Great purchase for the 5.7 Tundra by Fire hawk, January 24, 2014

Ease of Use/Installation:
Overall Rating:

Bought this system for my 2010 Tundra with the 5.7 V8. Let me tell you Wow does it feel good to hit the gas now! The install was slick and easy only taking about an hour fitting into all stock hangers. The dual side exits with the 4 inch stainless tips look great. I recommend at least tack welding all joints just for security reasons on top of using all clamps. Its got a deep throaty sound all the way up trough the rpms not sounding like a cheap tin can. This system by far is worth the money but does NOT improve the torque thats a sales flaw. BUT its one heck of a look and great sound I highly recommend.
