So, I'm changing my exhaust to a 2-into-1 and have decided on the D&D Fat Cat. However, I'm not sure which baffle will work best.

The D&D web site says that the louvered baffle is for 88 to 103 cu. in. and that the big bore baffle is for bikes from 95 to 103 cu. in.

My bike is 95 cu. in., reworked heads, Wood Performance TW6-HG cams, and 10.2:1 compression.

Any opinions regarding which baffles would be the best choice?

 

The baffles will make for differences in the power band, beginning withthe lowvered (quiet) bringing torque on earliest, then the standard and the performance baffle will give youthe greatest amount of Hp but torque will come on later in the rpm range. Also, sound level increases with each step up in the baffles.

 

i have the louvered quiet baffle,, it offers a good ballance of hp and tq and and the word quiet doesnt apply when you open the throttle ,,the 103 ft lbs comes before 3k rpms and doesnt drop below 100 until 4800

 

Called D&D today asked about FC I was told that the woods cam respond better with the perforated and Andrews cams like louvered. Might be something to look into

 

I'd like to see their test data..............
