So its time for exhaust and I don't wanna spend the money on a exhaust system and have it hardly any louder than stock.... I had a straight piped Cummins before my jk so I'm use to the loud can hardly hear anything noise..... so long story short what systems are the loudest? I've heard Gibson is one of them for the jk? And no I'm not straight piping the jk

 

Take it to a muffler shop if you want it loud on the cheap.

 

What muffler should I run?

 

Flowmasters are always a nice loud choice... you need to be careful with cheap systems because they will be loud but not very deep... I am more of a fan of a deep growl myself. and i say that with a honda racecar in the driveway lol

 

As you may know, the JK's small six cylinder engine can't push the volume of pressure as your Cummins or a gas V8. Plus you want to maintain a healthy amount of back pressure, otherwise you'll lose power and the exhaust note will fall flat.

I'm a huge fan of the Flowmaster tone and the balance of power vs aggressive tone that they attain. Currently, I have a Flowmaster Super 44 that is located along the driver side with a 2.5" pipe exiting in the rear. It sounds great and it's certainly more aggressive than the stock exhaust. The Flowmaster coupled with the drop-in K&N filter gave me a pleasant throttle response and slightly improved MPG.

If I were you, I would visit a local muffler shop and discuss your wishes and end goal. Plus you'll probably save a bunch of money!

 

If you're looking for a deep growl then I'd look into checking out the Dynomax Ultra Flow SS. I bought just the muffler off of amazon for $70 then took it to an exhaust shop to have it welded in although you could very easily put this on in your driveway with some exhaust clamps. I had mine tucked up high and had them dump it right before the axle. Doesn't drone enough to drive you crazy, you will hear it but it's nothing bad.

 

Cool thank you guys for all all the info!!! I love the deep throaty sound so maybe I'll go with a flowmaster?! Do you guys have sound clips?

 

I really like the sound and 'drone' of my Gibson Split Cat-Back dual exhaust

It looks pretty cheesy with the tips on (and they get munched while wheeling) so I just took them off.
