WHat is the loudest exhaust?
 

I saw another thread where the person stated they want throaty exhaust but not loud enough to set off car alarms and scare people away.

Well, that IS what i want! :)

So i got a 2004 Mustang GT, i had the H-pipe cut out and had a custom 3inch X pipe welded on with straight pipes catback. with 3 1/2 chrome tips. No mufflers here baby!

It is loud yeah, and i absolutly love it, even the popping after you you rev it up and let off. Burly. I know, some say redneck exhaust, but i like what i like ;)
Id DOES drone at highway speeds, but i dont take the highway too often. I plan on running dynamat under the carpet, in the doors, and in the trunk anyways, i figure that will cut a good amount of the droning out.


Tell ya what though, i have never set off a car alarm. I have a co-worker who had a Dodge Ram 1500 with straightpipes and when he was pulling out of the parking garage he could light up damn near every alarm within 50 feet.

WHen i rev it up, that just doesent happen. I cannot nearly hit the DB level that he could.

Granted, i dont want to be pissin off my neighbors when i come to and fro... to and fro, i like using that phrase

none the less, what is the LOUDEST exhaust setup?

Straight pipes was not nearly as loud as i expected it to be

If you want louder get a set of long tube headers and 2 1/2 the rest of the way with the biggest tips you can get or just dump the exhaust to the side behind the front tire. Since you have stock 2 1/4 tailpipe this is why its not as loud as it can be,get rid of all of the 2 1/4 piping.

Open headers! ;)

No headers straight out the heads :D

lol. what these guys said. but if you want it legal..... my setup is the loudest I've heard and i continue to get people on the road telling me that it's loud. It's very nice it higher rpm's but right at about 2500-3500 it can get annoying but I will put up sound clips as soon as SOMEONE TELLS ME HOW TO

Make sure sound clip is not large in file size as it will not work keep it around 900kb. Most of my vids i have to reduce the quality so it looks like crap but the sound quality does not change.

What is producing back pressure for you?

who are you asking?

on my setup the only thing offering backpressure is the cats.

it goes 2.25in to the cats, then goes to a 3in xpipe, goes back to 2.25in right before where it goes over the rear axel to the 3.5in chrome tips.

The effect of this that I noticed? Sounds damn good. I like that poppy sound though, i guess that is just more of a personal preference.

It seemed a little bit tired or sluggish on the low end, but the difference was very slight. On the higher end it seems a bit stronger, but not by a whole lot. After i put in the K&N the responce really tightened back up, whatever i lost from the exhaust was restored and improved over stock, and the higher end is noticably stronger. Nothing jaw dropping, but definatly noticable.

I had my buddy drive it around the block a couple days back so i could hear it. It always sounds different inside the car. <laugh> Standing out while he tore around the block really put a grin on my face though. The stock sound on the GT's is just pathetic if you ask me. Muscle cars are not supposed to be polite. <laugh>

long tubes, some kind of o/r pipe (h or x) and straight through style mufflers such as Magnapacks or SLP's.

Full SLP is probably the loudest setup. However some say its just loud with no substance.

I think its ok but too loud.

My borla sounds good with stock H and headers. I am going to get a MRT H with cats or a prochamber with cats this summer.
