I have read all the posts on drilling out the exhaust (the four 1/2 in. holes). But what I don't know is how deep to go. Can anybody give me an idea.

Thanks

You're going through 1/16" of steel

ya just the first plate of steel.

If the bit goes out the other end you went to far ;D

Thanks so I don't need the12 " bit then? 8)

not quite, just do not make the mistake that i made and completely remove the baffles, really loud and short lived, but did push me into getting pipes faster.

I spent $15 on the 12" long bit but really don't think the one more hole in the center made much difference than the already 8 1/2" holes in each baffle. I only went though the first plate in the center not all the way through. In comparison to sound it wasn't much louder than the 4 hole configuration that Straightjacket has if I remember right. We road together a few months ago. You might ask him he might remember. Here is a pic if you haven't seen them yet.

Want a really good sound do 8 1/2 holes in the exhaust then use a 1" hole saw with an extension and take out the center pipe.

You can also take out the hole back plate and the the actual tail pipe floating (that's the way mine is)

then remove the baffles I'm making a vid with all the different sounds.

This will be my next mod - I'll wait to hear the different sounds before I make a desision on what exactly to do.

Thanks for the advice guys. I drilled them this weekend just two in each right now and sounds a lot better. Might try a few more later.

One person on here said that you get a tinny sound, I have drilled 8 holes in each pipe and I did get the metalic sound but you only notice it if you just sit there and rev it when the rpm's drop you may notice it a little but so far I'm loveing it.

I did hear the tinny sound but, I think it adds character.

 

[snowman68]

I don't hear it while riding and I don't sit there and crank on it well not all the time so I'm ok with it. May in time go and remove baffles but happy with it right now.

I never heard the tinty sound. I went from 4 1/2" to 8 1/2" and a 1/2" in the center right away and it sounded fin to me.

It's just a 1/2 of a sec is all and only if you rev it it's not bad at all just another posted he heard it also dohen went and bought cobras right away. Maybe with center drilled out it drowns out the "tin" sound
