Slip on pipe vs. Full exhaust system

[vansmack]

Hey, whats up everyone, had a question about pipes, I just took off my Yoshimura slip on and im putting on a douglas full system I was wondering about how much more power I should get? I also have a Dyna ignition. The bike is a Z-400. Thanks

i am not sure but i think the full system will add more top end then a slip on and work much better with a modded engine.

yeah full systems work better with modded engines
