what do u think of this

[cals400ex]

my buddy has this pipe on his built motor and it runs really strong. it doesn't rev quite as high as my buddies hmf and not as high as my x-6. if i had to do it again, i wouldn't get the x-6. i would highly consider the full hmf. the lte seems to make great power too from what i hear. the new pulsecharger that isn't quite out yet seems to be really interesting too.

Waste of money, just get the X-6.

Read Spark's suggestion on the X-6 on his website. He said the X-6 does better than the X-4 all-around and is exsplosive on top end. I've had both on a stock motor and the X-4 SUCKED!! Also, make damn sure you pay the extra pennies to get the stainless system b/c their ceramic coating is a joke. I've had 6 of their pipes, 5 were ceramic, and they rusted to hell in a month or so. And befroe you ask, my bike gets a extensive washing after every ride! So that's not the problem. Someone who's a Sparks dealer told me that the ceramic coating is actually not ceramic, but a type of powder coating that's not going to hold up to high temps for very long. Jet Hot is the only type of coating that holds up. The stainless X-6 held up great however. It's deff worth the extra money if a spark arrestor is not required for your type of riding. One is available for the X-6 though.

Same all-around as the X-4, but with more top end!;)
