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.

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.

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.

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 !!!!.

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.

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:

Thumbs up

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.

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...

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

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

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
