Product Description

While the search for more power for your LLY, LBZ or LMM Duramax powered vehicle usually leads you down the path of exhaust, intake and tuner, one item that is often overlooked is the factory restrictive turbo direct pipe. MBRP has addressed this restrictive component of the factory exhaust with our new turbo direct pipe replacement that mounts between your factory turbo and your exhaust system. Featuring full 16 gauge mandrel bent tubing for maximum flow, and an extremely durable high temperature ceramic coating, these pipes deepen the sound of your V8 diesel engine while lowering EGT's and providing quicker throttle response.

Longhorn Fab Shop Note:  This is one of those parts that are a must have!  It lowers EGTs and reduces turbo lag.  When you pull the stock downpipe off you'll be amazed that it flows anything at all compared to this huge downpipe with smooth bends and large diameter!  This will allow you to get to full power faster and stay in it longer.  Don't be left behind by people that have already purchased one of these and installed it on their truck!

    I already had 4" MBRP straight pipes which were awesome, and this downpipe made it sound and feel better. Then i paired it with a S&B turbo mouthpiece and WOW! Great product. Easy install.

    Install was easy just took a few hours 2 heads and patience. Throttle response and torque where the two big differences I felt immediately. Made the exhaust sound much deeper in a good way. Overall well worth the time and money thanks again longhorn

    The fitment was really good until it came to connecting the exhaust...Both were MBRP, so not sure which was the issue. We had to cut the flange off of the exhaust side, change the angle, and weld it back together. Looking at it side by side with the factory piece, I suspect the exhaust to be the problem. Other than that, it looks like it will flow circles around the factory pipe. Very pleased

    Great product.
    Removal of OEM down pipe was not so fun.
    Install of the MBRP was easy! Popped right into the turbo outlet.
    Sounds great!

    Great piece for any duramax owner, love the new sound at full throttle, better throttle response, haven't had time to check fuel milage, but highly recommended! A little bit to instal but follow instructions and you will be fine. Only problem is that I should have bought this a long time ago.
