I there any tip that makes the exhaust quieter, if so which one?

 

There are ends that have deflectors of different shapes. They are marketed as heat sheilds but may squelch the sound some too. There is also a turn down end cap for the e-series which might reduce it a little also. Otherwise, the best bet is to remove some disks. I have ran 5 & 8 in mine, and the only thing I noticed was less noise with 5, no power loss at all. This was according to my precise A$$ dyno.[img]i/expressions/face-icon-small-cool.gif[/img]

 

WB makes a quiet core for it, lessens noise by 6-7 dbs. They are around $30-40 if I remember right. Rockymountain and Dennis Kirk have them.

 

get the q-core and drop down to 4 disks and it aint to bad i am running 5 and the q-core and its not to bad
