Description
 
No Compromise, High Performance Street Exhaust System!

What sets CB's Pro-Flow Street system apart from the competition? It's our 1 1/2" Full Merged Header matched with our #3678 High Performance Flanged Heater Boxes.

Manufactured from heavy gauge 1 1/2" tubing and equipped with header flanges to provide 20% more flow than stock heater boxes. They bolt right on to all T-1 & T-2 1600cc based engines. Standard or aftermarket heater channel may be used.

To complete the system we include a DYNOMAX Super Turbo all-aluminized muffler for great looks and long-lasting performance. Patented flow directors eliminate turbulence, large diameter internal tubes improve exhaust flow / reduce back-pressure, and fiberglass matting absorbs unwanted interior resonance.

You'll love the Mellow Rumble and gain in horsepower!

Also available: Cable lever arms and hardware kit.

Exhaust Header and Muffler are MADE IN THE USA, Heater Boxes are not.
