What is the Best Exhaust and CAI for JK

Hi Guys,

Based on your experience, what is the best CATBACK and CAI for the JK performance and sound wise. i like the deep sound.

currently i have a Volant CAI on my sierra Denali and i am happy with the sound, but haven't felt any performance change, so i am not sure if it will be the same of the JK or not.

I run the MBRP offroad stainless catback system. It sounds great, but not loud, and it relocates the muffler to under the driver's seat. Install is cake, takes less than an hour with basic hand tools.

If you have the 3.8L, it's not worth changing. Put the money into other mods.

You can expected the same amount of performance increase on the JK as you got on the Denali .. . . . .NONE, ZIP, Zero

The best you can hope for is a change in the sound and your wallet will be lighter

I run a Dynomax catback and IMO it sounds great, nice deep sound and much better ground clearance than stock. Def no HP increase but I love the sound. In all honesty I think I lost some get up and go with it. OEM removal isn't bad but I strongly suggest spraying the black rubber hangers with WD40 or some other lubricant to help slide out the hangers

truth is so precious that she should always be attended by a bodyguard of lies...

It was easy. Only 12k miles on my rig though, nothing rusted or seized up really. Took less than an hour to rip out the old one and put the new one in.

Not sure if it translates across the auto realm, but when I was building cars, CAIs really didn't make that much difference (besides sound). So I always shied away from the $150-300 'cold air intake systems' that claim 5-8hp (crank hp btw, none of that is perceptible at the tires).

If you want noise, any aftermarket filter that replaces the airbox should do the trick. I ran these on the inlet side of turbos before I fabbed inlet piping and they did just fine
