Through initial testing both with the WSRD Exhaust System and WSRD Tune files we saw the following power production from the stock tune file;
~ Stock Tune: 213 Hub Horsepower | 240 Crank Horsepower
And, through the development/design of the WSRD Exhaust System we saw the following power production;
~ Stock Tune + WSRD Turbo-Back Exhaust System: 225 Hub Horsepower - 250 Crank Horsepower

A 10-12 HP increase over the stock exhaust! A great addition to your machine with or without WSRD's tuning solutions!
Hub to crankshaft power production is reviewed and calculated as an 11% correction factor.

The WSRD Dual Exit System is designed with a motorsports-like feel in mind. Both options sounds great, while the carbon and burnt tips add a very nice flare to the rear of your machine!
This is a full 3" stainless construction with a v-band flange install for end user simplicity.
