I was trail riding the other day and stopped to talk to a guy. In the article there was a pipe from Yosimura that was like 43 horse and was quiet also. Is this true? I am looking for a quiet pipe that gives a horsepower boost. Which Yosi pipe was it? They have a couple different models. I have a GYTR now and its too loud. I knew I shouldent have let me subscription run out!

 

The CT Sonic pipe made the most power out of 12 different systems at 48.6 HP. However it was the heaviest and one of the loudest at 103 db. The Yoshimura Tec-SA came in 4th at 46.2 HP and was the quietest at 100 db.
There's your choice.

 

What is the decibal level with the stock pipe?

 

The stock pipe is 92db according to DW.
I got the Sparks, Kinda loud DW said 102db but I kinda messed with it & it may be louder than that but it's a good loud! I don't have to worry about noise restrictions though. [img]i/expressions/face-icon-small-happy.gif[/img] [img]i/expressions/face-icon-small-cool.gif[/img]

 

Im just going to keep my gytr. That guy told me the yosi was only 2 decibals louder than stock. 100db-92db=2? he must not be able to count. Oh well it sounded to good to be true.
