LOOKING TO BUY A PIPE FOR MY 2005 RAPTOR 660. I AM ASKING YOU GUYS FOR HELP, WHICH IS THE BEST PIPE (OVERALL FOR THE MONEY) FOR MY RAPTOR? PLEASE HELP ME OUT. THANKS IN ADVANCE...

 

I have a Pro Circuit T4 on mine. I would recommend it.

 

I like my full yoshimura exhaust for under $400

 

I also have Pro Circuit T4 and am very happy with results. Local ATV shop said dyno test come back with Pro Circuit getting one of the best hp gains. I think Yoshi was the other, buy I've heard there a bit loud and I'm not really into the loudest. Also, no need to get full system unless your going to do interior engine work....fyi....

 

I ran a Big Gun full system on my bike with GYTR jet kit and pro-flow K&N. The power was good, but it as more a mid range/top end pipe. I rebuilt the engine this winter and went with an LRD Pro 4R, and this pipe is much better. The can is longer, and the header pipe expands to a much larger diameter than stock. For only $420, this pipe is great.

 

bakers!!!!!!

 

I would either get the LRD or the yoshi, which is what I have. Both are great fit/finish at a good price.

 

Close, but not quite. Try the name again.[img]i/expressions/face-icon-small-wink.gif[/img]

Big Gun and Pro Circuit are mediocre at best, yoshi is and has been for some time, the best bang for your buck. The only exhausts that perform better on the 660 cost between 500-800 dollars.

 

barkers!!!

 

No one mentioned HMF yet? Then let me be the first to recommend the true best bang for the buck exhaust..................HMF!
