I totally agree. I got my full 300r system for $60 shipped and it made a nice noticeable difference. Had to rejet from a Keihin 122 MJ to a 128 to account for the difference in flow. Unfortunately it's only 2 pounds lighter than stock. Louder than stock but not nearly as obnoxious as most aftermarket systems.

 

My full Muzzy was $389.00

 

The guy who started this thread hasn't been on here in a year.

 

Why you gotta come in here and ruin the thread resurrection party ?

 

That's how I roll...

 

Man... I was going to tell him to just take the exhaust off and run it that way... I'm too late, I guess.

 

My local dealer (Australia) ordered a powercore 4 pipe and power bomb header from the States Its being fitted with a 300cc kit and dyna jet kit at same time along with de-restriction of the carbie slide and as a few of you have already done these mods, I am curious to how noisy they are and difference in performance these modifications make.

 

Had an HMF, bad fit and too loud for me, even with quiet core. Went to the FMF Q4 great fit and sound quality/ level.
