Custom Type IV Exhaust.
 

Hi,

Just thought I would post a few pics of my custom type IV exhaust, I had it built in New Zealand and it is a one off but it may give someone out there some ideas when taking on building an exhaust.

The system has been on the car for a few months now and it is going great. the idea behind it was to get equal lenght headers while keeping the twin tip look. As far as performance is concerned it has smoothed out the acceleration and the bug pulls all the way through to 100 mph. The sound is great as well it is rensonably quiet at idle just a deep rumble, but when you open it up it roars.

The last pics are after the system has been HPC coated.

looks like a nice job. what size pipes?

:agree: :agree: That's what I like -- right through the openings of the stock apron. Y-y-ye-e-e-esssssssss! :D

Hi Guys,

Thanks for the replies... I think the piping is about 1 3/4 inch.

I agree about the tail pipes comming straight out the stock apron holes, it helps with the sleeper look. The beetle is often under-estimated.

:cool:

Exactly!! I love it. Do you know if this style would be suitable for a larger displacement engine, say 2.3 liters? Or is too restrictive?

It sure looks good and I like the fact that it is not really lower than stock. Also the valve covers can be reached easily. Big bonus points there also!
You would almost want it be tested in Jakes big type 4 exhaust shootout ;)

How does the pipework run inside the muffler?

Thanks,
Walter

Hi Wally,

I am not sure how the muffer in constructed as it was made by a seperate specialist muffer shop. When I got my hands on it was all welded up.

I know that it is glass filled.

The height was important in the design because my beetle is quite a bit lower all round. I had a simillar exhaust on the beetle previous but the bad points were the distance below the apron that it hung, (stop draging it on drive ways), the muffler was not supported so it kept breaking manifold bolts.

This setup is miles better. :cool:

Regards submitting the exhaust for Jake's testing, there maybe one small problem... The exhaust is in New Zealand and Jake is not.

I am sorry but I would rather spend the shipping money on other bits and pieces. It would be cool though to know how it stacks up against some of the mass manufactured systems.

If any one is up for sponsoring it, we maybe able to come to some agreement.

I wonder what Jakes thoughts are, it could be a dark horse in the testing !!!!.

:D

This dark horse would be a front-runner on my track if it weren't for the fact it is a one-off design. The current pre-test front-runner is lower than and sticks out from a stock apron -- even before mufflers are applied.

I'm freakin out a little bit here. I really want this exhaust. I'm getting all nervous like I won't see it again. I don't even have a Type 4 engine yet. :confused:
Is there a drawing or a design scheme of it somewhere? Or could I just show someone some pics of it to get the idea?? I want something like this made. :agree:

Hey Paul, cool car and cool exhaust! I've seen you over at aussieveedubbers.com/forum before :)

I hate to cut in your thread....just thought I'd add my bit as I had a custom exhaust made for my type IV in my 63 too....here is a link to its full details (I'd post a pic but haven't quite figured out how to do it yet re. hosting the image etc).

Once again, great looking beetle mate.
Alan

Well, there's this model from LA Performance. I did not receive an definitive answer whether the black apron is stock or not, although it does look stock.

Well, as I really am not able to weld an exhaust up, let alone design it, I'll have to do with this pre-made one from Ahnendorp:

Adjusting valves will involve removing the mufflers (not shown) with this one, but well...

Walter

PaulGrey,

Nice exhaust .. looks like there was some inspiration from Porsche in your design .. well done.


Wally,

Thats the same header I'm running but with a single dynomax muffler. I welded a flange between the header and muffler so I have to undo 2 bolts to remove the muffler for a valve adjustment ... a small price to pay as I am not a fan of having a big muffler hanging off the back of the car ... looked like my bug was dragging around its own turd :laugh:

With my old T1 motor, I had the muffler hanging off the back ... dragging every time I'd back out of my inclinded driveway to the street ... dragging on every speed bump I'd go over ... got really annoying after a few weeks :(

Sandeep

yes, I like your muffler almost better than the elaborate BAS set-up (yours sure is cheaper), but that one you have is really hard to come by over here and I wouldn't have know where to order the one you have got.
For circuit raving we have to have very, very quiet engines these days due to new sound pollution regulations and that is where the BAS muffler set-up excels imo.

Thanks,
Walter

Wally,

Try Summit Racing for the muffler ... currently selling for $49.88 USD ... they ship to Europe ... http://store.summitracing.com/defaul...7676&x=11&y=10

Sandeep

Thanks, that's a steal!

Hi Guys,

Thanks for all the feedback, I am glad you all like the system, it is cool to see some of the other "one off" designs, keep them coming... I guess there are many ways to skin this cat.

I will post a few more pics, shortly... I have no plans at this stage to start manufacturing these as I would have to get someone in New Zealand to do it on behalf, so the cost may be a bit high, I estimate about $2000 NZ... $1397 US + shipping.

The other option would be to have the design drafted and have someone in the states or UK manufacture them as required.

You thoughts and coments are welcome.

I believe this Remmele exhaust is still for sale in the UK.

The Remmele looks ok, it is simmilar to what I had on my beetle before I had this new system made. The issues that I have with this design are that the muffler is not supported, all the weight of the muffler is supported by the heads On my design I included a bracket that attaches the muffer to the block. When the new system was installed on my beetle I had to have the pushrod tube seals renewed becasuse of the load coming off the heads. The second thing would be the pipe lengths, with the longer pipes it alows you the opertuninty to tune the lenghts, If you can get all of pipes to the same lenght or even better to the same CC capacity, then you will achieve a much smoother and efficient exhaust. On the plus side it is stainless... and that always sounds cool.

Thanks to Bill.K for talking me through the posting pic process! As aforementioned, here is my system I had made here in Australia...all primaries are matched lengths and the muffler (as paul notes for his) is supported on the block.

To save posting heaps of pics here, there is a link to the album of the exhaust sytem here:

Here is the sytem part way through manufacture....

....and the finished system out of the car of course - after HPCing pipes and quick polish of the stainless muffler...

...and one last pic for anyone interested in the brackets and the cut-out to clear the crank pulley.

Nice work :agree:

OT: the underside of your car is way too beautifull ;)
Thanks for the pics.
Walter

Great to see different types of T4 exhaust. Here mine from Remmele. :)

Dasdubber,

That is one sweet system, I agree the under side of your beetle is far too clean... Have you used the exhaust yet?. if so what does it run like.

good to see another downunder type IV.

silver bullet,that Remmele is kind of funny looking, what does it go like, is it a race exhaust?. Do you have any more pics, maybe of it in the car.


Keep them coming...

AFAIK, it should be comparable to a Tangerine system, both in price and performance :D

Walter

Cheers Paul, the underside is still clean because the car is not yet running! Still in the midst of a full body off resto (the pic was still when it was in primer, now its finally in paint). It will get dirty soon enough - and I can't wait to hear what the exhaust will sound like, I will have to upload a sound file and post the link here when I get it running!

Hi Paul, its a race exhaust from Remmele. Wanted the BAS Race exhaust but they need certain no. before they start producing them,couldn't wait so.. Yes as Wally say comparable to Tangerine. :)

Tangerine, Remmele, Magnaflow, etc. -- Does anyone have pics of these on their car? (Their Web sites don't except for Tangerine and 914s.) I'm personally interested in 1302s and similar, but why not make this open season for all types of Types ...

Oasis...

Cheers for your post... yeah if anyone has pics of these systems lets see them.

However lets try and keep this thread to TYPE IV exhausts to fit any year beetle.

Many thanks Paul. :cool:
