Improve Fuel economy, reduce EGT's and make your Duramax Diesel sound better with this Max-Flow 3" Downpipe. Upgrade from the restrictive stock downpipe and allow your turbo to work to its full potential with 20% greater flow over the stock unit. Gains up to +25 HP dependent upon supporting modifications and tuning. The included heat wrap will help retain heat reducing EGT's while towing heavy loads. The Max-Flow downpipe will increase throttle response because of the smoother flow out of the turbo causing it to spool sooner.
All Downpipes come wrapped with titanium woven heat wrap and two stainless steel hose clamps.
