Guys with M&K 2 in 2 out (SSI) ....is it 2 loud...oh my god...mine is crazy...

[nippy]

Just got back from a hour test ride and my ears are ringing.I have a 82 SC,just took off my old Ansa and installed a M&K Sport....the thing is ruthless,I almost feel bad for people on the streets.Sitting at a light is almost embarrassing.

I also did some other mods,been in the shop a week now.Stripped the interior completely,no carpet,no sound pad/back deck,no radio,pulled everything out the front end,no rockers,no nothing!Roll cage was removed because it was poorly done.

Added a MA shaw duck tail,new fiberglass rear bumper,the car feels like a new ride as far as speed goes.But its SOOOO loud.

Anybody else????Can I plug one side to make it quieter or do I need to put the sound deadening stuff back in the car?Maybe dynomat?

Before (Ansa) (yes the 2.7 came off,old pic and thats from previous owner)



After m&K (non painted bumper because the whole car is going to paint later this Month)

I had the same set up Nippy and ditched the ssis for headers it has reduced the noise considerably.The M&K is loud but a hell of a lot louder with the raspy tinny ssis,side by side with my mates car that still has ssis mine seems quiet

[JJ 911SC]

I was thinking of the same combo (SSI and M/K) for a cab

I wonder if SSI and Dank would be quieter

If there is not, there should be a site where you could listen to the stuff

Any suggestion?

[MrPerkles]

The point I was making is people always point at the M&K being loud ,Ive had ssis with a 2 in/out M&K and now with no heat headers.Taking the ssis off made a big big difference to the noise levels.Dansk are more v8 sounding to me but will still be loud with ssis fitted

[JJ 911SC]

The first time my I heard my boss say "Are you with with me"... I going like, well I'm in your office so of course I'm with you... Then the "Penny drop"

Unfortunately with a Cab in Canada... I need the heat so headers with no heat is out of the question.

The last thing I wand to do is install something that would have to come out...

[pmason]

I went from a bypass & M&K 1in1out to headers and M&K 2in2out. At the track the new set up seems loader, but on the road the first set up was loader, but that could be it dumped the exhaust out on the drivers side.

What generation do you have? I think the later generations (4 and on) are quieter. Your muffler looks different (rounder) from mines (though I have 2/1).

[jhora]

nippy...

Most likely it is just the difference now with no interior or sound padding...removing this makes a HUGE difference in the noise level in the car
On the track with a helmet on...no big deal....driving the streets it is very noisy
The M&K is a little louder than the ANSA...but the real difference is no interior
you are now in a large hollow metal can with no soundproofing

[longhornchris04]

I'm with jhora... no sound damping means the body is transmitting all the sound coming up from the motor.

Whats worse, that sound mat not only blocks sound, but also provides an energy absorber to mute out vibrations in the frame. Now the cab is basically a resonating chamber. When I bought my car the engine sound mat had come loose in spots. Replacing it cut the sound significantly.

I'm in the same boat, SSI's & M&K sound good but I have to keep the rpm's below 2k or above 3k to avoid incredible drone, and the idle is loud as well. When I pulled outside of my shop, I could feel the shop door handle vibrate when I closed the door.

I picked my M&K up late last year, how can you tell a gen 1 from a gen 5? After all the work to install the SSI's (Pacific NW, I need heat) I'd like to keep them.

I'm in the same boat I guess, any ideas on a quieter "2 in" exhaust that works well with SSI's to cut the noise level?

I'm a bit spoiled by my e46 M3 set up. I have a Delage Sport intake, with Supersprint stepped headers and a sec 1 with race (200 cel) cats (rear all stock), which turned out to be an ideal set-up. It's almost as quiet as stock below 3.5k rpm's or so, but has an incredible wail when you nail it. I know it's an unfair comparison, the 911 has the rear mounted engine which necessitates compact packaging....

[Gunter]

This comes up quite often.

All 2in/2out have the same problem: Excruciating drone in the mid-2000's.

Tried the M&K and Dansk and had to change to a 2in/1out because I like my hearing and don't want permanent hearing-loss.

2out on the track for performance but not for the street.

[G450X]

Gunter,

Which 2 in 1 out did you go with, and did it really make that much of a difference?

I think I'm quickly headed in that direction, thanks....

[nippy]

Ok with that being said,will trade SSI for true headers,I'm in Fl and we do not need heat....especially right now,NO AC in car...

[mickey356]

I have SSI's and an M&K 2in 1 out and it's fine. Is it louder than stock? Yes. Is it "loud"? I don't know, whats "loud"?
As Gunter said, this comes up often; I've only been of this site a year and it's come up probably half a dozen times. I LOVE the sound my car makes with SSI's and a 2in 1out M&K, but I bought my M&K from someone who didn't like how loud it was on his car with the same set up. It's all personal preference. I think it's safe to say that a 2in 2out will almost always be louder than a 2in 1out.
I guess it depends on what your budget is, what mechanical skills you have and how much time you have but, before you go and buy all kinds of headers and mufflers why not find someone close by with the set up you're looking at and go listen to their car? I got lucky I guess, I'd never heard a 3.0 with SSI's and an M&K 2in 1out but it worked out for me. I don't have $2K to throw into exhaust systems on a regular basis but some folks do and the enjoy the chase of finding that "perfect fit".

[skinnerd]

Had the 2-in GT3 style with SSI's and it wasn't that loud.
Almost too quiet for me.

[Zeke]

I know the performance of the Anza style (that may be another brand) sucks, but I did really like the sound they made. Stock is good too. M&K is a different sound because of the material used for the can. At least this is my theory after being around the cars and many types of exhaust for years.

[nippy]

Here ya go fresh out the oven.....

she still needs allot of work,but I got her for $6K

[blucille]

of course it's loud, you took out the radio

to me (hard to tell without being there) it sounded louder inside the car, since there was no padding anywhere.

a roll of sound dampening padding only weighs a few pounds, I don't see the harm in it, with some lightweight carpet....but with nothing on the firewall and floors, I would think the car would be obnoxious to drive.....I doubt it would be any louder than some of the rice burners and duallie pickups (especially considering the tire noise of those beasts) from the outside....

just throwing my $.02, since I'm about to put SSI's and M&K 911R ver 1 2 in 2 outs on my hotrod....with the stock exhaust (1 in 1 out) it is way too quiet for me.

My 2/1 is not loud at all with minimal droning. I'm able to listen to music when cruising specially with the windows up. Loved those ANSAs sometime back. Had them on all my cars.

[nippy]

the Ansa is on ebay if anybody is interested....
