i guess you can call it an 'early' version, but it was also done *exactly* to my request

i wanted it to look just like the factory sport, but i wanted the pipes w/ a certain spread. in addition, keeping the pipes that long would look funny if they were skinny, but then the tubing that ben uses for the 2-out side exit exhausts would be too fat. so i asked ben to make the pipes' diameter right in between the two. slightly bigger than factory, but smaller than the 'bullhorn' style tubing. it took a bit longer for those tubes to come in, but it was worth it.

Shipping is affordable enough (IMHO) to have Ben send you a muffler without the exit pipe(s). You could then attach the muffler to your actual car, mark the exact spot(s) where you would like the exit pipe(s) mounted and send it back to Ben for final fitment.

Ask me how I figured this out...doh!

Anyway, I have an M&K 1 in 2 out muffler coming my way that is basically like the one on jwernquist's car posted above for my 1987 Carrera 3.2 with stock heat exchangers and CAT.

I already "test fit" it and drove it up to the German Auto Fest a few weeks ago. The thing sounds menacing. It is VERY deep at idle and low RPM's (kinda like a really good V8) and it sounds like a 911 RSR at higher RPM's.

My neighbor (a car enthusiast) and son-in-law say that it is not too loud with the double exit, but it did set off a couple car alarms over the one weekend I drove it... It does not bother me in the least, however, because my car is basically used for spirited drives and I could care less about noise level or comfort. It is a heck of a lot quieter than a Harley.

I can't wait to get it back. I will post pictures in the next week or so.

Thanks Mike! Ben suggested that and it sounds like that process worked for you. So, are you saying you drove it with the pipes tacked on, and now the welds are being finished? Love to see some pics when you get it back.

That's great Ben! Just give me a call when you actually have something and we'll work out payment and shipping.

How does it sound? I think we probably have similar engines.

See my whimsical description earlier in this thread, and Mike's (Momo3.2), who's described it perfectly I think.

It is very aggressive. Not for the faint of heart. If you don't like getting attention, consider a quieter option. Consensus of everyone I've polled is that it is loud, and you hear it coming, but it's not obnoxious loud. Nowhere near as bad as a Harley. But it may set off some car alarms.

Honestly, the sound of this exhaust with this engine is one of the most glorious sounds I've ever heard. It gives me shivers it's so good. And on a track--good lord.

Depending on how stripped your car is, it may make it difficult to listen to the radio or have conversations. But since my car isn't set up for the street and I have no soundproofing or interior save an RS carpet kit, I pulled the stereo altogether. Don't need it; saves weight.

Also, it's very light. And it looks awesome too. And it won't rust or chip.

Also, although I wasn't able to effectively compare driving with the previous exhaust, my suspicion is that this muffler has helped free up the revs even more. The throttle response on this already very sharp MFI engine is ridiculous. In aggressive driving situations, you have to think fast when it comes to shifting.

In short, I see no reason to ever contemplate any other exhaust for the life of this car. It's perfect, for my purposes. If you want something more sedate, for street use, consider some of M&K's other options. You can't go wrong.

Nope, I gave Ben some measurements and had him complete a muffler based on that. Through no fault of Ben's (his finished product was PERFECTLY accurate) the pipes were off center by about 1". The muffler looked beautiful. It was just not perfectly centered and that measurement is critical with a center exit exhaust. Although I thought my measurements were spot on, they were not.

So, to answer your question, my experience was with a finished muffler.

I was able to send the muffler back to Ben with the actual location (relocation) of the exit pipes. So, things should be perfectly symmetrical now.

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.....?

A film of carbon builds up on the inside of the muffler softening the note a bit.

Bringing this back to life....

I have one of the GT3 Style ones for my 3.4 with b&b headers. It is way way way too loud. I am almost embarrassed to start it up. Yes, I like loud motors.

What can I do to calm it down a little? I believe the two outlets are not "mixed" in the muffler. I believe it each tip only sees flow from one bank of cylinders. This makes capping off one of the outlets not an option.

Cheers

Jeff: Have you tried calling or e-mailing Ben? I'm sure he'll be able to help you with a solution.

Nope, not yet, just wanted to see what some had done if they thought it was too loud, besides selling it, which some did.

Cheers

Absolutely love my one in one out...I also have a cat by-pass...wife thinks it is too loud, I think it sounds like a lucious big block V-8[img]

Hey Jeff,

I don't have M&K (sorry Ben), but I did have a very loud exhaust problem with my free flowing B&B dual out. Having a cab and always worried about my neighbors, I added a couple of silencer end caps for about $10 each from ebay. Those silencers took the ID from 3.5 to about 1.5. A buddy of mine actually installed them and had to do some minor modifications (shorten the silencer pipe and make them slightly oval) to make them fit. They attach with a single bolt and can be removed anytime in seconds.

The result of this inexpensive solution did not make a dramatic difference, but they did take the edge off of my loud exhaust. I actually like an aggresive exhaust tone, but I didn't like the embarrassment of others thinking I had a hole in my muffler. I can drive in my neighborhood with a little more confidence and listen to the radio with my top down.

I was also worried about losing HP by restricting the flow of the exhaust with these silencers, but the strange thing is I actually felt like there was more HP with the silencers. Backpressure? I have no idea, but I am keeping them on for now.

Good luck in solving your loud exhaust and I think Ben can help with his silencers.

.. that design just does not work well . we do have inserts that jerry can get you. We have made huge advances with the newdesigns but unfortunatly we did not do anything with the B&B design setups as we built 4 of them or so and felt that design was better left alone. sorry! I wish I could help more

[kimlangley7]

Back in the day... 1967.. 68 .. I had a Honda CB-250.. the "250 scrambler"... that came stock with straight pipes > upswept on the left side.. It would absolutely howl when shifting from 1st to 2nd.. the sweetest.. loudest howl ...

My M&K 2in/1 out reminds me of those glory days... sweet sound >> I love it

[Jeff Alton]

Thanks ben, I will drop jerry a line and see if he has th inserts!

cheers

[nameisbauer]

I love mine.

Loud is good.

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!!

I've had my M&K 1 & 1 for 1 1/2 years, with the FAb-speed pre muff and SW chip. And I still LOVE IT. I get comments from non-Porsche people....Heck these aint even Car people, who like the sound.

Inside the car it has a nice tone, not at all intrusive (and mine is a Targa).
Tha answer to your question about regretting the purchase is......I'm Still Happy.
OH, and I'm not a kid with a need to be heard, let just day....my kids have kids.

[oldschoollear]

what setup would you guys recommend for my 1985 Row coupe?

[Duane V]

Hey Jeff
Sent you a PM regarding your muffler

Cheers

The car is loud. Sometimes too loud for my taste. But it does sound good - truly like a race car. I have a 2 in 1 out with SSI headers. I used to have a 1 in 1 out with a Fabspeed cat bypass which was a bit more quiet, but not nearly as good sounding. I wish it could be a bit quieter, otherwise I'm extremely happy with it. The light weight, the build quality, the stock appearance, all great attributes.

[mb911]

if purchasing now the gen4's are available and cut sound considerable.. Jeff to be honest your best soultion is ditch the B&B's and use georges euro headers and a 2 in 1 out muffler of your choice.. Thats what I suggest to all my customers

[Rad Hatter]

Very very happy rthe sound is just amazing _ get great feedback and find the sound a major motivation to go for a drive late at night in the many tunnels here with the windows down...
