Aurora Exhaust?

[97abrora]

I know.. "not another exhaust thread" but after hearing my friends Mustang GT 40th anniversery edition supercharged mustang, witht he flow-master mufflers, I was wondering which mufflers would give my car that loud rumble like his.

He could just turn it on, and you'd hear the exhaust rumble.. pretty nice, and I must admit I like that.


Anyone have any ideas which mufflers will achieve this kind of sound on our cars?

Flow-Masters would. Mind you, they might be too loud at certain RPMs on the highway. Depends on what you want. If you want it to sound healthy but not too loud, DYNAMAX, MAGNAFLOW, CORSA exhaust systems may be the way to go. They won't be too loud while you drive because trust me, if you drive on the highway a lot, a really loud exhaust becomes a nuisance real quick.

In almost two months with the car, I've been on the highway once... I rarely drive on the highway.

So what make/model do I want to buy these for? Nothing for Olds, and only a few for caddilac escalade etc. as I can see no cars are included.

What size in/out do I need? Does anyone have these on their car? I searched, but nothing came up.

You'd buy a Flowmaster universal muffler in the appropriate size, and have a shop install them. There isn't a kit for your car.

As an aside, my car growls when it fires up. Steven's did too when I heard it at Carlisle. He has Dynomax mufflers, and I have Corsa.

What's the apprioate size? I was planning on the Corsa exhaust, but I'd just rather have the mean loud exhaust sound...

What size piping is on our stock exhaust?

im also going this route. i dont want the loud sound or the fart can cause i had a friend who did that to his car and it gave me a headache after a couple rides with him. but i know what your talking about the mustang. its got the loud rumble which makes the engine sound good. i dont want mine that loud but i like it when i turn the car on and when i accelerate.

hey guys, out of all the ones you have listed is the Corsa the best? i like how they look on the car with the dual tips.

You should measure your stock exhaust and then get a suitable replacement. If you have a local shop that will do the work and sells Flowmaster (there are a lot of local places that sell Flowmaster) then you could just take it in to them and let them do the measuring. You'd basically pick which style of muffler you want.

Betonthis1, there's no best. It all depends on what you like and what you want to spend.

is there a basic price range on something like that? if anything i can do myself then i would but i cant do wielding and whatnot.

Price varies quite a bit shop to shop, but the Flowmasters are on the cheaper side for sure, so part prices are not the issue. I think the Delta 40 goes for something like $40-60 each. Piping is cheap, even stainless, so a good shop should be able to wip a set on for around $200-250 max including labor. The best size for any piping after the split is 2 1/4", so just get the proper size with 2 1/4" in/outs. (Before the split, the best single size is 2 1/2", but you only need that if you're going cat back)

The proper muffler size is determined in a very complicated scientific process. You have to get a tape measure and crawl under the car and measure the stock muffler's length and width. The scientific part comes in when you're smart enough to measure after the car has sat long enough to cool down.

$40-$60 retail? I think flowmaster sells them for like $125 a piece.. although their site doesn't have the universal parts.

Theres a bunch of different mufflers. Dynomax Super turbos, magnaflow etc Or you can just cut your mufflers off and still get the throaty, loud sound .

You can find them here for a lot less than the list price:

store.summitracing.com/default.asp?target=/egnsearch.asp&N=400238

In general, they don't sell for what they are listed at on Flowmaster's website. However, you can find their universal mufflers on their site. It's under "Products" and then whichever series you are interested in. For example, here's the 50 series Delta Flows: www.flowmastermufflers.com/50_delta.html

Their site used to be easier to navigate and to get info about what's different about the various series.

Thanks Aurora40.

And as long as we're rehashing (which is cool because we have many new members and some stuff was lost on v2) the only dyno test I've seen with a motor somewhat close to ours, the Ford 4.6L, the best performance improvement was from Magnaflow and Borla XL mufflers. (They didn't have any Corsa's in the test) And yeah, yeah about the Ford mill being close to ours, they didn't test any Caddys and the other mills were OHV GM and Chryslers, so it's as close as I can get.

The loudest of the well known brands seems to be the 40 series Flowmasters. No real performance gain, but they pounded the sound.

Thanks Letitroll98!

How do you know when the exhaust has cooled down? ;D

Well, drive it really hard for about thirty minutes, then park it and immediately crawl under and grab ahold of the muffler piping with both hands. After the screaming stops, wait five minutes and try again. When you complete this proceedure without hearing any screaming, it's cooled down enough.
