I am looking to replace the exhaust muffler system on my car and need some guidence on whats available for the 914 2.0 and what would be recommended to get the best sound and performance from the car. I have been looking at the Manza Exhaust system but I am not sure what if any drawback thier would be to installing that type of muffler system.

I had a Monza type ehaust on my 2.0 when I bought it last month and it was heavy and loud. Personally I like the Bursch that most 914 owners recommened and I am very happy with the system. It's light and sounds nice. It is well engineered. I am converting to a 1.7 system and this will be avilable soon. It has perhaps 100 miles on it.

Pelican and Tweeks sells them new.

Hi Jim! Glad to see you posting!

You can do a search of the archives. However, for cost and performance for a stock/street setup, the general consensus seems to be that the Bursch muffler is the best value.

There are stainless mufflers out there... bring money.

Hope this helps,

SS HE's and the Bursch muffler seem to be the best bang for the buck. you may pick up a couple hp. sounds nice, IMHO -- nice low tone without annoying resonances.

i keep hearing bad things about the monza, others may chime in. it sounds a bit raspy for my tastes.


or, put a header on it!

Where will you be listing the muffler (Here, Ebay)?

Well it sounds like the Bursch muffler wins. The muffler on my car is functional but I don't know that I care for the sound it puts out and besides that it is all rusted looking on the outside. What is the standard muffler that came with the 2.0 914's?

Come to Marina A/X and listen to my Bursch on the 2.0 for yourself. I like the sound it makes on decel under load.

Nice fit with the chrome tip out the stock valance slot.

Hey...I'm 300..Stand up and be counted.

I have it in the classifieds w/this club. I am confident the buyer will be pleased.

Hmmm....No mention of the Triad exhaust? I thought that they were the 'shizzle'

I probably should know this but where is the Marina A/X

Thanks everyone for the feedback.

Nice looking Exhaust setup. It looks lighter than the Manza Exhaust .

I've got the triad system. I like the sound and the looks.

Yep, me too. Swapped out a 4-tip Monza for it, and haven't looked back since.

You can't beat the sound, the look, and the construction. Mine was made by the late David Said; good man, and great workmanship.

My vote is for Kerry Hunter Headers. Beautiful workmanship, great sound. I've already have a set of his 914-6 headers for when I do my engine swap.

headers are ok unless you need heat.

whatever setup you get (I recommend the Bursch muffler), make sure you keep your stock system since I believe you have to get your car smogged at least one more time.

What part of Antioch are you in? I'm off of Hillcrest & Sterling Hill

I noticed Performance Products sells a Sebring exhaust for around $120. Piece of shit? Anyone have any experience with the Sebrings? Looks like both pipes run into a single muffler then the tailpipe goes out the stock valance spot.

I do like the balance look of the Triad system with the two tail pipes. That is one of the reasons I was looking at the Monza setup but I havn't heard anything good about it. What did you have to do to modify the rear valance for the tail pipe on the passanger side.

Ya that is something else else that I was wondering about. Just how much modification one can do and still stay smog legal.

I live on Pronghorn Court just off Asilomar road.

an other view of the Triad Exhaust.
Nice sound, nice construction, more HP due to large tubes increasing exhaust flow ....

don't the bursh systems rust out about 5 min after your first drive? I know mine seemed to.

I heard some have been all rusted up before they come out of the box

Maybe I can get a Triad for farthers day...

do you still have the late style heat exchangers. that type limits your choise of muffler setups. with the smog talk i presume you have a 75'.

kevin

Geeze Kerry, first your car is Ravenna green like mine, now you want a Triad like mine I say go for it, I love mine...what I'd really like is to JetHot coat it in a bright silver color. I gave up on my exahust tips, they were bolted on and just about came off on the track a couple months back, haha.

Rouser: What kind of tips are you using? Mine were/are 2.5"/3" in/out and were bolt on. Maybe I should just get a friend to weld them on.

BTW here's mine w/ the old tips and no valence:

Nathan,
I trimmed my tips about 2 inches, then put the tips on, screwed a sheetmetal screw through them (2 on each) there's no way mine are coming off, even without the screws they are on very tight.

Nathan, I need some additional photo's of you car so I can get it right

Let me know when the NOVA/MD/DE guys get together again.

