How do you like your M&K? (after some time has passed)
 

I have seen many, many threads praising M&K mufflers, but I'm wondering how folks feel about them after a year or two has passed. Do you still enjoy the sound as much as the day you installed it? Has the novelty worn off?

I'm planning to do an exhaust upgrade to my '89 next year (Fabspeed Pre-muff, M&K 1-in-1-out, SW Chip), but I've never had an aftermarket sport muffler on any of my Porsches and I don't want to find myself regretting the decision a year later.

Thanks in advance for your commentary!!

it's a bit louder than whatever "sport" combo you get from the store, but it's a nice loud...

what's not to like? superior materials, welds, and support. custom to your liking. light as hell. you can request it quieter, or just add some extra sound pads to the rear. you cannot take out the weight out of the other muffs...

I've lived with my 2 in 2 out since 11/13/04 and I still love it. I did purchase from M&K the tailpipe "cap" to close off the passenger side tailpipe for everyday use because for me it's a little too loud for everyday use but great for autocross or DE when uncapped. I also have SSI's if that matters. For the quality,performance,sound and weight savings you can't beat these mufflers.

I love ths sound of my 2 in 2 out muffler. I smile everytime I hear it. When not driving the car I crave the sound the car makes at High RPM's. I just need to get more miles on my car and I would be extremely happy.

I agree with everyone else. Super quality, service and very lightweight.

I like mine every morning when I start it. A Ferrari guy told me it sounded really good. I have fabspeed euro and sw chip. r.t.

After six months I still love my 2-in/ 2-out. I have not met one person who doesn't like the sound. What I like most is that Ben is willing to make any modification that I want on the exhaust that is already on the car.

that 6000 rpm wail is my crack pipe

Agree with all of the above. No regrets.

An added bonus is that after about a year or so (depending on how much you drive the car), the muffler will begin to "cure" and the sound becomes slightly more mellow. Not quieter, but mellower. The only way I can describe it is that any "brittleness" that existed when the muffler was first installed is now gone and the sound is very rich and pleasing. Others here have commented on this as well, although I can't seem to find an explanation for it.

Any ideas Ben.....?

I like the gurgle of the 2 in 2 out Sport at idle and the backpressure on deceleration.

I have one of the GT3 style variants....and it is actually almost too quiet.
At the track everyone comments how quiet it is.
They do say it sounds good though.

I'm almost interested in finding out how I can make it a bit louder.......:eek:

Really like the light weight, fit, finish and sound.
Just louder next time.:D

at every track event i've been to in my car (2), i have always been told by many (most) that my car is the best sounding there.

I am actually the opposite of everyone else here.
i really liked the sound of my 3L with SSI's and a hollow flowmaster.

i expected the same thing but more with my 3.5L B&B's and M&K dualy...... the entrie thing was different....much "nastier", but after about 5 days... my opinion changed.

that is also the first time my engine saw more then 5k, and i believe "blew" some of the insulation out. its seriosuly loud.... but i was told it would be.

it looks great, it weighs very little, and i can't imagine a better sounding engine......

Any 1 in 2 Out with Stock Exchangers ?

I have the 1 in 1 out with cat by-pass on my SC. Whenever I start it in the garage, it startles me with the raspy loudness! On the open road it sounds great and seems to pull harder throughout the rpms...compared to the stock muffler.

No ***** ! I love the sound of mine - drove it 2.5 hours to the track, several hours on and then drove it home. The best part was listening to the sound of McKenna shifting from 3rd to 4th on the main straight - my first time hearing it on the track! Most of the time the radio is off, I just love the sound of the 911 w/M&K.

Still love the sound

After debating for over a year on whether to go 1 out or 2 out, I finally installed a 1 in 2 out on my Carrera this past weekend. The muffler is not as loud as I expected - I've got no sound padding at all in the back seat or engine compartment and while I still hear more 'motor' than exhaust, I absolutely love it. Once the revs climb, that raspy wail is pure sex. I am falling in love all over again with the sound of this motor.

I have a 1 in 2 out with a cat bypass and I love it!! The sound is fantastic with the top down and you don't get any low pitched drone at normal highway speed like some other mufflers do.

I'm undecided on my 1 in 1 out. I love the weight of it but after about a month on the car, I'm growing tired of the loudness. The sound makes me wonder if I have an exhaust leak. I plan on pulling off the cat bypass and muffler to look for evidence of a leak. If I can't find a leak, the stock muffler may go back on.

I've got a 2-in, 1-out on 993 heat exchangers and the sound is intoxicating; rumbles like a big V8 at idle and sounds like a modern Porsche race car engine when pushed. Like many, I've received numerous compliments on the sound (on the street, AX, and track). My only negative comment comes from my wife who thinks it's too loud. The build quality and weight are both big bonuses.

My 2-in-1 out sounded awesome and was top quality - just a little too loud for my standard 72. Less than 200 miles later I ordered a OE Dansk to replace it - I'm very fussy though.
