I have one that I bought used from another member on here, but haven't installed yet, mostly because I want to get the tips powdercoated black or maybe wrinkle black, and at least one side doesn't come off the backbox I don't believe.
The section that goes under the center of the car is made up of a bunch of short pipes that all V-band clamp together. Better than other clamps, but IMO not as nice as just one or two bigger pipes. (Check out the install guide on their website for more info.)
The previous owner told me the Magnaflow wasn't loud enough for him, which has me hopeful that it will be "Goldilocks" for me. I want a bit more noise than stock, and hopefully a little deeper tone, but I don't want to be setting off car alarms everywhere. I'm 37 and daily drive the car and I've mostly grown out of acting like a bellend.
