Damn, i've always wondered where I could buy these.
Johnson Rod - Always be ready with a spare.
Muffler Bearing (goes well with Kent's Tailgunner exhaust)
Piston Return Spring - For snappier engine performance
Cross-Drilled Brake Lines - You thought cross-drilled *rotors* improved performance? Try these!
Engine Oil Bypass Kit - Prevent premature breakdown of that expensive synthetic oil!
O-Pipe - dual exhaust model
O-Pipe - single exhaust model
Maybe some of the more adventurous members could try some of these out and let us know how they improve performance... Coolio?
