I have been looking for a new product for a while. I currently manufacture 13 parts for the 914-6 market and wanted to do something for the 4cyl market. I have waffled for a couple of years on 4cyl mufflers and think I am ready to commit to making some. Would even offer a group buy . what I am thinking of offering is a 2in 1 out similar to a 914-6 muffler. They would be 6" diameter, 2.5" tail pipe and I would start by making the most popular set up voted by all of you. So if you were in the market for a quality stainless muffler would it be for a 2.0 or a 1.7/1.8?

I also should note I am not looking to compete with anyone here so would only offer it with standard tail pipe location. There also would need to be someone commited to testing one of them as well as I don't have a 4cyl car. And dad's car won't be drivable for years.

Attched are some pictures of my 2 in 1outs we made for the 6 cyl cars.

So what say all ?

2.0L version for me.


I would also be willing to be the test subject if needed.

I'm sure my flow path is different than what you would do but my 4cyl muffler is available with a left exit in the stock location.

Ben,

This is good news for Type 4 owners. I hope this works out for you. I would be interested in the 2.0 configuration with the outlet in the stock location.

When you say 2in-1out, I hope that means 4in-1out, which will connect to 2.0 type heat exchangers.

Yes. 4 in 1 out


Chris yours would be the high hp setup. Mine would be the more traditional setup.. I don't want to compete with your product line

I understand that yours is intended as a stock replacement, and will only fit 2L HEs anyway.
Mine is designed with maximum flow capacity, and has a high end price-tag to go with it.
My EVO4 rightly competes with the Scart from Europe, and honestly I don't know why anyone would bother importing that one with mine being available. I'd be willing to bet that mine not only sounds better, but offers more HP as well.

Great....

I have a Tangerine exhaust on one of my cars and LOVE IT!!! Wouldn't change it.

However, Ben...I'm IN on your proposed exhaust (2.0) for my black 74.

Need more details and pricing as things develop.

I would think that the demand wold be for the 2.0L type. Be ware that the 1.7 had two variations, one for the early snow plow deep valance and one for the 1.7 shallow valance.

The difference is the exit position of the tail pipe on the left side.

I have an original 1.7L early which you can have for the shipping cost.

The 1974 1.8 muffler had larger pipes like the 2.0L but with the 1.7-1.8L flange pattern.
What would be helpful is to get one installed and make a sound clip of it as many owners are concerned with the sound. Some want loud ( not me ) and some want a powerful deep tone.

Anyone see a problem with using a larger pipe more free flowing unit on a stock 1.7L Wil reducing the back pressure have any negative affects ?

What is the target price?

I am interested in the quietest 2.0 muffler with stock outlet location I can find. Look forward to seeing how this progresses.

Exactly and agree 100% we can talk a bit as this project unfolds again don't want to compete. I see a void between your wonderful products and the triad exhaust which is currently shelved..

Yes we need to test these for sure. I will need a couple of folks to step up and we can work something out to make it work out..

Price point not sure yet.. My group buy for the 914-6 muffler was in the round about price range of 650.. We will see though as I had 10 to make that work. The 914-6 rally mufflers I make at 1k but that is a very special muffler and again now approach what Chris is doing and that is not my intention.. We. Have to small of community to compete against eachother.

I have had allot of pms on this. Here is the deal

I need 2 people here to commit to the following

1 2.0 muffler sent to me for mock up and a commitment to buy the 1st prototype at a fraction if the retail cost TBD, then test the muffler and give feedback. Your orginal will be sent back when mock up is done.

2nd the same for a 1.7/1.8

Please not tail pipes will rotate and clamp on so this will help with multiple fitments.

Thanks Everyone for the feedback.

What about a two in two out for a 2.0 stock HE ?

That'd be my vote.

See how this snowball's.. I am not sure on that.. I think the custom tail pipe locations wade into Chris' area..

I have a stock 2.0 exhaust set up I would be happy to let you use.

I'll PM you.

Mike

Sounds good and to clarify I trying to fill the triad void.. I will not allow it to be competitive with Chris and tangerine. His system fills a perfect niche for hi performance applications.

Are you going for more of a stock sound, or a triad sound? I have a triad on my 2.0 currently, looking for something other than a bursch for my 72 1.7 Still have the original muffler if needed.

Close to stock sounding is the goal with a bit more tone.

Just a quick update.. So far nothing. I haven't received any samples so this is dead unless I have some interested folks in sending a sample muffler.

PM sent

Just to be clear still looking for samples = will continue on project.

Have you reached out to Brad or Garold Shaffer whether they may have some old ones you could use to check figment?

I can send a stock 1.7 if you need it. I wont need it back. I don't have any 2.0 mufflers.

I have a liestritz 2.0 muffler I can lend you. Let me know..

A as stock as possible 1.7 and 2.0 would be great. I really need to know my constraints from a mount up stand point.

Ideally some one sends one that wants one so we can work together on the development.

Still not seen any samples to get this project started.. I really want to do this but need that commitment from someone to work with me on this.

1.7 muffler is being delivered today so making progress.

I purchased a prototype 4 cylinder muffler from Ben a couple years ago. It was a really cool piece. When I decided to go six, I sold it and now I believe its with Zach. I'm surprised more people aren't jumping on this. Lightweight, cool looking, stainless...

I will be in the market for a 4cyl performance muffler for my '72 1.7L. Trying to convince myself out of dropping $1K for a SCART system now that my car is finally running.

As Stone mentioned, there is a difference in exit pipe location. I installed a late 1.7/1.8 rear valence on my car and my stock tail pipe is slightly further inset than the late valence cut out.

An interesting concept may be to offer an adjustable tip that can slide to the position of either cut out location. Some people that don't run a rear valence may not like the sight of a slip joint but I would rock it with a decent looking clamp.

There are lots of possibilities.

The tail pipe will definitely be adjustable.. Thats a given for this product.

I did get the muffler yesterday so 1st thing is to draw the flanges up..

1.7 please.

Flanges for 1.7 are done prototype coming..

Update.

Doing a 1.7 sport looking muffler and will post pictures next week.

Still need a 2.0 muffler as well for mock up..

if you could make an exact copy of the factory 75 76 muffler that would sell for sure.

Funny, I purchased your 1st 4 cylinder muffler about 8 years ago. I think Zach/Vacca Rabite has it now.

Here is the 1st one. It's for a 1.7 Click to view attachment Click to view attachment

Pretty darn cool.

A very cool looking piece but what's it sound like.....a wet fart or a throaty ramble! A good sound track video with a firm price point will help sell these.

Interested in reasonably quiet 2.0L setup. Will keep an eye out for details.

I make a 4 in 1 out that would work for you. I don't yet have the 2.0 mufflers done.

What’s involved in getting these in a polished finish?

And do the twin pipes clear a rear stock narrow valence?

They look great BTW.

Now there’s a reason for the four cylinder cars to go valance free.

I have a stock 2.0 muffler from 1973 that you can have. The baffle inside is loose. If you handle the packing and shipping I will drive it down to the local UPS or whatever. Or you may not want it.....I can send picture tomorrow if it ever stops raining here. No offense to Chris but healthy competition is good for everyone. I would love to have the most stock looking highest horsepower gain best sounding exhaust pipe available that I could afford. Jus' sayin'.....let me know if I can help.....
All the best,
gg

That would be great.. Thanks. Let me know.

Looks awesome! I have a 1.7.... just saying

Very nice Ben...
I have just the right size test platform (914) available if needed.
It was recently added to the "team"
