    Awsome gains! Can really feel the Increase in torque and power! especially in the lower to mid range. Install wasn't too bad. I wish I had taken it to a shop though. Because I dont weld. :)

    I've been dealing with problems and leaks the past 3 weeks, bc I thaught I could handle the Install. But I was wrong!!! I got one more fix this weekend and I should be good! I hope!:)

    I bought a set for my '03 thinking I would install myself. In the end, I had the dealer do it and happy that I did. Never had a problem with them in 130,000 miles. Added power? You get a few extra hp's and better sounding exhaust but it won't be a race truck.

    Looking back, I ran at about 16 mpg but many other mods influenced that. I doubt it was significant either way.

    I have had my TRD headers on for about 8 years now and noticed a few things.
    1st off great sounding exhaust... did not think about it, but was a nice add on
    2nd, increased gas mileage. I get 20mpg on my v6. I do have a SC on it too, so plenty of power all around.

    I would buy them again for suire...
