This of course is my personal observations and opinions, First of all this combination is just wrong IMO paired with the Long tubes. I now understand why they pair the Hpipe with these mufflers. The tips stick out quite alot furthur than the FRPP 5GT exhaust. At idle the exhaust is extremely quiet. At normal cruising the mufflers are also very quiet. The mufflers have no drone what so ever.which is good. As you get into the throttle the exhaust is extremely high pitched (dont like it) and fairly loud. At WOT it is very high pitched and somewhat loud.. Not good! Downshifting the exhaust is popping (kinda like Magnapacks) not good! I have a few options or choices. 1. Take the headers off to quiet the high pitched sound. 2. Install an Hpipe which I will have to get made since there is not one available for Kooks Lts. 3. PUt the FR 5GT exhaust back on which has an excellent rumble. 4. Finally I can live with it and hope to get used to it. The exhaust has maybe 5 miles on it so there may be some change after a few miles/ Again I am not forcing my opinions on anyone else. I am sharing to maybe help others that are considering this exhaust. If you dont agree with me I respect your opinion. Please share your thoughts if you too have installed the M-5230KR axleback
