Stock Muffler mods?

Is there any way to make the stock mufflers louder? I took them off yesterday, and want to put them back on soon, but would like it to be just a little louder. Is there any drilling or something I can do to them before i put them back on? Thanks!

ive heard cars with drilled holes, they are louder but most definatly dont sound good. Im not too sure about stock mustang mufflers drilled and how they would sound. also wouldnt that be illegal if some sort o authority finds out?

Just save your pennies for some good aftermarket mufflers.

What I really mean by drilling is through the outlet hole with a long drill bit. Maybe drilling through the chambers? Anyone done this before?

Would have to be a hell of a long drill bit.

Get a piece of pipe and a big hammer and bash the baffles in, be about the only way to do it. Of course it would sure screw up the flow.

You could cut it open, modify what you want and weld it back together.
If you don't weld or have welder it's probably more trouble then its worth though...

Ive heard tales of taking a coat hanger and pulling some of the fiberglass out to make them louder. Not sure if this is realistic or not, but what Ive read.

The stock mufflers are so quiet that if you simply try to hollow part of it out I do not see it being a whole lot louder, I would simply save some dough for some aftermarket axlebacks, I have roush axlebacks and love them.

I doubt the stock mufflers have any packing in them to pull out.

But this coat hangar deal sounds like wishful thinking to me...

No Filling but the baffles could be manipulated, if you really wanted to..

Was that a joke?

Hacking the stock mufflers is at least as old as the 60s, and probably twice that old. The method used is made harder now by the integral tips on the OEM Mustang mufflers. It was to have a skilled welder (any welder will be if you ask him) carefully snake in and cut a hole into the side of the tube that shows in the outlet end. The usual size quoted was "a quarter" as in 25 cents.

Now, even as well-worn a sicko as me has never actually seen this done. Anyone that has? Neat picture of the stock V6 muffler, NBK.
