-back systems for the JK platform.

Dynomax® Performance Exhaust | Promotions

A few cool things about our systems:
Made in the USA!
90 day sound/performance guarantee, if you aren't happy return it for a refund.
Stainless steel construction for a long life.
Limited Lifetime warranty, save that receipt.
So many different options for the JK.
I like our Evolution Competition System or our "rock crawler" system.
I run our "rock crawler" on my 2013 JKU.
Sounds great, I drive around with a 5 year old and a year old, not too loud but great sound when on the throttle!

 

+1 for Dynomax! I run their system that dumps before the axle, forgot the name. But I love it couldn't be happier! Nice growl at the lower RPMs and upstairs it sounds mean too. Highly recommend it
