I was wondering between the white brothers and sparks. which is the better one for my quad. And whitecarb should i run, i was thinking edlebrock. Thanks

 

what kind of quad do you have[img]i/expressions/face-icon-small-confused.gif[/img]

 

My buddy has a 400ex and he put a fatboy 4 on it. It really made his machine move. He also did the K & N air filter and bumped up two jet sizes. He is in the process of doing the edlebrock carb from duncan. I was reaaly impressed and highly recommend it

 

i run a 400ex

 

I had a Sparks X4 complete system on my 400EX. It pulled like mad, but was too loud for my tastes. I put my stock headpipe on, after grinding the welds down, and put on a Yoshi slip on. It's a lot quieter, but doesn't pull nearly as hard, but I'm very happy with the noise/power exchange. The X4 is for sale.

 

I'm Guardog's buddy and I have to agree with him that the Duncan Fat Boy 4 fipe and silencer are awesome. I put on a K&N air filter and new jetting. I also put on the white brothers Rev Kit. It was an incredible increase in power. I am going with the Qwiksilver Carb. Everything that I have read is good. I think that you cannot go wrong. Good Luck. Let me know if you need any help.
