Performance and looks is great. The package comes with everything you will need. However, the X pipe fitment leaves something to be desired. The X pipe fits in such a way that it dips or hangs lower than the rest of the exhaust. My local exhaust shop tried flipping it every way concievable and at best it hangs. Since my car is lowered it scrubs on everything. Looks like I will toss it out and build a custom X pipe.

They got them to me very fast and witb no problems what so ever. Did the installation my self and it was super easy to do. They are built exactly right for the vehical you choose. It makes the sound much deeper and more gutsy, plus the added MPG is great.
