no no no... the yoshi by far is the BEST! It looks good, you get to keep all the original heat shields, gives the best overall gains, and its loud as hell, louder than big gun, ct, both white bros, fmf, and all the others. I've raced them all and have not been beat by another raptor! Its a little pricey, but if you want to haul a$$ like me you better get the yoshi!!

 

There is a pay site that has a few pipes they have tried. Its only 3$ and isn't a bad site. ATVtesting.com They have dBs limits on the G-YTR pipe here.

 

pro circuit ... full system with or with out quiet core rocks..i feel it has more useable power than the graydon full system..the silencer quality and craftsmanship is far superior to the graybon silencer,,but i like the look of the graydon head pipe.but the procircuit is my favorite.

 

NotuRaptor,

Thank you for all of you information. I might consider the GYTR exhaust with the other modifications that you made as well. To be honest with you, I'm knod of reluctant to drilling holes in my air box and removing the snorkel. I may try it. If you say that the exhaust makes a big difference over stock form, then I will put the 13 tooth sproket on.

Thank you for all of your information!
