i still have stock exhaust on my bike... a local guy has taken out the cat

out the pipes and tell me that you get 25 % more sound...could that be true...

i didnt hear it... i know, the engine will be cooler for sure... thanks for your help...

 

I don't know about that 25% more sound. I noticed more sound, but then again, the entire exhaust was changed. There should be some increase in sound output, as cats are extremely restrictive.
