www.supersixmotorsports.com claims a 75 HP gain from installing their ported heads, but that includes a more aggressive cam. You probably wouldn't do as well if you just installed ported heads- maybe 20-30 HP.

It won't change the deepness of your exhaust system. If you're looking for a deeper exhaust tone, trying different mufflers or getting a GT are your options. If you spend a lot of time trying to get a deep exhaust tone by using larger exhaust pipes or whatever, you'll probably wind up hurting your HP or torque. Only a GT will make both, and that's just how it is.

i thought a more aggressive cam would make a throatier tone, at least at idle. you woulod think a beefed up engine would be deeper, no matter if it wa a 6 or 8

i thaught that was true too to atleast make a significant improvement in sound. do you guys know if magnaflow mufflers sound better on v6's than flowmaster

The biggest change you can make in your exhaust tone is to remove the cats.

LT headers will deepen the tone, so will bigger pipes if you dont already have 2.5", ive heard that removing the cats will add to the raspiness on a 6, as for the magnaflow mufflers, ive got them on my car and love the sound. its noticeably different than flowmaster and doesnt sound like every other mustang on the street

if i go with 2.5" will i loose performance thanks to back pressure? what kind of magnaflow mufflers do you have? what do you mean by it doesnt sound like every other mustang on the street, are they deep sounding (more deep than flowmaster)? tell me your set up. I have true duels with no midpipe so its duel cats, how would this set up sound with magnaflows becasue i heard magnaflow systems are usually set up for single converter systems which split after the converter. My new threat debates flowmaster vs magnaflow so you can submit your reply there if you want:SNSign:

ive heard people say that you will, and some people say you wont.. i know 2.5" gives you a better tone, as for power loss, i really dont know. i know theres somebody on here who has the LT headers and offroad x-pipe, and im pretty sure its 2.5". i have stock headers, stock cats, and a custom x-pipe with 2.25" pipes going into magnaflow mufflers and 2.25" pipes out the back. the mufflers are the satin stainless with 2.25" inlet/outlet, but im not sure of the exact size of the muffler. the sound is deep at idle and low rpms, then as they go up, the sound isnt so deep as it is more race sounding instead of just being loud.

is there any other way to increase compression

To increase compression there are really only two choices neither of which you will like. You can switch out your pistons or you can change your heads to something with a smaller cc. You could shave your heads a little bit and get a little but it wouldn't be real significant. Unless someone knows of a hot head for the six I think pistons would be way I would go of course that's not really a bolt-on.

I heard the heads and upper intake and maby cam off a windstar van were a good mod for the stang (the older 3.8 in the pre 96 or whatever year they switched)

I cant remember where I read this. But I remember seeing a green fox notch in a MM&FF mag not quite a year ago with a 3.8 that would smoke most V8's (I think it was the six offender) and they said the plastic split port induction intake was one of the best flowing intakes for the 3.8

That was Super Six Motorsports 4.3L Stroker using the windstar plastic intake (which is also the same as the F150's intake, but the F150 is metal and stronger), plus they threw a shot of nitrous in it to run 10's.

The sound will change some with a cam. A deep sound is caused by the frequency of the wave. An I4 has a high pitch because it has 4 cylinders firing out of the same header causing a short frequency, V8s have 4 cylinders in one header, but those 4 don't fire off back to back thus increasing the length between the peaks of each pressure wave. A cam can imitate this by changing the timing of the exhaust valve thus spacing out the peaks alittle more, decreasing the frequency and creating a lower pitch. But a V6 sounds like it does because the 3 cylinders fire off closer and more often than the 4 of a V8.
