The word you are looking for is Loud. With no core or packing I'll almost say for sure that you'll be over 99dbs with a full system.

If i didn't have a core or any packing, I would not even race. They are there for a reason..

I dont run the QC in my Yoshi. My 440 is pretty quiet compared to all the 450 bikes that run at the track...so they dont give me a hard time.

No core, and no packing will make it run like garbage anyways.


I have an Nmotion full exhaust on my 450, so everything seems quiet now haha.

First of all forgive my spelling.I did repack my muffler and it is not as( loud) as a sparks but still pretty darn load.I guess i will just have to cross my fingers.Keep the rubber side down because it is time to go racing.Pretty some i will be able to race the old man class 40 plus, thanks for the info .Full pin
