Hey everybody, Hope everybody had a good/safe weekend. I am looking for opinions on the muzzy M14 full exhaust and power comander or two brothers v.a.l.e. 4-2-1 full system and juice box. Specifically does either one take away bottom and mid range dramatically and is one louder than the other. thanks

I was sold on Brock until the PC5 came out... no bung at the time on Gen3 exhaust. Started looking around at everything. Ended up back at Muzzy, which is interesting, since every Kawk I've had since my Z1 eventually got a Muzzy on it.

The new M14 Muzzy is tuned for the 08-09 ZX14s, or 06-07 with the flies out and ignition advanced 4 degrees (I think). It has a bung. And Muzzy has always made excellant power on Kawasakis.

The new Brock exhaust has two bungs, but I'm not sure why yet.

So whatever floats your boat. I'm going with M14 Muzzy this time.

I'm still sold on the Muzzy M14 but the new Brocks CT-Dual titanium makes gobs of horsepower (more than any other full system Brocks sells, I believe, based on their own dyno tests) and sounds great and weighs nothing, and finally has O2 bungs.

Hard choice! What I want is low-moderate sound, and optimal low- and mid-range horsepower and torgue improvements. I don't run flying miles for speed, or drag race. I ride on the streets, and in the mountain switchbacks. Either of these gives me that, proven on dynos and real world... guess I'll have to flip a coin.

Muzzy M-10. I've had it on my 2006 for 2 years. Its a shorter pipe than the M-14. Looks great and sounds great
