Sparks pipes are awesome and are supposed to be one of the best, if not the best. They are loud, but not as loud as some other pipes out there. They are above legal limit, and do not come with a quiet core option.

If you want more low-end power it is recommended to go with an X-4 pipe.

Rule of thumb: X6 for Modifyed motors, mid-top power
X4 for mostly stock motors, Low end torque

Remember, Curtis Sparks Pipes are race pipes. they are fairly loud, about like an HMF, maybe a little louder. The only option is a S/A.

I see you have a 250ex...Im pretty sure they only have one exhaust for them and not your choice of x-4 x-5 or x-6...

They were tested at 95DB for the 250...
