I have fitted some Termi Race straight Thru CF cans to my S4 with a K&n filter , the bike runs much better at midrange and low down now. Thats the good news.
The problem is is now much quieter than with the stock cans, I tested them at the local racetrack with a decibel meter and at 5000rpm the termis were 86db the standard cans were 92db , and this was repeated thru the rev range from tickover to full power.
I nchecked the cans they are marked for race use only, you can put a stick down the middle all the way through so they did not accidentally sell me road pipes, oh I am not deaf, my friend 916 has trtermis and they sound awsome as does my friends M900.
How can this be , the bike runs well but sounds lousy all I can hear is clutch and mechanical noises with the termis,
also the termis are not as well made as the Silmoto cans I have on my M750 and they sound great too.
