i have a 91 rs with a 305 could you tell me witch brand to go with to get the old muscle car sound and tell me what all i need

I belive you are looking for the same sound I am. From what I have been told you need a set of full length headers no cats and your choice of exaust probly a set of glasspacks would help also but the important part is the full length headers cause they are thin and the exaust sound you hear is caused by the thin walls of the header. That is what I have been told If anybody else knows any other way please tell us cause full length is a P.I.T.A.!

My 83 sounds old school.
Here is what I got

406
solid roller cam 242/248 .571/.577
AFR 195 heads
Hooker LT's
straight pipes into Flowmaster 40 series

No glass packs, Flowmaster says muscle car, glass pack says cheap.

Alot of the muscle cars have turbo mufflers on them thats what make the sound. Flowmasters are to hollow and dont produce the rumpity sound. Cherry Bomb actually makes a cheap turbo muffler that produces the sound your looking for but no single in dual out setups, single single.

Remember HP makes sound. You can take out the cat and put in headers and any muffler you want. However, you will never get that increadable sound of a Goat or Charger without the power to back it up. Plus I would assume the high compression that most of these engines helped make the sound.

It depends on how much you want to replace; ideally you'd have long 4-tube headers, full true dual exahust pipes, nice mufflers, and a lumpy cam

Check out this exhaust and the videos.

GMMG

I like it and would buy one if I had the money.

Oh man that exhaust is awesome but seems to be kinda overpriced don't you think? And didn't someone fab something like this up before? I think his name was Willie but not too sure. I'd get this kind of setup but the price is what kills it for me. Guess I'm gonna have to fab it up myself so it's cheaper

"...the old muscle car sound..."

How old?

How muscle?

A '65 GTO had an awesome sound to it - 389, dual exhaust, cast iron manifolds, mild cam. What, iron manifolds? Mild cam? Yes, the big irony is what were called "muscle cars" with their great sound would get tromped by a real "performance" car that didn't sound all that powerful.

So, "HP makes sound", eh? That explains why those 440 Chargers with their quiet turbo mufflers are about .5-.75 seconds quicker than my loud 396 with the Bullets. Time for a reality check.

That GMMG exhaust is a single I-pipe that splits at the axle to two mufflers. No real difference from a single inlet muffler with two exits. (And what's with "Credit Cards are NOT accepted for this Item"? Are they afraid of the fraud cops?)

Want the sound? The factory manifolds with dual pipes to dual turbo mufflers with dual tailpipes will sound pretty much like those old muscle cars. (I'd recommend Summit turbo mufflers over the Cherry Bombs - about $10 less each, and somehow I trust Summit more than CB.)

You want performance? Shortie headers, y-pipe, high-flow 3" cat, 3" cat-back, heads & cam change. It'll run awesome. But, it won't have that "old muscle car sound".

$700 dollars for that is alot of money and it looks cheap not mentioning the $150 tips you could get(not clean looking)

It does sound good but that probably do to the poqer of the cars in the vids.

If you want the muscle sounds just get headers, no cat, 3"-4" pipe, and a descent glassback not the $20 ones.

how much would it cost me to get that sound i have a 305 and dual exhaust

I haven't gotten out of a muffler shop for less than $200 for several years. And that was for a pretty simple job.

You're probably looking at as much or more to get this "sound" as it would cost you to buy a real performance system that you could bolt in yourself.

Did anyone mention the ground clearance you're going to lose with this dual "muscle car" sound system?

- 4bbl carb
- healthy cam
- dual exhaust (no cross pipes)
- 9:1 or more compression

These are a good place to start, but the one thing that changes the sound more than anything else is the heads, and more specifically, the combustion chambers.

I can't tell you why thats true (about combustion chambers) because I don't remember, but it is true.
