LB7 MBRP 5" Aluminum Downpipe-Back Exhaust

MBRP LB7 5" Aluminum Exhaust

MBRP's 5" exhaust system for the LB7 is our favorite 5-inch exhaust on the market. Made out of aluminized steel, without a muffler this exhaust will offer maximum performance and temp reduction without the drone you would get from a stainless steel exhaust.

There is no such thing as too big of an exhaust for a diesel truck - if you want maximum performance on a budget this is the right exhaust out there. If you aren't running an upgraded turbo then you can save some money and stick with a 4" exhaust, but if you want the biggest and best then this is it.

We highly recommend upgrading the downpipe alongside adding this exhaust system. Getting a larger 5" exhaust won't really matter if you're still running the small, crushed factory downpipe. We recommend using the 3" PPE Downpipe which is a direct bolt-up to this MBRP exhaust and the best value on the market.

Exhaust Upgrade Benefits

When you combine this exhaust with an upgraded downpipe you can see:

• -30whp and 60wtq power gains
• -200+ degree EGT reductions
• -Virtually zero exhaust backpressure
• -Faster turbo spool and increased turbo efficiency
• -Louder exhaust tone
