the system was installed rather easy . The quality is very good , I'm a little dissapointed in the sound . I thought with a tital like "American Thunder" the sound would be louder . It's slightly louader then my stock exhaust,I'm hopeing it will get louder with time.

I was familar with Flowmaster when I owned a mustang, so I decided to try the American Thunder system for my 2007 Tundra Crewmax 5.7. I wasn't really looking for an expensive exhaust but wanted more sound and a little more performance. This definitely fulfills my needs. While the 50 series Big Block muffler is quietier than I would like, it still livens up the trucks sound. Ideally for me, I would have liked an option to mate the system with a 40 series. The installation was very straight forward and took around an hour taking things slow. I would definitely recommend it to anyone owning a Tundra looking for an exhaust.

i like the exhaust. i thought it would be more aggressive sounding especially since i have a k&n CAI. it has a nice rumble though. the guys at flowmaster said that the louder 2 chamber mufflers were not rated for the Hp of the 5.7 and that performance wise its best to go with the 50 series 3 chamber that comes with the kit. overall i enjoy it though. fuel mileage has greatly improved. my tundra already had plenty of power and the flowmaster has only added to it.

I had the system all layed out, and got to looking it over, When I started to realize that I don't really know where to run the Driver side unless I remove the spare tire. The other obsticle is the anti-slip/traction control unit that is between the rear end and the fuel tank. I will remove the spare tire I guess because I don't have much choice.

Nice sound, good power, good instructions. Only complaint is that the clamps really need to be torqued down - I broke a socket. A 1/2" socket set with a long handled wrench is pretty much a must, I recommend welding.
