I am thinking about either buying a dg rcm pipe or cobra jet systems exhaust for my 300ex. What do u guys think i should get?

 

There are so many good pipes out there, these are among the worst. Cobra is just a noisemaker, and the veteran riders tell me that DG stands for "don't get". Read thru Dirt Wheels or other mags, there are better ones available. Instead of going the cheapest, save your money till you can get something better

 

I have an aluminum cobra on my EX. Combined with the other mods I have you can tell a difference. The cobra and dg both are very loud, however I believe it would be almost impossible to purchase a more free flowing pipe than a cobra because they run almost straight through.

 

Yes, they are very LOUD and there not up to par with there competitors.

 

I don't know about cobra, but dont get DG's pipe.
I just bought a 300ex with a DG pipe on it and the quad seemed to take a few cranks of the motor to get it started, and it didnt want to idle when cold.
Yesterday i installed my new Supertrapp IDS2 exhaust on it and now the 300ex starts right up and the idle seems alot better.
Besides that the DG pipe make my quad sound like a harley. Nothing more than a noise maker...LOL

I HAVE OWNED BOTH AND RIGHT NOW I HAVE THE DG ON MY 300EX. I PREFERABLY LIKE THE COBRA BETTER BECAUSE IT GAVE ME JUST A LITTLE BIT MORE HORSEPOWER BUT IT WAS LOUD AS CRAP! IF YOU WANT A QUIET PIPE DONT EVEN THINK ABOUT GETTIN THESE CUZ THE DG IS JUST BARELY QUIETER BUT DEEPER SOUNDING.
I HAVE HAD THE COPS CALLED ON ME 7 TIMES WITH THE COBRA AND 5 WITH THE DG SO TRY TO STAY AWAY FROM NEIGHBORHOODS.

 

THE COBRA MAKES A CHEAP LOUD ANOYING NOISE AND YOU LOSE POWER!! DONT KNOW ABOUT DG, NEVER HEARD ONE OR RODE BIKE WITH ONE, BUT I HERE ALL BAD. TRY WB,DMC, OR YOSHIMURA
