914World.com _ 914World Garage _ GB -6 mufflers in stainless

Posted by: mb911 Aug 8 2017, 07:37 PM

So after all of the testing we have good feed back. The mufflers are quiet as stock and flow a bit better over stock as larger id tubing internally. We still have to tweak the tail pipe locations and may ask for a little assistance with that. I am going to offer 10 of them at 650 for intro pricing and then 900 after that. They will be made 100% of 304 stainless weighs 18lbs, 2.5 dia tail pipe, installation kit will be included, shipping will be extra and to be determined.

Cairo94507(Michael) is 1st on the list so 1 more spot.(deposit )

Updated the list. Please remember I need pictures of the heat exchangers installed on your cars so I can have pelicanparts add it to their website.

Also deposits can be made by paypal =add 3% or by check. Paypal is mbmcfarland6@ gee mail .com. (Gmail.com) these are good for mfi cars

Ben - I just wanted to offer a big "Thanks!" for being one of those who help enable us to build our dreams.

Being a reliable supplier is no easy feat.

You're on the short list of those who meet my criteria of "if I need/want it and he/they make it, I'm sending my money!"

Thanks again, we couldn't do it with out you and our other well known suppliers. Keep up the awesome work.


(And now that I have you nicely buttered up: I have this LS3 build that needs a custom muffler made.... laugh.gif )

I could build you the shell with no inlets but all the internals and you could weld on what you want ? Just a thought.

MY first time logging on in a week...let me know the timeline to get a definate.

I have an old M&K sport I was going to get modified to a 3-outlet rally muffler.
Would it be possible to get this with addition of the sport tips that can be capped?

Full new would be better than modding an older one right?

Nathan

They are 2 different type of mufflers. This one is focused on quiet and slight improvement on stock performance which has proven over the years to be almost unbeatable..

The m&k mufflers are about pure 6cyl porn. They sound intoxicating and build off of that.. Its all about what you're looking for.

Ok so minor seatback but have plenty of measurements to correct now.. I tried it on Georges 73 2.7 with a 915 trans and also his orginal six. Tail pipe needs a true 90 and the angle downward about 30 degrees.. Attached Image

Posted by: live free & drive Oct 2 2017, 04:11 PM

Hi Ben,

What rear cone did the 915 tranny have - stock, Vellios, Wevo etc?

What was the clearance to the muffler?

Jon

Posted by: mb911 Oct 2 2017, 05:54 PM

Vellios..on a gt cloneAttached Image

Posted by: GeorgeRud Oct 2 2017, 08:44 PM

The stock heat exchangers needed a slight elongation (about the width of a muffler flange) to get the stock Leitstriz muffler to fit, but Ben's is slightly smaller in diameter so should fit even with the Vellios tail cone. I think the Wevo 915 sticks too far for any single banana style muffler to fit.

Posted by: Keith914 Oct 2 2017, 10:33 PM

I will buy one for $650 if still available. How can I send the $300 deposit?

Posted by: mb911 Oct 3 2017, 05:33 AM

My only concern with your car is that you run a 915 with the extension s and that may skew the results.. Not that they won't fit the same..

Was it a wevo 915 kit tail shifter? There much worse than mine. Mine is a Martin Bott 916 side shifter. Mine still requires extra clearance, but the Wevo 915 guys typically run short headers with dual mufflers.

or a very skinny M&K muffler.

Posted by: mb911 Nov 2 2017, 06:14 PM

It is the vellios kit.

Posted by: Steve Nov 2 2017, 06:52 PM

The velios is also a side shifter, so it should be the same as mine.

Posted by: mb911 Nov 3 2017, 05:13 AM

Yup thats what I thought.

Posted by: GeorgeRud Nov 3 2017, 09:06 AM

The Vellios rear transmission cover requires a small spacer to clear a stock muffler (about the width of a flange is all), but the Wevo tail piece is much more intrusive. The Martin Bott system should be similar to the Vellios I would think.

The vellios and Martin bott rear cover are both patterned off of the 916 rear cover. However I haven’t seen a reverse switch on a vellios. I have one on mine and it does stick out about an inch.

Posted by: GeorgeRud Nov 3 2017, 09:55 AM

No reverse switch on the Vellios. However, even without one, it does slightly interfere with a stock muffler.

Posted by: live free & drive Nov 3 2017, 11:56 AM

Would it be possible to have added 1 1/2" to 2" to the inlet pipes for people (like me, among others) who are running a 915 trans?

Maybe for an upcharge you could provide the modification vs. having to insert/create spacers?

I'm working on a 3.2 with a 915 and your HE's - I have a Vellios tail-cone, but currently have installed a stock tail-cone (with reduced features) and the PMS steel adapter frame. From my measurements the Vellios tail-cone is about 3/4" shorter than the stock tail-cone casting (measured including nothing beyond the casting surface) so I'm assuming it's going to interfere with the muffler.

