    i just installed the flow master american thunder setup. 1 1/2 hours taking my time. fit is excellent. entire instal was fairly easy for one person. it is a little louder than i anticipated. however, after a few miles it might settle down a bit. i have an ultra gauge, so i am going to see if the mileage increases at all. seems to have a bit more pep to it. $477 shipped free from patrsgeek.com.

    after driving for about 40 miles in 2 days, i discovered a problem i have contacted flow master about. will post resolve then i hear from them. my initial run after instal was 12 miles. let it cool and retighten all bolts. after this ride, i smelled rubber. what i found was the hangar welded to the exhaust pipe where it join the inlet side of the muffler, gets very hot and will melt the rubber hanger. toyota uses a hollow tube, to dissipate heat. flow master uses a solid rod, thereby conducting a lot more heat. we'll see what flow master has to say about it, hopefully before it melts through and everything ends up in the street!!!!

    it burned enough to make me concerned enough to go to toyota and buy a new rubber hanger. i really like the system. nice sound.very meooow at low speed low rpm. you get on the throttle and it gets louder, not obnoxious tho,,,, i would buy it again.
