MBRP sells 3 grades when buying, aluminized, and two grades of Stainless Steel. Aluminzed is cheaper but won't last too long in salt spray. I went with the mid grade SS and have had happy results with one year of salt blasting under my belt. I got my set up from elite diesel, great people to deal with and didn't take long to arrive. I welded mine but the clamps are heavy duty stainless steel. I originally went with the straight rolled lip tip and it sucked! I just bought and installed the the angled mitered tip, fit and finish is worth the extra bucks, plus you get the MBRP logo right on the tip.
My buddy also has a 6.4 and piped it, don't remember the make but it sounds good from idle to about 1,500 but after that it sounds like crap. This is where MBRP shines, you get the nice wet fart sound in the higher RPM's. I have always had great luck with MBRP, I got two sleds with their silencers on them and love it
Have fun and make sure when you install the muffler you have the direction the right way, better sound and flow. You will get that famous whistle.
