Unexpected Upgrades: A Couple Tips

MBRP Gets the Hot Air Out!

When we last updated you on Mike Sutton’s ’18 Dodge Ram 3500 Mega Cab, the performance upgrades had begun with a programmer to fine-tune every computer setting possible, a throttle booster to provide a pick-me-up, and an intake to help bring in more air for the diesel beast. It’s no secret that to get the most out of your diesel engine, you need a supply of cool, clean air. You can get fresh air in, but you must also usher the hot air out.
The MBRP Inc. Performance Exhaust going on Mike’s truck is specific to this model, but the company carries options for many years, makes, and models. This version, the S6167AL, is a 4-inch filter-back exhaust with dual outlets on a single side with an aluminized finish. Mike chose to use the black T5051 5-inch angled exhaust tips with a rolled end. This setup is capable of dropping exhaust gas temperature by up to 200 degrees Fahrenheit, and, when it’s combined with the previous products installed, it encourages the 6.7L Cummins to perform well no matter what driving/towing conditions put it to the test. Take a look at our quick install, from bone-stock to where we are today.

Photo 4/17   |   The MBRP Inc. S6167AL kit consists of an extension pipe, Y-pipe, front tailpipe, rear tailpipe, two exhaust tips, and four 4-inch clamps.
Photo 5/17   |   Here’s the stock exhaust from the factory. It’s functional, but not aesthetically pleasing. This kit will be a huge upgrade in function and looks.
Photo 6/17   |   The first step is to loosen the clamp just past the particulate filter.
Photo 7/17   |   Using a 5/8-inch socket and air ratchet, the clamp is loosened. A penetrating lubricant may need to be used depending on how tight the nut is.
Photo 8/17   |   The tailpipe hangers are removed from the OEM rubber insulator; the insulator will be reused with the new exhaust.
Photo 9/17   |   Our factory exhaust was on pretty tight, so a few taps with a mallet or other hammer loosens it enough to pull it apart.
Photo 10/17   |   The full section from the particulate filter back is removed and discarded. None of this will be needed again.
Photo 11/17   |   The Y-pipe is fitted into the rubber insulator to start the installation.
Photo 12/17   |   The extension pipe is then fitted onto both the Y-pipe and the particulate filter outlet and is completely tight on both ends. The Y-pipe needed to be temporarily forced toward the rear of the truck just enough to fit both in.
Photo 13/17   |   The rear tailpipe is fitted onto the upper outlet of the Y-pipe followed by the front. After aligning them, the 4-inch clamps are tightened.
Photo 14/17   |   We used a floor jack and 4-inch wood block to get the exhaust sitting right where we wanted it after test-fitting the exhaust tips. The clamps are tightened when everything lines up to our satisfaction.
Photo 15/17   |   MBRP recommends spot-welding at each joint while the clamps are fully tight—not for fitment, but to reduce potential vibration, which could cause pieces to come loose and detach.
Photo 16/17   |   Mike chose the black tips to finish off the exhaust. They look good, but even better is that the overall diesel performance upgrade will be noticeable.
Photo 17/17   |   We’ve come a long way in a short time with this new Ram, but we still have a few more things to do, so stay tuned to see what we have in store. Check out mbrp.com to see what’s available for your truck and check out the full Ram build at truckin.com.
