Please, anyone that can help, do so. I would like your unbias opinions on which exhaust is the best for the 400 EX.

 

Wher do you ride, do you plan on keeping the engine stock, if not what mods?Carb ,piston cam etc. There is no one perfect pipe. I had a Big Gun.They are great pipes but my DMC performs better with all the stuff that I have done.

99 426ex , Web Cam, FCR carb w/ twist, CT revlimiter, DMC exhaust, XCT's ,K&N, One kit, Renthal bars, DG nerfs, Armidillo Swingarm plate, 8 paddle Haulers

I also heard the DMC is the best, but the whole system is very expensive. I run a Pro Circuit headpipe and silencer on my 400ex.

 

How loud are the DMC and the Pro Circuit? A lot louder than a Mega Max II with all the discs on it?

 

DMC is a full race pipe, it it lets everyone know they better go faster or get out of your way. Pro Circuit is loud also. The Big Gun with race core is loud. E-Series is in the medium category along with the Big Gun super quiet core.

 

400ex'r,
How does the sound of the Big Gun with the Super Quiet Core insert, and the White Brothers E-Series compare to the stock exhaust? Does anyone know the decibel levels on these 2 systems? How about power? Which gives the most horsepower and torque?

 

I am also looking for an upgrade full exaust system, what is the advantage to a tunable disc muffler? I would much rather have a non tunable system, I like how the pro circuit muffler looks, But I want the most powerful system made, so what is it?

 

Go with the DMC It is able to run with or without a tunable disk system. The disk system is the spark arrester. This is a better pipe for a modded engine.

How does the White Brothers E-Series system compare to others? Is it the best? The second best or what? I really like the looks of the E-Series, and I've heard you can get tremendous power gains. What about other systems such as the Big Gun and the FMF Power Core IV-2? How do they compare? Are they up there with the E-Series? Or below it by a lot?
I live in an area where sound is sort of an issue. I don't want the loudest system available, but one 100 decibels or less is alright I guess. How loud is the White Brothers E-Series with the quiet core installed? Do you lose that much power with it?

PLEASE HELP!

 

Air, who is DMC? Phone #? Soon I would like to do the cam and other mods but like doing them one at a time to see the results. After all, I have only had the quad for a week!! Will I see a huge improvement by just full exaust, jetting, and the white bros. rev limiter? Also, I bought some 8 paddle haulers for the sand, how do you like them?
