Hi - this ties in with my exhaust questions, but it's a different topic .

What's a good muffler to put under our cars for a nice subtle sound at idle, but screams under WOT? I don't want something that obnoxiously says "Look at ME!!!".

My brother has Mac's on his 5.0L Mustang, and it's too rumbly for my tastes. On the other hand, my Marquis has flowmasters on it, and although I like the sound, Flowmasters supposedly create alot of back pressure to get that sound, and I don't want to hurt performance with my mufflers on my Cougar.

Any suggestions? What worked for you guys?

 

[Kevin]

Nobody's put mufflers on their 5.0's ?

Or is nobody happy with what they've got ?

C'mon people - I need suggestions!!!

I like my flowmasters just fine. Before I got them I had no mufflers. The flowmasters sound quite a bit better to me. I would like to try out the Warlocks. Those are the one that have the straight-thru bypass for the track.

I was going to replace my mufflers a few months back, but after chopping them off I couldnt resist starting it up, just to see. And it wasnt nearly as loud as I thought it would have been (I'm thinking the cats and resonator MIGHT be doing some work too ) So I drove it around as such, the interior resonation was really loud, I almost put the mufflers on, but I decided to try putting straight pipes on so the exhaust would dump out the back, rather than under the trunk. And that almost entierly eliminated the enterior noise. So I left the mufflers off, its a bit throatier than you might want, but it was cheap as hell to do. And it does sound pretty sweet at WOT, especially in tunnels

I have a 91 Cougar with the 5.0, it just had the mufflers and resonator cut out and pipe installed in its place. It load, but not too load. I have gotten several comments on it. If you dont want it too load, just try the gutting the mufflers first, and if you dont thinks its mean enough, cut the resonator out.

As for loosing horsepower, I have had it at the track with and without mufflers, and it ran faster both times without, not too much, but enough to see the difference.

 

[JJanney]

I've actually been thinking off chopping off the mufflers. The stock ones have three chambers that really kill sound and bottle up air. I might do what ratbastard did, chop and put straight pipe. That'd be good enough for right now.

 

[Kevin]

LOL - I did the muffler 'delete' on my Marquis (duals with cats), and got sick of it after a year - hence the flowmasters on it.

But I don't want to do that on my Cougar, as there will be NO catalytics, Just a 2 piece new system from the headers to the bumper, with an EXACT match for the factory Y pipe to back in come emissions testing time.

I agree that a straight pipe in place of mufflers would sound really good if the resonator were still in place (kills the popping sounds on decelleration from WOT), and with the cats. And - "Cheap as hell" .

Hmmm - I don't know why it only just occured to me, but alot of the guys on the CrownVic site have put mufflers on their 5.0 Box bodies. I'll ask there too .

I love the way dynomax turbos sound on a stang and the way my dynomax bullits sound on my bird, i got tored of the way a flowmaster sounded, it idled great and souned good till 3k rpm then it was real crappy

I have Dynomax Super Turbos and it sounds pretty quiet when you are at idle then when you get on it i would say it is a moderatly loud sound but not too loud. It also makes the car a little bit louder if you remove the air silencer.

 

[Kevin]

Hi Gary - yep, the air silencer was removed EONS ago !

It has stock mufflers, and original stock exhaust system on it right now (my custom front Y pipe came off for emission testing), and it STILL turns heads when I WOT. It's MUCH louder than my Marquis.

I also heard Dynomax's last night, on a Mustang with high flow cats (which I will buy eventually), and although the sound was very crisp and sweet - it was QUIET!!!! Screw that - I want a louder car than that at WOT.

I'm thinking of going with the Mac's afterall. The price is right, and I do like the sound, and the only drawback is a bit too much volume. And when the cops are chasing me, they'll know where to look if they open their windows and listen for my exhaust !

Now, to track down the guy who's going to build my exhaust.......

Thanks guys - Kevin.

I am going to go with twin supertrapps, you can run wide-open, or tune them.
Everyone at my local road course uses the, but they are'nt cheap, around 130-150 a peice.

 

[392Bird]

I used a Supertrapp on my cycle, and it is nice for sound, power, and adjustablity. <br>

hey 392Bird...ya got a website or anything showing your build up of the 392? I'd love to see it!

mufflers

i use flowmaster 40's on ,y 93 5.0 tbird and they sound really nice, plus i removed the resenator. i also heard that magnaflow makes nice mufflers i have then on a mustang 5.0 and they sound really good too.

 

[91HellCat]

I put the FLowmaster kit on my 93 LX. It is the catback that replaces the split in the back with a Y and 3 chamber mufflers. I have yet to hear it sound bad all the way to 5000 RPM. All my friends like the sound. Kinda mellow, but you can tell it has a HO 5.0

 

[BosNA302]

On my 91 I just finshed welding up 2 1/4 inch downpipes off my headers, into a Y I made, and then through a single Hooker maxflow straight through, it then snakes out via a flowmaster cat-back exhaust pipe, but where the rear Y used to be, I just cut it (and the mufflers) off and added a piece of straight pipe. It exits facing straight back right under the spare tire well. Sounds great, and flows free, the hooker maxflow 3" flows 95% of a straight piece of 2.5" pipe of the same length, but controls the noise.. and still sounds badass when I get on it.

Like I said above, I cut the stock mufflers the other night with the help of Mark 5.0. The exhaust sounds a lot better and I'm bought just regular tips and some pipe to extend from the cuts I made. No mufflers until I can get a real true dual system.
