I know a couple have been asked a lot, but I haven't heard anything about some of the brands im curious about.
Im looking for a new pipe, but I just hear about the FMF and White Brothers. Has anyone tried out the Sparks?

Sparks Racing 300EX / 250X ceramic complete exhaust system X-6 w/ spark arrestor
DMC Exhaust System, Honda TRX300EX 93-04 "Alien"
Hetrick Exhaust
Or Yoshimi(SP?) Titanium Slip on

Basiclly what im looking for is a exhaust that will do best for over a 400cc engine.

Carb wise I always hear about using 400ex carbs.
Has anyone tried a Edelbrock carb before?
Does anyone know any sites that have carbs. Or can suggest a brand?

Cam wise, im leaning towards Whitebrothers right now. Has anyone here used a aftermarket cam in a 300ex, if so what type.

Now my final question is who is a good 4 stroke tech?
I've heard bad things almost about every 4 stroke tech so im curious.

 

A White Brothers E-series is a good all around pipe for your quad.

 

the sparks is a good exhaust but ive heard that it takes them a while to get it to you because they make then but i would say get the white brothers exhaust,sparks cam,400ex exhaust and four stroke tech big bore kit.

 

I already have it bored and stroked to 406cc.... I need a 4 stroke tech to do the head work.
