Luckily for you, I know a "FLO PRO 4″ DOWNPIPE BACK NO MUFFLER" exhaust system is the best exhaust for that 6.7 powerstroke straight pipe engine. Everything went well during install, works as it should. You will need some new hardware but other than that it is good quality and got all that dpf crap off my truck.

That's why when you buy a Banks system, you get just what you need—no more, no less—and 6.7 powerstroke straight pipe you never pay for what you don't need. Nothing looks better or lasts longer than stainless steel. The aluminized steel has a coating when scratched off will rust. But stainless steel does cost more than aluminized steel, ultimately if you can live with a rusty then you can save yourself a few bucks at checkout. Some cutting may be required to fit shorter wheelbase bed/cab configurations.

We suggest the stainless upgrade if you regularly operate your truck on salted winter roads. Diesel Particulate Filters (DPF) are cleaned through regeneration in which scorching exhaust gas temperatures can last up to 20 minutes while driving. The Monster Exhaust massive over sized tip is aimed out to the side of the truck. Crafted from 16 gauge heavy-duty aluminized steel, Armor Lite has the same fitment and performance as T304 and T409 products. DRYING - After rinsing, gently shake off excess water and allow it to dry naturally. Re-install the filter onto the intake system, airbox, or custom assembly once it is dry or just slightly damp.
