How would you compare the two?took me somewhere between 2-3 hours this weekend, no lift or jacks on my back.
Removal of stock was easier for me because I had the mrt trail rated already installed.
The connection to the cats was the biggest pain in the ass for me. I don't know who thought of that idea for gaskets, but they suck.
I have to go back under this weekend to make some adjustments, but overall all fairly easy. Just make sure you have something in hand to support the driverside muffler during install.
I have the MRT Extreme and think it sounds great. Just waiting for someone to come out with a good down pipe setup.
