does anyone have any dyno results for this?

Don't bother with that, just get a gt take off exhaust or other aftermarket exhaust. but MRT shows the greatest gains.

yeah, i don't mind the sound of the takeoff. i've listened to several sound clips of the MRT, and it just sounds so... raspy really. not that great really. thanks

How much do you gain using the MRT?

I don't think we never seen before/after gains on a muffler except from Justin. The MRT gains were extrapulated, never 100% before and after though I'm do think they show a better gain than the mangaflow. My guess is any straight through muffler, magnapack, MRT, glasspack, loudmouth will yeild a bit more flow than chambered muffler.

Here is a pretty good write up with dyno results on bolts ons with the 4.0

Cool! Thank You. That was a good write up.
So the jist I got was even without a tuner, you can get about 5-6rwhp adding the CAI. Then another 10 rwhp with a good axil back kit or GT take-off muffler.
So my 1st mod after getting the windows tinted will be either the CAI or the flowmaster axil back kit.
