How can I make my exhaust quieter.

Hey guys. Right now im running a single cat into one "flow tech" muffler that dumps before the axle. It's incredibly loud! Sounds great and I love it. Only problem is the new place I'm moving too has a bunch of old people and I leave early and come home late and my bronco is too damn loud. It's a senior citizen mobile home park. So I kind of need to respect everyone. Also driving on the freeway sucks cuz it's so loud. Is there anything cheap I can do to quiet it down a bit? I still want to hear it and I still want it to sound nice but I've heard nicer exhausts that are only loud when you're in the skinny pedal. Should I throw a resenator on there, or will simply adding a tail pipe quiet things down? Any input is appreciated.

Put a stock Y-pipe with either stock cats or a single modern hi-flow replacement, a stock-style muffler, & a stock-style tailpipe.

I have stock y-pipe and 1 cat. I do not want to go stock because I still want to hear it. The stock exhaust I had on my old bronco was way to quiet. This is just way too loud. There has got to be a happy medium.

Not for me - it's a happy MINIMUM. Quiet is better in every way.

Noise doesn't make you go faster; doesn't make you go farther; doesn't make it cost less; doesn't make it more comfortable; doesn't make it more reliable; doesn't make it last longer; doesn't make it easier to maintain; and doesn't make your weenie bigger.

That's what I was thinking actually. But I'm not sure that would be cost effective. I honestly think adding a tail pipe would quiet it up a lot. Does anyone have experience with this?

Well that's boring. I like to hear my engine. It's an amazing sound and does some amazing things to the neurons in my brain :)

Take a look at GIBSON cat back exhaust systems. Great quality. Reasonable. Quiet but not too quiet. I have one on my 95' 5.8. sounds great. Has been on for 6 years and no signs of rust.

Why not use a flowmaster 40 muffler. It should quiet it down. Just don't mash it down.

I try to go slow at night but it's so loud, plus when I pull up next to my house it resonates like crazy and I know my neighbor wakes up! Lol

Tailpipe should cut it down a bit. I ran into the same issue on my '78. I was running a flowmaster super 40 with just a turn down. I added enough tailpipe to go over the axle and then it just points at the ground. It probably cut the noise by a 3rd. Also it sounds better this way.
Another option might be a tailpipe then run a supertrap and then it would be tunable and you could open it back up easy too. Just keep adding disc's until its as loud as you want. Or take them away to make it quiter

I found the flow master 50 gave me the little rumble going down the road with out driving me crazy or anyone around me, and it screamed pretty good when you were on the gas. I don't like loud exhaust either, I like just a hint of something under the hood... but than of course you have to have your engine built to...

yo TONY,
For exact replacement exh parts, I use Walker, who was and prob still is Ford's OE supplier (esp for our Broncos)

Use pn's and gOOgle for sources & prices; then try locally and have them beat or match prices.
Use aluminized or SS

See my partially recovered Bronco web site. Thanks to Mr. Schwim!

I run shorties, a flomaster 80 series (Bigblock), 18"X8" Magnaflow glasspack and it terminates behind the axle. Nice little rumble but not loud.

Get the mandrell bent tailpipe and add an inexpensive 18" glasspack, (not the big magnaflow I got).

My muffler has 2 outlets do I'd either have to get a 2-1 adaptor or have a muffler shop make a custom tail pipe. I think I'll try just a tail pipe first, that should be cheap, and if it's not quiet enough yet I'll throw in a glass pack. Should I throw the glass before or after the muffler?
