The 40s will make it sound like everything else on the street and will be very loud. Go with the Magnaflows, they sound good.

Don't worry - it won't sound anything like a mustang with the flowmaster mufflers. Check out Nathan Plemons C4 (long tube headers, x-pipe, flowmasters):

This is one of the best (and meanest) sounding C4's I've ever heard.

i just got my magnaflow mufflers on today with the magnaflow x-pipe, and its still real quite and its not loud at all. i mean it has a different exhaust note and sounds different but its no were i thought it should be. should it be this quite with a new x pipe and mufflers, or do i have to put different headers and high flow cats if none at all on?

I had magnaflows, and got rid of them because they were too quiet. If you want it louder, your gonna have to change out those mufflers.

Flowmasters, Hooker aerochambers, B&B, or Bassani. All of them are louder

My new to me 94 came with muffler eliminators.

I dont mind the sound,,,,,, is there a performance loss/gain with the backpressure completly gone?

If you have to keep the cats, you could even try pipes only and see if thats too loud for ya. It'd be a cheap trial, anyway. I've read some favorable reviews on the board about the chambered muffler system too(I'm sorry if that brand was included in the above list, I don't remember the brand name).

I guess one important question, stock cats or do you have hi-perf cats? I've never listened to hi-performance cats, so I don't know how they affect the sound.

Well, as I understand it there is a "sweet spot" for each motor where you'll get the best combo of torque and horsepower. As you lower the backpressure, you tend to gain horsepower, but lose bottom-end torque, of course only to a point. Eventually the HP gains are much less than the torque lost.
And the reverse is true the other way, of course only to a point, then you start losing both.

Without dyno tuning, though, its probably a craps shoot.

Personally, since I'm not a pro racer or nutin', I look for an exhaust that sounds good to me and call it good.
