Had a nice highway ride with the new exhaust. I cant hear an increase in noise level from the exhaust on the highway, only below 60mph can I hear the increase in noise.
Great exhaust, sounds good, looks good, and gives a little bit more power.
Plan on posting a pic tomorrow, after I clean the tree sap off the bike.

thanks for feedback,, how does it sound to you at a ride-by?
also, is a 'db killer' fitted,, if so, what difference..
for me considered verbal descriptions are as important
as are videos on utube, which are helpful guides but
can also be misleading as to true tones/noise etc..
No its not. If something creates noise at 70dBA, 80dBA is not twice as loud.
Not to be pedantic, but sound is a very complex subject. The psychoacoustic measurement of +10 db is considered twice as loud. Just a generally accepted rule of thumb. This does not take into account distance, duration, frequency or other variables. Whether A, B or C it is a logarithmic scale.

Im glad that you understand sound levels so well, but when you say its twice as loud you may be confusing people who don't understand noise levels. I understand what your saying because I take noise level readings to keep compliance with OSHA regulations, but in general, 10dBA is not twice as loud. In most cases an increase of 10 dBA is barely noticeable, especially when most aftermarket exhaust increases the noise level well above a 10dBA increase.

Im not sure about a drive by, but my friends have commented that they could tell a difference and all have said that it sounds better but barely louder.
