Traditional Exhaust Stack

Straight Cut

Agressive in your face look

Aggression is here. As in-your-face as possible the Straight Cut stack is here to stand its ground, looking down on all else. Rising from beneath the guards like a pillar, Straight Cut stacks always seem to go much higher than they really are. Without doubt the Straight Cut makes an impression from every angle... A fearless, torquey stack...it’s made for any journey….think long straight roads, brilliant sunsets and endless cruising.
