        Will this x pipe pass inspection in Texas?

        • Hey ML, Every state is different with their restrictions, your best bet would be to ask your local shop or the one that would put it on to guarantee that it'll pass. Most states will pass as long as it has cats and this has them so it is highly likely it will. But to be safe you should always check before installation

        Is this DOT legal in CA?

        • This X-pipe is not DOT legal in California as it does not have a CARB EO number that would clear it of California's SMOG check.

            Install was what we expected, sound great, feel added performance with complete magnaflow full exhaust. Shorty headers, xpipe, competition cat back.

            Fit like a glove!

            Kit is very good quality. Fit is fantastic. But the one thing that they don't tell you is you need a tune. I drove a few miles and the check engine light came on. Good thing I had ordered my Bama tune before I got the kit since it took a few weeks to get a new file. With the new tune light is out and runs fine. In normal driving car is still kinda quiet but above 4,000 it makes some noise. The car has lost some low end torque.

            These make a great addition to Short tube Headers.

            They sound great but removing the stock cats can be quite painful due to the limited area to work with. I just wish the studs were of grade 8 material. These studs seems to be made of a low quality metal and the threads seem to damage easily in transit. I was afraid to really crank down on them for fear of snapping them off. The studs were also too long. I has a hard time threading the nuts over them, especially with my Kooks Short tubes. I was also missing one of the Magnaflow brand cat to header flange gaskets. I just bought 2 original Ford OEM gaskets and 4 new OEM hardened exhaust nuts to complete the install. For almost a grand this kit should have came with 4 grade 8 studs, 2 Ford OEM gaskets, and 4 Ford OEM hardened exhaust nuts. It should have included better packaging to protect the converter studs. Overall it looks great, sounds great, but the little stuff is what kills it for me.

            Very Satisfying Product

            Easy install. Take your time to insure your tailpipes stay lined up!
