LD85

OK, The loudness of my SS Magnaflows was becoming just too much and I did not enjoy driving the car,,, so,,,,

Saturday, I pulled out a bag of Steel Wool and cut the length of the package in half.

I then shoved 1/2 of the length into the muffler tube closest to the center of the car. I can still reach it to pull it out if I want, in case I go to the track etc. I packed it in tight with a long 1" diameter wooden dowel so it wont blow out under WOT.

Anyway, it sounds perfect to me now, the car still noticeably has a 406 CI performance sound and my head doesnt hurt after long rides of listening to the stereo over top of the exhaust.

It is not what I really wanted to do,, but I am glad I did it, and it is reversible!

in currently wanting to hush my vet a little as well, did your set up kill a lot of power? did you notice a big difference?

this has me very interested as well. my little 355 is still head-banging loud, i too have to crank up 200 watts 3/4 of the way and i still get to hear the exhaust! i mean, i like it, but not 100% of the time.

This is very interesting. I have been complaining alot lately about my first generation B&B. I may have to try this. Steel wool is flameable, right??? I would like to know what is available to muffle the muffler?

I am sure that there was some sacrifice of HP, but hey I figure I have @ 485 Crank HP, if I lose 10 HP and pick up some hearing, then I figure its a wash!

OK, here is a pic to clear up my whacked out description

This sounds very similar to how they make a silencer for a gun (or so I remember seeing on some show on the History Channel!!!). I've been hunting the forums for hours looking for various solutions for quieting the exhaust a tad. I think I like this non-permanent solution the best so far.

anyone know where to buy bags of plain stainless steel wool (ie, not the steel wool pads). i looked in autozone, advance auto parts, home depot, lowe's, the dollar store, k-mart......to no avail!!!

I've always found it in basic hardware stores. As far as I know it is still used in sanding trim by some people. Another idea, although I have no idea if it will be here, is Super Walmart, around where they keep the cleaning supplies, or over in the paint section, or where they keep the sandpaper if thats not in the paint section. Seems like I remember seeing it in walmart.

You can use anything...toilet paper, if you wish. All you are looking to do is plug the passage.
If it were me, I'd make an aluminum plug that just slips into the exit and is held in place by one or two machine screws. Be easy to put in and take out, and would last forever.

the easiest way is to cover one exhaust pipe with a plumbers jim cap.....it's rubber, uses a screwed clamp and is easy to remove when you want to make noise......but everyone asks what the heck is that.

I have considered taking a piece of aluminum that is round & close to the ID of the muffler tube,

and inserting a disc that has a tapered set set screw in it so you could expand the disc inside the ID of the hole.

I wold have to cut a slit into the disc so the tapered set screw would allow the disc to expand and wedge itself into the hole.

I also considered cutting a piece of expanded metal and trying to attach it to the opening,

but really, this Steel Wool is working so well, I just have not taken the time to do any more with this, but I will in a few weeks.

Red Tornado

Larry, what would you be doing in a few weeks, regarding this?

LD85

Brad, I just have to measure the ID of the tube with a set of telescoping ID mich's, to figure out if the ID of the tube is a standard size or if I have to turn down a disc or slug of metal in a lathe to fit the ID.

I want to do something simple so it would be reproduce-able and easily removed.

The problem mainly with the Magnaflows, is that the muffler tips are rolled over making the ID of the Muffler tips small at the opening and larger behind the opening.


So I figure that fitting a piece into the muffler exit tube will be the easiest solution. If I can figure this out, I will make a couple of sets so maybe you could try a set too for a second opinion.

I changed gears to a higher number and the resonance/noise changed as the rpms were higher.
Try drving in a lower gear and see if the noise is lower, not that droning noise when you lug around.

Larry, thanks for the explanation & the offer -- I'll take you up on it! Just PM me whenever you're ready & let me know

LD85

Hey Brad, I just looked at it again quickly in the garage and it looks like there is a short "turn down" for @ 1" long in the muffler tip, before the tip joins to the muffler body.

So effectively, we can put plug or obstruction in this area without having to put it inside the perforated muffler tube. THis is good because it is a larger ID than the muffler tube

I will check into this some this weekend! Stay tuned!

Red Tornado

Larry, sounds great, let me know and I'll paypal you!
