Update: I am on day 2 with the Magnaflow installed. I definitely have to agree that there is a very noticeable drone around 1500-1900 rpm. Idle is a near silent low grumble (good) and accelleration sounds amazing. All-in, I am on the fence with this one. It really lacks refinement in that it seems to resonate a bit too obnoxiously for me at the aforementioned 1500-1900 (50'ish mph?). It loses that loud resonation and settles well around 2krpm+ (60-70mph?).
One major issue I have with it is that you lose some ground clearance. For whatever reason, the muffler sticks down half an inch or so below the frame rails. The thing I dont get is that there is plenty of overhead room to have piped it up at a better angle. Thankfully I dont have rock climbling here in the desert, otherwise it would be a prime target for getting slapped flat faced into a rock.
Clearance on the oversized spare wheel was very good. Despite having a slightly larger diameter pipe, it's got a solid inch of clearance from the tire. Everything from the muffler back fit up exceptionally well.
I will be sure to upload a pic or two in the next couple days.
