If none of the owners will fess up i will tell you what they said. THey like the tuneability and they have beaten big gun's, white bros., etc.
sounds like a great pipe.. its what i'm getting on my 400EX when i get it.

 

I would wait and see if DMC comes out with a pipe for it.They make the best pipe for the 400EX period. This is no B.S.

 

The DMC is not the best pipe out there for the 400! There are ALOT of companies that make pipes for the 400 and not all of them have been tested and proven to be a good pipe!!

 

Actually the DMC is the best pipe for the 400EX and GT THUNDER has dynos to prove this. There is no other pipe on the market that flows as well as the DMC. Also, it is the best pipe for a built 400EX as well.

I have owned a FMF pipe and the big gun system, I personally thought my bike was faster with the FMF then the big gun. With my mods my big gun is holding my power back big time,and I need an awesome pipe, so I called everywhere, I asked people, and everyone I have talked to said get the DMC, I have researched for about 6 months on pipes for the 400EX and clearly the DMC is the best, PERIOD.

 

I am wondering when the DMC became the best 400EX pipe. It is my understanding that the non mass produced pipes like the SParks X-4 and X-6 and also GT THunders newest race pipe seems pretty good that was there best dyno on a race 400EX.

I have had the Sparks X-4 for along time and the quality and power are excellent. I am now getting a full Sparks 440 National with x-6 exhaust. Also, Sparks has a full system now available for the Raptor and knowing how serious SParks is I am sure it is an excellent pipe.

What ever happened to White Bro's R-Series silencer? Was that any good?

 

If you have looked at the GT THUNGER dynos,the DMC pipe puts out the most horsepower of any pipe they tested, even there own personal race pipe.GT THUNDER tried to put the Sparks pipe in the shootout, but sparks didn't want to be involved in it. Maybe they weren't to sure of the performance of the pipe. Even the graydon proline pipe is behind on the DMC and that is one of your non mass produced race pipes, the DMC produces 3% horsepower than the Graydon.

WELL SAID, LDJ.I HAVE THE DMC PIPE AND TO TELL YOU THE TRUTH, I DON'T THINK THERE IS A FASTER PIPE OUT THERE.
