Im wondering what the loudest yfz450 exhaust is. Its for my yfz on the track.

 

If all you want is loud, cut the end of the stock pipe off [img]i/expressions/face-icon-small-tongue.gif[/img]
If you want performance, then maybe a Rossier pipe. I hear they are very good

 

i know the TC pipe is quite loud...
but loud doesnt always mean more power, and what you want is power.

 

I chopped my stocker to 6 1/2 inches - with no baffles and the end cap on, the thing is loud, and I have just as much power (if not more) than people with $400 full systems. The stock headpipe is plenty big enough - so I don't see any need to buy anything as far as exhaust goes. If you want to save some money, just do what I did.....

That's a cool idea.

 

does it hurt ur quad to take the baffels out??

 

The tc pipe is LOUD. I have heard numbers of around 110db.