Its possible..

The problem is that almost every order I had on the group buy wanted something special or custom and it makes very hard to break even on the project when I finish everything up..

That said its possible on this to do the upcharge as you describe.

Also still have to work out a 911 style muffler hanging installation setup. These mufflers should not be supported just from the inlets..

Posted by: mepstein Nov 14 2017, 10:52 AM

Mine is sort of rigged up the 2.0 hanger. I would like something that looks good and works correctly.

Posted by: GeorgeRud Nov 15 2017, 12:09 PM

Though not elegant, an extra flange between the heat exchanger and the muffler with extra gaskets would provvbably be the easiest way to obtain any needed clearance. Much easier than modifying the mufflers or heat exchangers for those few folks that need this. I wonder how many folks are actually running 915 transmissions in their cars?

Posted by: Steve Nov 15 2017, 01:23 PM

For me and my Martin Bott 916 kit a 2” spacer would be perfect. I agree.. extending the pipes on the muffler will hurt the resale value for cars that don’t need the clearance. Ben made me 1.5” spacers that work, but I had to use studs versus bolts, due to limited space between the flanges on the spacer.

Posted by: mb911 Nov 15 2017, 03:06 PM

Steve once you get the muffler we will have to look at options for a 911 style support..

Posted by: Steve Nov 15 2017, 05:19 PM

Some of the other local six conversions are using a log type muffler that use the straps around the muffler versus the hanger. I will find out how they made it.

It looks like it needs to move over exactly 2” to the right. It’s still on the car if you want me to take more measurements or pictures. Otherwise I can take it off and send it back. I didn’t start the car up.

Something else interesting... I did not use my 1.5" spacer. There was enough clearance without it. However... The muffler is exactly 1.5" from the rear heat shield. I am curious how this will effect WEVO installations, since they typically require a 2" extension since they are a tail shifter.

Here's a picture of the 3.6 914-6 in Excellence. It used 2" spacers with an M&K muffler and a Wevo 915 trans. I think the M&K muffler is a thinner muffler??

I may have you send it to Mark.. otherwise it will work for a later 911 as well and I think I have one customer waiting on that..

Steve please confirm everything else is correct for height and angle and just moving to the right closer to the muffler by 2" will do whats needed.. Once we know that I will send you another one with corrected tail pipe..

Then it should work fine with a Wevo 915, but might have to modify the heat shield. Here is a shot of the rear clearance with no spacers using your heat exchangers.

Moving the tail pipe 2" to the right should be perfect for my car. The angle and height seems fine.

Looks like tail pipe diameter off..

It looks like it needs to move over exactly 2” to the right. It’s still on the car if you want me to take more measurements or pictures. Otherwise I can take it off and send it back. I didn’t start the car up.

Something else interesting... I did not use my 1.5" spacer. There was enough clearance without it. However... The muffler is exactly 1.5" from the rear heat shield. I am curious how this will effect WEVO installations, since they typically require a 2" extension since they are a tail shifter.



I may have you send it to Mark.. otherwise it will work for a later 911 as well and I think I have one customer waiting on that..

Steve please confirm everything else is correct for height and angle and just moving to the right closer to the muffler by 2" will do whats needed.. Once we know that I will send you another one with corrected tail pipe..


let me know or text me later today

Take care of your real customers first.

So long story short. Steve received the 1st one and as you can tell tail pipe was in wrong location. Steve's buddy Keith found out and worked out a deal and installed it on his car.. From what I have been told there are some very positive results.. Boxes are ordered and here ready to ship mufflers.. Mufflers will be shipping starting this week amd all will be shipped by the following week. Thanks again everyone for your patience..

I took a sock muffler bracket and welded the upper support on and use spring tensioned muffler clamps. Its just 1/8' or 3.175 mm thick material welded to the bracket and then heated and bent to the form of the muffler

I was talking with Eric Shae about it and he mentioned the GT style hanger?? Not sure but I heard they worked well.

This was from the fellow in Europe who recently hand built his 904 replica.


That's the one I have started to make ,I want to get rid of the normal hanger support
if the stock muffler (heavy) is supported on its own should be fine ,my headers are very solid.
BTW nice work on the mufflers Ben ,do you intend to go into production ?.

I agree, your headers are solid. Do you think the headers being that strong and the additional weight of the heater boxes might put more stress on the exhaust studs. The hanger would help to eliminate movement at the ends that might torque the flanges.


Posted by: mb911 Dec 11 2017, 06:00 AM

I feel the best solution is to hang them just like a 911 would. This would eliminate any stress on the studs and less likely to break anything..
