Pro Circuit Ti-4 Titanium Silencer + Head Pipe

Pro Circuit Ti-4 Titanium Exhaust for KFX450R
Pro Circuit pipe for KFX450R

Pro Circuit Ti-4 Full Pipe installed on our Kawasaki KFX450R


The Pro Circuit Ti-4 is constructed of lightweight brushed aluminum and stainless steel, itís tough and it provides solid horsepower increases and strong acceleration. The T-4 can be performance tuned with a selection of end caps and it works with either the factory head pipe or a Pro Circuit head pipe.

The full pipe installation was a breeze. Removing the old pipe took about five minutes, and installing the new pipe took about 10 minutes.

I then downloaded the new map to the Power Commander III and it was good to go.


The exhaust combined with the Dynojet Power Commander III made a noticeable power difference and opened up the motor from bottom to top. Off-idle hit is strong and immediate and doesn't take away from the rider-friendly feel.

Noise output is nice - a throatier tone without adding much extra noise output.

The fit and finish of the pipe is great.  Everything bolted right up and we even reused the stock leg protector.
