Okay I've narrowed it down to these three. I originally wanted to get a DMC. But I want to know if it'll really be worth the $500. And I really like look of the Sparks X4. The WB e-series won the Dirtwheels shootout. What do you think I'd benefit most from? If I get E-Series it would be the slip-on only. The other 2 would be the full system. I have a K&N and a 155 main from when I had my FMF. I want to feel a real difference in power.
Thanks for the replies.

 

I used to to have a megamax2 and my dmc made a huge differnce over that.I havent rode a 400 with the other pipes you mentioned but my friend has a yosh slip on and his runs pretty good too.

 

Hey, if you can afford the cash, get the DMC. It is a great flowing system. If you are planning on getting any mods done in the future, then get the DMC, it will handle your mods to come.....

 

I have a DMC on mine and i like it. It really does respond well to motor mods. I'd recommend it over the other pipes.

 

You might want to think about the LRD. For 365 dollars it might be the best pipe out there for the price. I love mine.

 

Check out the March issue of Dirt Wheels. The did an exhaust shootout for the 400EX. The overall winners was the White Brothers series E pipe. It was tied for the most horsepower but is was significantly quieter than the other pipe. Not sure if the pipe you are interested in in the the shootout. There were about 10 pipes in the shootout.

 

I've heard the Sparks pipe is pretty good and I believe he wants 400.00 for it. I only had 2 pipes to choose from and that was the Sparks and the LRD. I went with the LRD and I like it ALOT!!!!

 

I know it's expensive, but I highly recommend the Yoshimura RS-3 Full Race pipe, and buy a sparky for it. It will rock your world.. and your windows Later

 

I have the sparks x-6(spark arrested) anyway the sparks and ct pipe are the same. by looking at my pipe and seeing the ct pipe on their site, I came to realize that they are the same. except for the fact that the ct pipe is $100 less than sparks.
if money not an object, get the pro yoshi full exhaust. at under 5lbs, it's lighter than my muffler alone. think about this, for about $600-$700. you get a full exhaust and a ten to fifteen pound weight loss.
if money is a problem, dg makes decent full systems under $400.
big gun sucks monkey poo.
pro circuit looks real sharp and very promising.
just remember that you will get larger gains with better air flow, more compression etc.
think long term, not what ever I can afford at the moment.

Does the dmc come with a spark arestor? or do you have to buy it seperate, and does it rob any gains achieved.
