Available in hi-temp paint, ceramic coated, or new, polished stainless finish. All flanges are heavy-gauge steel, jig drilled, and ground for a tight gas seal. The unique Bosal Brospeed Flex Joint absorbs engine movement to prevent stress on the exhaust system connections. Stainless systems feature 16 gauge single wrap shells. All systems and mufflers are finished off with Bosal Brospeed's chrome tip featuring double-plated chrome, a true rolled edge, and a stainless steel insert for longer life.
Stainless systems have a full stainless tip.
When an engine's exhaust valve opens, the escaping gases create a pressure wave which travels at the speed of sound down the exhaust system. A tuned exhaust system is engineered to take advantage of this wave action. As the exhaust gases are pulled out faster, the inlet charge is drawn in faster, increasing volumetric efficiency and engine power. This effect can be harnessed in a multi-cylinder engine so that the exhaust pulse of one cylinder enhances the intake of another.
