Default the sound of your M96

My previous "fun" car was a late 60s Mopar, with a 340. I mention that only so you know my reference point here. Also, these observations are being made from the driver's seat; I don't know what things sound like if I was standing on the road as the car went by...

As a new owner of my 2003 C2, I'm a little surprised at the exhaust sound. At idle, it has a nice little raspy rumble. However, once it gets above 2000 RPM, it loses the rasp and becomes more of a "hum". In some ways, it almost sounds more like an electric motor than an ICE.

Is this just a side effect of being in the cabin?

I had a 1971 Plymouth Duster 340 4 barrel 780 carb, Accel dual point distributor, Crager SS mags with Mickey Thomson wides on the back. While this was back in the day, my C4S will never sound like that thing. However, with the stock exhaust the P-car sounds mild until about 3000 to 3200 rpm then the exhaust note starts to get aggressive and what a lovely sound it is! Is your exhaust stock?

Overall I think the cars are mild but do have a unique exhaust note. Its all relative though, a lot of people say with muffler bypasses or cat deletes say these cars are very loud but I have had my fair share of v8s with long tubes, no cats and a muffler and it wasn't bad. Alternatively I've had cars with just mufflers that drone bad. I keep going back and forth between doing the muffler deletes with some silencer inserts or doing high flow cats and mufflers. Obviously ones way more expensive than the other but I feel like I need something to wake this thing up a bit.

'69 Dodge Dart Swinger, 340, 4 speed, black on black, bench seat. The 340 is, IMHO, a very unappreciated engine. Good HP and great torque from a relatively small block. It's been over 45 years, but I still remember it well.

Yes, our cars are a bit on the quiet side ('02 C2), but the Fister mod will likely give you the aural sensation you're looking for.

You can get more noise by modifying the mufflers. One is called Fister and I can't remember the name of the other mod. It involves modifying the arrangement of the input/output tubes on the muffler. Not all that expensive. Do a search here. I think you will find a lot of info on it.

Gundo is the other modification. Finally got enough coffee in me to get the brain to kick in!

In 1968 I convinced my parents that a Plymouth road runner would be a perfect car for my mother to drive. Yellow with a black landeau top, red line tires, and a 4 speed Hurst.It sounded like a 383ci. with 335 hp. should, until my first day back from college a year later when I wrecked it after meeting James Tayler later that night.

That "convincing" conversation must have been a work of art! Sux that you wrecked it. Fast?

My first car was a Plymouth Fury III, never had a muscle car, but did have a 05. 300SRT 6.1 HEMI w/MF exhaust, it rumbled and roared when you got on it...the perfect family 4D muscle car...I love those old MOPARS.
The 996 is a refined sports car and comes alive in the upper RPM range.

mrfeh, have you stepped on it yet?

Yes, stock exhaust.

No, I really haven't let loose on it yet.

And FWIW, it's not the loudness of the exhaust, but rather the nature of the sound. I've done a poor job describing what I hear, but is "humming" the expected sound in the 2500-3000 RPM range?

I get what you are saying, it has a rumble at start up and idle, seems to get kinda quiet lower but if you wide it all the way out you will get some rasp again. These cars have a fairly unique sound from what I am use to.

Like I said it sings a nice song north of 3200rpm. Not sure about the definition of "humming" but lower rpm is not obtrusive.

Coming from a 66 Corvette 427BB with side pipes, I do have a very HIGH appreciation for the lower sound of my 02 C4s.

My car does have the factory sport exhaust, when compared to a regular exhaust, the sport does sound much better.
