I was waiting for that... LOL

 

Muzzy's are good. I have a friend who has one, its not too loud. But one thing I have noticed, the size of the engine will make the difference on how loud a muzzy is. The ZX-9 Ninji isn't very loud, but the ZX-6R 600 is much louder. I run with a Two Bros. and its plenty loud for me. And depending on how many rpm's your riding at makes the difference.

 

Yosh rs 3 series is pretty quiet. i had one(full system) but took it off. it was tooo quiet for me.

 

Acropovic is barely louder then stock and generally bosts the best improvement in HP plus the thing weighs next to nothing

 

The Jardine RT-1 pipe I have is with the street baffle (can get with race baffle which is louder) that is actually kinda quite. Putting around town wthout getting noticed is a piece of cake. Hell, even the guys who ride behind me can barelyhear it!
But once you get on it , be prepared 'cause it wakes up over 7k.
I've gotten so used to it that I'm afraid the Two Bros. I'm thinking of getting will be too loud cruising around.
Great price too, undercuts the Yoshi by about $100.

 

yea i was wondering about this too. i dont necessarily want a loud exhaust, the main thing i want is a deep smooth rumble i guess. just like with my truck id rather have a deep roar, then the loud clack of glass pax (which my friend had on a 78 dodge dart, haha)
but which one do you guys think would be best for the deep smooth sound that im looking for?

 

+1 - Jardine RT-1 - nice sound - not loud, but there. - Get on it and you hear it though =-)
