Installed MBPR 4" turback last night. PITA removing the old one and I think the worst was getting the OEM exhaust supports off the exhaust in a re-useable condition. Once all was removed the installation of the new was easy. I can't say the sound is much different and am going to straight pipe it. I bought P/N#6212409. I had the original pipe that I knocked the CAT out of and already had some turbo whine. Good to know- I have an F-350 super or ext. cab. There is a section of pipe that is not used in the kit and once 2" is cut-off and then flared, the resonator can be removed and re-installed with ease. This piece of pipe replaces the resonator by just loosening a couple clamps.

Nice work! I am sure it looks pretty good, and flows nicely
