How To Tame your Slashcuts
By Ken #466
If you're
like me and think that the stock exhaust are too quiet even after drilling
out the baffle end caps, yet you think that the slash cuts are way too
loud, you may want to try what I just did.
The next
logical step for me was to quiet down the slashcuts. The theory is simple.
Make the hole that the exhaust passes through smaller.
Here's how
I did it:
1.Using a
hammer, 1-1/8" socket and a 6" long socket drive extension, press 1-3/4"
automotive freeze plugs into the inlet end of the slash cuts.
2.Drill a
pilot hole in the center of the freeze plugs with a small diameter drill
bit.
3.Expand
the hole with a 7/8" metal cutting hole saw with an
extension.
4.File the
burrs off of the drilled hole with a rat-tail (small round)
file.
That's all
there is to it. Now my modified slashcuts have a sound somewhere in
between the modified stockers and the stock slashers. A little more
throaty, a lot less harsh. I haven't heard of anyone trying this before,
so you can all send your royalty payments directly to me ;~) I will be
posting pictures of the procedure.
Note:
I made one
boo-boo while doing this, but in the end it caused no harm. You'll notice
in the pictures that as I hammered the first freeze plug in, the welds
broke that hold the inner sleeve in the muffler inlet. I pushed the sleeve
in about 1/2" before I realized it. To even things out, I purposely did
the same thing to the second muffler. You should try to avoid this, but if
you don't, it really shouldn't matter. My mufflers clamped on to the
exhaust pipe just as tight as before with no noticeable blow-by at the
connection.
