I was talking to Brody at FMF Racing and they have a replacement spark arrestor end cap for the PowerCore 4-2 swweeeetttt.. I recently blew the spark arrestor screen right out the back of mine and they are sending me the new endcap for free... Sweeett .... GUESS WHAT THE POWERBOMB HEADER IS SHIPPING TODAY WHOOHOOO

 

Skunky, have you had a chance to compare noise level and performance between your EX and other 400EXs with the E-Series or IDS2? I'd REALLY like the DMC dual, but I don't wanna spend $450 for the complete system, so I'm gonna stick with a slip-on. What I'm looking for is the quietest slip-on I can get that still provides a decent power increase. Thx for the help.

 

Man the powercore 4-2 is not going until next friday... darn...... As for side by side's yes i have with the e-series. The 4-2 is louder I fell it is one of the loudest pipes out there. My 4-2 ate up the e-series but i had more mods anyways.... Look around this topic has been discused a thousand times.
