Mine seemed to wind down quicker than with the stock. Possibly a function of lower back-pressure. Anyway, no problems over a 1000 miles since I put the Arrow on. Emission control is closed loop over a large part of it range. Let it do it's trick and adjust.Got the full Arrow exhaust installed today, sorry too late for pics. I will post some tomorrow.
The exhaust (with the silencer installed) is as I have heard only about 10dBA louder than stock, but with a much deeper grunt to it. It sounds so much better, but not too loud. I can hear it a little more in city driving, I don't think it will be much different on the highway, I will find out it a few days.
However, now it really is trying to shut off while blipping the throttle, more so than with the stock exhaust. Anybody know why?
Im thinking that a Bazzaz will solve this problem and give me more power.
That's a respectable garage!!!I have Arrow on all my bikes. Some of the best on the market today.

Thank you! My R1 has become my race bike since that picture and has won a few timesThat's a respectable garage!!!
No its not. If something creates noise at 70dBA, 80dBA is not twice as loud.10 dba increase is considered to sound twice as loud....generally.
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.No its not.

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.Not to be pedantic, but sound is a very complex subject.

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.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..
