914 "F" pipes on a Bug, would it work?

[yetibone]

I had a brainstorm a minute ago. Late model US spec 914 2 litre's have the F shaped head pipes that come out of the heads, and go foreward to the heat exchangers. They have triangular shaped flanges with three bolts that attach to the heat exchangers.

Could those be used in a Bug conversion with two stinger megaphones bolted to those flanges, and exiting out from under the car? Picturing it in my head, I believe the stingers would come out to about the rear bumper, and a few inches outside the cutouts for the peashooter pipes on a stock apron.

Has anybody tried this with any succsess? If so, are there any pix of this setup?

Been there- done that...

If you don't have a 4-1 collector, or a 4-2-1 collector you are literally pissin in the wind.

The firing order and scavenge require it. When I did this I could not get the engie to tune, it made no power and it ran hot as hell.
With a TIV, exhaust is everything. I have seen 5,000.00 engines with 200,00 exhaiust not make as much power and run hotter than a 200 dollar engine with a 2,000.00 header- literally.

Due to the exhaiust ports of a TIV head, they are mucho sensitive to backpressures, scavenge, and volume. As the camshaft duration on the exhaust side changes this increases.

I understand that it would be a retrograde in performance from the headers currently on the market, especially if done as I described earlier (true duals, no union between the two). I just thought that would look cool , but It's an idea I'd thought of to lower the cost of a Type IV conversion for folks going with a relatively stock powerplant.

Could it be a basis for an exhaust system for a stock-ish Type IV? Mostly for those who don't want to dump $500 into an Ahnendorp header, $2k into a Tangerine, or can't find 411/412 exchangers to shorten? If the two head pipes were plumbed into a 2 inlet transverse muffler behind the apron would it be adequate for a sub-100hp Type IV, and have good enough ground clearance?

www.laperformance.co.uk sells exhaust similar to what you are describing.

Like I said, if its not merged, with correct primaries its wasted time.. Even on a 100% bone stock engine....

The A1 exhaust will be much more affordable than anything so far, and may even allow heater boxes of some sort..

Exhaust stuff is more rocket science than cooling systems and the most important part that can be bolted on to an engine- no doubt.

Ok, thanks.
