Now at Summit Racing: CARB-Approved Turbo Downpipes from Diamond Eye Performance

If you live in a state with regular emissions testing, upgrading or repairing your diesel engine can be a harrowing experience. Diamond Eye Performance’s CARB-Approved Turbo Downpipes are a bit of good news. The downpipes are made from high quality aluminized steel or stainless steel, and feature mandrel bends for improved flow over stock. The flanges are CNC machined to ensure an OE fit.

But the best feature is the CARB E.O. number D-778, which will allow you to install one of these downpipes on your stock vehicle without any legal entanglements.

Diamond Eye Performance has six new CARB-approved Turbo Downpipes for the following vehicles.
