Where I can find a C-Sparks X-6 Ceramic Exaust System???

[ErthXINGon400cc]

Does anyone know what website I can buy a Curtis Sparks X-6 Ceramic exaust system? I have stock jetting, what should I take my jets up to if I get the X-6 exaust system? Also I'm thinkning of buying a Weisco 440 kit, would I have to buy a new carb if I get the 440 kit? If so what kind should I get? Please let me know, thanks!

Oh yeah I almost forgot to mention that I saw on one thread that I could buy a X-6 exaust system from C&D racing but I can't find it on there. Can someone lead me in the right place? Please let me know, thanks!

try going to C&D's section and asking them about the parts you want. they will respond with a pm and get ya squared away:)

You can also go to sparksracing.com and click on 400ex then on motor and they have it for 489$.

with jet the pipe, mine ran good with a 155 mainjet in. most recommend using a bigger jet, but theirs won't be as fast either. you may need up to a 158 in the winter months. sparks actually recommends a 152, but i wanted to be on the safe side and not run lean. your stock carb will do just fine even with a built motor, however an aftermarket one like the fcr will perform better.

i forgot to mention, call up C&D and they will be able to get that pipe for you. they also have better prices than sparks on the x-6.

There is a shop on ebay called Woodward Specialties. Has the sparks X6 in stock on the East coast and clutch kits too! Think they are physically located in PA. :)

We sell the sparks pipes. Our website only has a fraction of what we sell on it. Remember we are a full service shop so we sell almost everything and also do full race engine building. :)
