Exhaust silencer performance

Wats up guys, wanted to ask a question. I've been trying to research if exhaust silencers effect performance. I cant get a clear answer through web searching but I wanted to get a sense of what you guys think? I got the z tuned last week with a musarri exhaust without silencer, chimera intake and Aracer ECU and I'm experimenting riding with it in and out. Only sure way to know is to go back to the dyno and compare but I dont have the funds for that at the moment. Any input is appreciated.

Considering most silencers are just creating a restriction to reduce noise id say it will affect power. How much it depends on what mods. I know my z made the same power with the rs2 with or without the silencer on a 143 kit but with the 165 kit the top end lost a 1/2hp.

I hope this helps

My experience with the Hindle is it seems to have a little better torque down low with the db killer. Noise is much more reasonable. Top end is still good. After going back and forth I opted to use the db killer. The hooligan in me still wants to pull the plug as the decel noise sounds like a Ducati.

From what I hear, it seems the silencer may help the low to mid range torque. I'm gonna experiment a bit but considering I have a slighter bigger rear tire and a 15T front sprocket I gotta snag as much torque as possible, thx guys
