macmac, you are wrong.

With all due respect. :)

I am a uncertified xpurt on the debaffle of stock mufflers. I have done xtensive testing and trust me, wasted a hell of a lot of money. I was also one of the biggest people, (275) pounds, of why it was a waste. But now I think I differ on it. Let me first address the loss of torque issue.

If you look at the pipe size from the heads coming down, going into the goat bladder and the pipe size of the end of the muffler itself that goes into the goat bladder, it is the same diameter of the silencer, baffle, whatever it is called. So you have a reducer going in and coming out as far as pipe size as the baffle. The baffle offers you no reducement in size of pipe so you are basically getting the same back pressure.

The difference is it isnt backed up into an exspansion chamber before exiting like the baffle has. This is what also causes the poor throttle response and to me the lack of smooth acceleration.

Now as far as leaner. If it is dripping in blood, how damn lean can it get. :) I really dont think the air/fuel ratio changes at all. You are not pumping in any more air, or out. It is just a smoother bowel movement. I agree the marble is needed as it accomplishes or tries to what you recomend with the reed valve removal. I may pollute but my lawn tractor is a lot worse at it.

So, after doing this test back and forth and back and forth and back and forth for a year, I say it is ok. The powerband does change from the low to the high side, but isnt that what is needed so you dont lug the engine. I rev my gears out a lot further but dont get that teeth vibrating chatter that I did with stock pipes. So Mr. Maple Man, what do you think? Can I be right, or do I just need commiting to a good VA Hospital, if there was one.

Also when Trip gets back, I have a question I want answered. Dont worry, I support paypal here. Trip I know is debaffled and has been for a long time with no issues, but yet he is selling a set of stock pipes. What gives Trip?

BlownDodge, I am in your corner and say anyone who doesnt debaffle should, well, vote in the Iranian election.
