Default Mbrp

MBRP all the way here is a sound clip from mine the day after I installed it. Since then the sound has deepened and is much less ricey.

You referenced torque, fuel economy, and money in your orignal post. Since nobody has mention the setup I'm running I will just throw it out as an option. I have RIPP headers with the hush power resonator and the MBRP cat-back. Together these make a great system.

You definitely gain HP and Torque. I have never had it dyno'd so I would have to refer you to Ripp's site. It states "35lbs/ft or torque 600 RPM sooner than stock and 25 rear-wheel HP gains with excellent response throughout the RPM range".

I did see an increase on my MPG. I primarily noticed it on the highway. I have been running this setup for almost a year but if memory serves me I increased almost 2MPG.

Cost was your other comment. It's not cheap but I do not regret the purchase on bit. The wife has a 2012 JKU and when I drive hers I can't hear it and I can't feel it. I love the sound, the slight rumble, and the added throttle response. This was all notice pre-supercharger fopr those of your looking at my profile.

Money is the ruling issue with many people but if it is not I would go with Ripp headers and MBRP. No questions asked!!!

P/N 17263 is the muffler for this DIY option.

Looking at your avatar and join date, I am guessing a 2 door 2012?
If so, P/N 39524, this is our "rock crawler" system.

Default Dynomax vt!!!

Just had the Dynomax VT installed on my 2010 2 door. When you step on it is sounds great and no drone!!! The guy that installed it was steering me toward anything but Dynomax. When I picked it up he told me this was the best system that Dynomax had ever made and he would actually recommend it to other customers. I feel great about the decision to go with the VT!
