curtis sparks x4 or x6

[81 clark racing]

it says good for stock motors tight tracks and the woods. will it also work good if i decide later on to bore my 400ex and do high comp piston and all that? or am i better off getting the x-6, but then will that work good with my 400ex stock motor? also compared to the procircuit T-4 is it louder? thanxs

[honda300EXtreme]

id get the x-6 because if you decide to do motor mods you will still have the right exhaust, aout being louder i dont know, but def, get the sparks

[trx400EXtreme]

i think (dont quote me) they are both pretty close to the same db level.

[04exking]

I believe that they are pretty close in sound but the X6 is known to be louder.

Get the X6 regardless if you have a stock motor or not, I have it and it's great, although my motor is not stock :D

Anyway, sparks is WAY louder than any pipe i've heard so far (on a 400ex) other than a shorty pipe. Make sure you get the ceramic coating, and if you want, the big core. I love my pipe, I wouldn't get rid of it for nothing, I noticed GREAT gains in top-end, and some torque. And the turn down end cap is awesome, just looking at the dirt when your sitting still and you see dust flying is awesome :blah: and the echo of the pipe kicks *** too.

do they make a quiet core insert for the sparks?

[81 clark racing]

yup

[400eXr1d3rZ]

Supertrapp makes a disk-type endcap for sparks I believe.

EDIT: I went to Sparks website and they do not advertise a quiet core, so I'm assuming they don't make one. But they have a "quiet modular tip" and a spark arrestor.

If you want to keep the noise down, just remember to keep the muffler packed.

[81 clark racing]

is it bad if you dont run a spark arrestor? will it cause damage to your motor

[250rstar]

No damage will be done to your motor if you run with out the SA. It's just there to catch hot pieces of metal coming out the pipe that may start a fire in the woods. It also quiets the pipe, but by very little.

[81 clark racing]

thats what i thought but people always told me before to never run a quad with out the sa because it would eventually burn up you vavles and what not. anyone no if the sparks x6 system comes with a sa?

[250rstar]

I think you have to buy the SA seperate with curtis sparks. It only cost like 20bucks. Don't quote me on it. I'm looking to buy a 400ex and will most likely go with the CS pipe. I've heard a couple of the pipes on different bikes and I love the sound of it. If that helps you any.

sa is 14.95 from cs
