Direct fit for my Hummer H3. Easy to install, and built very solid. I previously had a Wagner aftermarket brand one on there and it was thin junk compared to this one. Think of this as being more of a heavy duty build. Since it deletes the resonator, it definitely has more of a throaty sound to it now!
