im looking into a new pipe amd or full system. sound is an issue, but id like it to be adjustable for when i ride places that dont require a sound limit thanks

 

Suposedly White Brothers E seris is the best, according to the lasy dyno shootout I read.

 

BUMP

 

I agree, go wit the WB E-Series thats what i'm gettin for my 300

 

hey mbrp, what kind of price on the tech 4? what kind of hp numbers and where in the powerband is the increase most significant?

 

The WB is a great pipe, but a bit on the loud side. I have the big gun with the quiet core installed and it is quieter than the E Series but still gives a good boost. Looks great too.

 

I have an FMF Powerbomb header with a White Brothers E-Series silencer. Two of my riding buddies have 400EX's and both of them run the WB's Pro-Meg. My bike has ton's more low and mid power, and they take me by a bike length on the top end with the Pro-Meg setup. I mainly use my bike for trails, mud, etc. so the low and mid power is what I need. Hope this helps.

 

CT racing slip on, jet kit, rev box, filters. Loud but fast. U won't like the e - series when your tire hits it and breaks the mounting bracket on your first big air.

 

oops, one more thing !!!! get the e-series if you like looking at elbows and butt cracks.

 

Go with the Sparks pipe either the x-4 or x-6. They won the ATV Sport shootout for best pipe. I really like mine it is a nice deep throaty growl..even sounds deeper with the new fcr carb.
