Hate to beat a dead horse, just wanted some opinions, im thinking of buying a Curtis Sparks X-6.

 

Back when shoot outs were done on this quad, the X-6 had the most power. It also has one of the loudest db readings, oh and the highest price tag.

I have an HMF on my 440 stroker. It is a great pipe for the price and is fairly quiet with the Quiet core installed.

 

thanks
