It's definitely louder than the yoshi, but it was a lower tone...Sounds more pissed off without sounding annoyingly loud. But when I ride in front of him I can hear his exhaust when he rolls on the throttle over mine...

 

Go with the LOR.. Its loud but has a great tone to it. Would'nt trade mine for any pipe out there.

 

Lots of people think the Yoshi is real quiet because they don't realize there's a silencer insert already installed out of the box. Two screws and pop it out - now you more/less have a straight pipe. I can get a sound clip after I finish my sprocket/chain install.

 

My Erion sounds pretty sweet. It screams when you get on the throttle but when your not on it hard it has a nice rumble to it

 

The D&D and LOR260 are both louder then hell, annoying to say the least.

 

Who can personally vouch for a devil pipe??
