911R sound from a 3.2?

[Eric Hahl]

I'm curious if its possible to get the type of sound from a 911R out of my 3.2. I currently have SSI's and a sport muffler that sounds pretty good but honestly, I want it raw and loud, lol.

I noticed M&K makes these:


and this:


Does anyone have any sound clips with either of these mounted to SSI's on a 3.2?

Any advice?

Found this clip with that muffler.


And this one:

I have the old GLH premuffler and muffler on my 3.0 and it sounds louder than both of these imo. I kinda love running it up to redline hopping on to the freeway on the way to work. Ear to ear grin!
alas, i don't have a sound clip of it yet.

If you want that sound, you need to make some big changes which are not inexpensive.

A 906/RSR sounds like that due to camshaft profile, compression ratio, headers and megaphones. Racing exhausts like that work from 5K+ to 8K+ and simply kill power below 4K.

Not good at for any street cars.

Don't shoot yourself in the foot by installing a pair of race mufflers without a balance tube; stick to a dual-in/dual-out sport muffler of choice.


Naturally, JMHO.

Steve, I knew I could count on you for "sound" advice. Thanks.

You are trying to copy a small high reving motor with a 3,2. Not sure if that is possible. But a two in two out factory style sport muffler with headers may be close.

Its possible (I've done it for 35+ years), however the engine configuration requires substantial changes and some of them can prevent smog compliance.

Unless one is willing to spend a good deal of money, adding a GOOD sport muffler will get you as close as possible.

Smog compliance, what's that? my car is of an age that it doesn't need to be run through the sniffers anymore

I like the sound of a 3.2

Headers and 2in 2out m&k. I think I'm one of the few that thought it still wasn't loud enough. Shelved the m&k and went with this for a while. Now it's loud

Those M&K race "mufflers" are deafening. I mean excruciatingly loud and not in a good way like megaphones are. I once had a competitor that chased me during a race come up afterwards and tell me how loud they were, and this was in a paddock full of race cars with straight pipes.

This is the sound I was chasing... Around 3800rpm

Eric,
Here is a clip of the first start of mine, 3.2 w/SSI's, on a car I sold. I don't know enough about the true sound of the R, but I loved that muffler. I regret having let it go, to the point that I'm having Brian make me another right now for my current car. Good luck with your search!

I have a M491, with B&B headers into GT3 Muffler, with electric cut out for straight exhaust when desired. Can't get much better sound than that!

Sounds great. Was that a stock Carrera motor? (except the exhaust)

Yep. I was informally voted "loudest car" at a DE once when I was running these. They sound menacing at idle, but at 5-6k rpm they are just plain loud.

Completely different! The two separate mufflers, won't get you that sound.

Not sure you will get the 'R' sound from a 3.2, but sure you can get a good sounding and more importantly, good performing setup.....Having camped close to this car at Classic Lemans, it sounds amazing:

See if you can take a ride in a cammed non CIS (carb/efi)3-3.2l with SSI's and an M&K 2/2. It should be close to what you are looking for. The M&K also makes the exact same "wail" as pointed out in post 11 when near a wall or a concrete divider, just like in the vid.

[jager911]

I use the M&K sport muffler on the street and when I want it loud, swap to megaphones for the track.

I gotta think a lot of the cool sounds come from the air entering as well as leaving.

That high butterfly or slide throttle business that little wallet guys don't get to play with. :-).
