400ex exhaust. Curtis Sparks vs Duncan fatboy 4

[bigH]

i currently am running a duncan fatboy 4 exhaust on my ex. i was told id get alot more power out of a curtis sparks exhaust . i have the money to do the switch. is this exhaust really better then a duncan. is there power a difference considering they say sparks is the best ex exhaust?

Well your Fatboy 4 isnt crap either. If you had the stock exhaust or a very cheap exhaust I'd say go for it and never look back. But you already have a quite good exhaust so in my opinion it's not worth moving to the Curtis Sparks.

Offcourse Curtis is the exhaust pipe for a 400EX. :)

Im with the others. At most you may see a 1/2 hp or so with a switch. For the $500 that an CS cost you can do alot.
