well, i got the magnaflow installed yesterday evening and it ended up being one thing after another... first, after i put my jeep on jack stands, i unbolted the stock exhaust and released the hangers and for the life of me i couldn't get the stock muffler and pipe out from under there... it was like a cruel chinese puzzle or something... i'm sure if i could have jacked it up higher or even had it on a lift it would have come out no problem... so i ened up cutting the tail pipe off just after the muffler to get it out...
on to the install... went smooth... but i had to cut a little plastic off of the back bumber because no matter what i wiggled and adjusted the exhaust tip always touched the bumper...
went for a drive and an annoying rattle developed... still have to get under there to see what it is, but i'm thinking it's where the tail pipe comes very close to my Hidden Hitch bracket on the forward most corner... not sure what i'm going to do there, but worse comes to worse i'll drop the exhaust again and grind down the hitch bracket a little for extra clearence..
other than that, it sounds great... very sporty sound, but nowhere near sounding like a "Japanese vehicle" or anything like that... got my wife's approval (except for the rattle)...
there's definately better throttle response which was noticeable right away... i'll post back later on any mileage gains if any and what i find is causing the rattle...
we only drove around town a couple times to listen to it and when the rattle started, we headed home and i called it quits for now... i'll probably look at it again tonight after work/golf
