TWO MAJOR IMPROVEMENTS WITH THE NEW STE TYPE 2  (SILENT THRUST ENDCAP) CHANGE EVERYTHING FOR 4 STROKE OWNERS SEEKING MORE POWER.

KEEP READING TO LEARN HOW WE HAVE OFFICIALLY DISRUPTED THE AFTERMARKET FOR KTM PERFORMANCE EXHAUSTS.

New Enhanced Compression Volume: Because it sticks out an inch further, it allows the exhaust much more room to compress inside the muffler before it has to get out.  This helps throttle response right off idle and makes the pull stronger and smoother all the way to red-line.  The decibel output of the new PQP cap (without the quiet insert) is 92-93 db at 5,000 rpm, which is the same as the stock xcfw cap.

Now even lower Decibel Ratings: Because there is more room for the exhaust gas to expand into, you can now use the optional quiet insert, by placing it in the end of the cap.  This lowers your decibel reading to quiet 90 db at 5,000 rpm.  The noise is lower than the stock xcfw cap, while still making more power than the stock cap.  The extra expansion room in the new cap, let’s you kill noise without killing the bottom end power and off idle response.  This is something that’s never really been done before, this effectively.
