I've seen/heard both, and have personal experience with Yoshi, and I'll go ahead and throw this down: From my two Yoshi off-road product experiences, their quality and ridiculous customer service is second to none. Every time a repack my ATV pipe, I discover another little nougat of engineering magic they tossed in there. Just for me. They were like, "Man, if we do this little trick, some kid is going to see it and be like 'SWEET. That junk is TIGHT and DONE RIGHT!' " Which is precisely what I do every time. I find D&D's annoying, but I'm a 20 year old geezer, so factor that in.

There's my two cents.

 

if 20 makes you old these days...

 

CBR 600F2 - I had a Yoshi shorty, pretty darn loud and sounded decent. Kind of bubbly any time I would let off the gas. Just bought a Vance % Heines to replace it.
