Epcos too loud? Try this... #353845 09/15/2009 3:50 PM

The washers were the same outside diameter as the baffles so they fit perfectly. The result is a deep throaty rumble that is not too loud or raspy. The added back pressure also takes care of any popping on decel. I don't know how to post pictures but if someone wants to see pics of this mod let me know and I will e-mail them to you. -- bikergeo

I have used many washers for back plates in baffles and have had great success changing the performance as well as the sound. Varying the size of the opening makes a big difference. Modifying stock pipes A word to the wise is not necessary. It is the stupid ones who need the advice. Pat

Just 2 days ago I cut two washers that are 2 1/2"s in diameter and installed them in the end of the stock slash cut mufflers. I took out 3 baffles each side and had an exhaust note I really liked. Not one to leave well enough alone, I punched two 1/2" holes in each remaining 4th baffle. Then I had a sound that was too loud and raspy for my liking. Now, I seem to have reduced the volume by about 30%, but have an exhaust note that sounds like a 4 cylinder. Not sure if I like this mod. "You're a long time underground!"
