Louder- LOUDER!!

[Master_Chief]

Hi, I was wondering, what can I do to my '99 GT to make it louder
I already have a full flowmaster, but is there anything else, other then exhaust to make it louder?
Thanks

Take off the air silencer if you haven't already. And swap to a midpipe with no catalytic converters if you haven't already. A catback won't give you much more volume.. but a midpipe swap sure will.

whoa, sorry but I am (sadley ) not too schooled in the "lingo" yet- would you mind telling me where the air scilencer is?

its in your engine bay, its the little rubber thing that feeds cool air from your fender well to your air filter.

Get a K&N or other brand open air filter intake. Then swap out the mid pipe with an off road H pipe. This removes the 4 catalytic converters and really makes the Flows come to life. I am running the no cat H with Flowmaster Super 40's and it sounds awesome. Then do a search for the IAC mod or copper cap mod. This will help drop the RPM's faster when you let of the gas. Gives it the deep burble when shifting or coasting. Do all this and your probably as close as your gonna get to an old muscle car without going to long tube headers and cams.
Plus you'll usually shut up the Ricers with the coffee can exhaust tips cruising the mall parking lots.

o/r prochamber sounds good with flows

but it's all opinion tho

O/R mid pipe!

SLP

Or go with a SLP loudmouth set-up, those bitches are loud!

An opinion that I totally agree with though! Off-road Prochamber midpipe with flowmasters sounds awesome!

is this same thing possible on the 99+ stangs and give you the same results? or is this a strictly sn95 mod?

Install a midpipe that has no cats or high-flow cats and you will get a more robust sound.

I think it works on all the 4.6L Mustangs. Maybe also the 3.8's. Someone else probly knows for sure...

just not with an O/R X. if you get an o/r pipe, get the LMII's. that combo sound wicked.

It works on any fuel system Ford makes with an IAC valve.

what exactly is this IAC mod? ive never heard of it...and are there any down sides to this mod? lol

People shrink the size of the hole allowing airflow in the IAC. It effectively reduces the "hang" of RPMs after the gas is let off. Go rev a carbureted engine--it falls immediately as the throttle plate closes. Go rev your 4.6 (stock). It won't fall all that fast.

People do this mod to get that "old" feeling. Personally, I don't care about it, but each to his own. Someone can probably chime in with more technical knowledge on it (those who have done it) and help out more.

interesting...i dont see how that would be good for the car lol

thanks for the info!

Hell yeah it does! That's what I got and I almost cream my pants every time I start it

Heres a IAC plate on E-bay. It has a couple links to some info about how it works. It doesnt "hurt" the motor. But it may affect smog, seeing as how the idle drops faster and MAY not be able to burn the fuel. Im no expert. Ive done it and love it.

switch midepipes. simple as that. even if you have to have cats, high flow cats and no resonators will wake the sound up a ton.

I was amazed at the difference when I switched midepipes. I went right from thinking i bought the wrong exhaust because it was too quiet to thinking my exhaust was perfect.

the other mods listed are not going to give you what you are after.
