    Received the package fast and it was a direct fit. Just had to modify the heat shield a little to get it to fit back on.

    If you're not ready for a whole set of manifolds and up pipes, this is the next best thing. Some people have said they needed to remove some left over flashing from the inside but mine was perfect. I messed up trying to reshape the oem heat shield so I ended up just painting the manifold with high heat ceramic header paint. Fit perfect and the only thing wrong was BD didn't send a plug for the 1/4 fitting. Can't really feel a difference power wise but I'm sure the engine is running better after seeing how pinched the stock manifold was.

    Took less than 2 hours to install, taking my time. I can't believe how pinched down the stock manifold is. Since the steering shaft needs to be disconnected, it is a good opportunity to replace the steering column bearing too. I installed this with an EGR Delete, so not sure what performance I gained from this alone, but between the 2 it was well worth the time & money to do!

    Worked great for getting my EGT probe in without any issues plus replace that bend in the stock design, nice forge piece in that there were no burs or slag to knock off before install.