Cheers
Kerry

Just make a cardboard pattern of the current notch, than copy it on the opposite side of the valence panel. Using a saber saw, carefully cut out anything that doesn't look like an exhaust notch and Presto!, dual notches.

I gutted the mounting hardware from a pair of APC muffler tips (similar to 157820; I don't have the actual part # with me). I slipped the ovals onto the ends (like a glove), drilled a hole from underneath, and tightly mounted them; they ain't comin' off.

Look fine ... lasts long time.

As far as I know the heat exchangers are the original one's that came with the car. My car is a 76 which I still have to get smogged.

I did the sebring exhaust as i was monetarily disadvantaged, the old muffler was blowing out acorn shells. it needs a support for the muffler or something to keep it from "flopping" about unsupported. i used some plumbing strap. ghetto, but until i wear it out and can get a triad....

If you've got a '76 and you're in California, last time I checked Antioch was still in Ca, you're screwed as far as any mods and being smog legal. You need to have a cat and an egr pipe attached and functioning. None of the aftermarket exhausts I have seen work right for 75-76 smogged 914.

That picture of the triad exhaust scares me. How can they tell you you'll get more flow when all the gasses have to pass through that one small pipe in the middle? Anyone seen any actual dyno sheets on any of these exhausts you're recommending? With the exception of a header system, ie no heat exchangers, the best set up is the stock 2.0 muffler. A few years ago we did a bunch of dyno runs with the big aftermarket mufflers and they all fell short of the stock ones. Then we cut a 2.0 one open and gutted it like the 911 sport mufflers and got I think 1-2 more hp. That's it.

However none of this even applied to the 75-75 generation cars because the heat exchangers are completely different and they make the exhaust do an unnecessary 180 degree turn right after the head.

'cause it's louder???

If I meet up with Jim this weekend, I'll have a look at his exhaust to verify if it is stock or not...the PO, might have 'known" somebody in the smog arena to get it passed............

I had a smog legal Busch on my old '75 (sorta, the EGR fitting/port on the exhaust was not drilled...I guess it was "optional" ???? )

It probably wasn't an original California car? I've seen quite a few variations but these days the smog guys are realy picky and enthusiasts get no love.

I heard an unqualified rumor that the state was going to change the smog laws soon to allow no smog checks for 76 and older cars but I'll believe it when I see it.

What about having no muffler and having just megaphones or straight pipes out the back. How is this performance wise, does it gain or loose HP.

i don't know about hp +/- on your car (w/megaphones), but we can hear you coming . jim, with the late stye h.e.s you are limited in your muffler choises.

kevin

The Triad looks very nice. I like the dual outlets.

My personal preference is all factory. From everything I've seen it's pretty hard to beat. The 2.0 "hotdog" or "banana" muffler is basically the same as the venerable 911 muffler, which is pretty darn good from a performance aspect.

The Monza shin cutters are pretty loud and heavy.

From my experience, louder feels more powerful and usually isn't.

I would like to see a dyno comparison of:

Stock H/E's and stock muffler

SSI's with stock muffler

And then each of the aftermarkets with both stock H/E's and SSI's, Bursch, Triad, Monza, and then Kerry Hunter and Racer Chris' set up (which looks very nice).

Maybe when I get an extra $50k or so to spare (yea right) I can pop a dyno in the shop.

PK

ps How can you tell someones a 914 "oldtimer"?? From the scars on his shins from the Monza exhaust tips!

Grassroots Motorsports magazine did dyno a 2.0L with SS heat exchangers and stock and Bursch mufflers, Kerry hunter Header and muffler, and Tangerine header and muffler. Not much difference between stock and Bursch, just plus or minus a horsepower or two here and there on the curve.

I have copies of all the original data.
The Bursch actually fell off quicker above peak hp than the stock muffler.

No muffler is so loud to the point of being undriveable. You also loose low end torque.

Mittlemotor Stainless Steel - last muffler you'll ever have to buy and it sounds GREAT.

Jim:

Do a search on Pelican 911 BBS re: "smog test" or something like that and you will see the a long thread re: latest discussion concerning the proposed changes to the CA smog laws. The latest legislation (authoried by a Bay area legislator) that is on the way to being passed is that the rolling 30 year law will go away and that only 1975 and earlier cars will be exempt from smogging. If this passes (seems likely) it will be a real bummer for me too since the rolling 30 year exemption was one of the considerations that went into my decision to buy my teener this past February.
