The GP Exhaust was inspired by custom racing bikes we'd seen over the years. The goal of the GP was to offer a werkes looking pipe, with exposed TIG welds, and henckel cut patterns while increasing the performance of your Triumph Motorcycle. 

The pipe is 100% stainless steel construction and weighs just 2.5lbs per muffler. The pipes feature a perforated core baffle for maximum power. All internals are stainless steel as well. The mounting brackets are rubber mounted to isolate engine vibration transfer to the rider and reduce bracket fatigue. Please note: the GP Slip On Exhaust will not work with center stand. 

Included Components

The GP Slip On Exhaust is manufactured from 304 Stainless Steel and includes all stainless steel exhaust clamps and mounting hardware. 

Included Components:

  • GP Exhausts (pair)
  • Stainless Steel mounting hardware
  • Exhaust Gaskets (Bonneville T100/T120 models only)

Installation Process

The GP Slip On Exhaust installs in under an hour with common tools. Simply remove the factory exhaust and bolt on the GP. Please note: These pipes WILL NOT work with a centerstand. 

Estimated Install Time - 30-60 minutes

Not Available for Sale in State of California

Each state has its own emissions and inspection requirements.  In California, this is managed by the Air Resources Board (CARB for short).  CARB has determined that certain aftermarket motorcycle parts are not legal for sale or highway use in the state of California. Items subject to this determination include certain exhausts, fuel controllers, and other parts that might affect a vehicle's emissions.

British Customs has determined to the best of its ability which items are CARB approved and which items are not - items that are not CARB approved are not able to be shipped to addresses in California or used for on-road use in California. 

Items that are not CARB approved may still be utilized in the state of California, provided that they are not used on a public road (i.e. only used on a closed course or offroad).  At this time, British Customs cannot verify if a product is used for closed circuit or off-road use and cannot ship to addresses in California.  

For more information, please refer to the CARB's information page.
