GP Slip On Exhaust for Triumph Street Twin / Street Cup

Triumph Street Twin & Street Cup Slip-On Exhaust British Customs’ GP Slip On Exhaust is a unique choice for your Triumph, providing an updated alternative to the typical classic style exhausts available for Triumphs while delivering real performance benefits. The GP exhaust is the lightest British Customs stainless steel exhaust system, manufactured from lighter 20 gauge stainless steel (rather than 18 gauge used in our other exhausts) and updated internally with our new race core instead of the heavier, louvered cores used in the Predator Pro and Sleeper Pro Slip On Exhausts. The perforated baffle core is wrapped in stainless steel packing and allows for increased air flow, less weight, and a higher pitch performance exhaust sound. Each segment of this stainless steel exhaust system is rolled, hand shaped, fitted, and brushed in Gardena CA, manufactured with care by our expert craftsmen who leave the welds exposed to preserve and feature the craftsmanship poured into it.
