Ken Brock sold those years ago.
You can get elbows and tube from Great Planes Aircraft 800.922.6507, and weld one up.

Or you can call these guys--Speacialy Products Designs-- 888.778.3312 and they can build you anything you want.

You are better off to make the pipes 44" long for best performance.

I agree with Jake. Great Planes is a current source for anything VW. His phone number is Steve Bennet 402 493-6507. He also sell an engine assemble manual for the type 1 VW for just $14.95. I hope this helps.

Jake, do the 44 inch pipes equate to the best torque for the powerband. I will probably use a 52 inch prop. I haven's tried to figure what prop tip speed this will equate to yet. I was hoping to turn the Revmaster 2100cc engine fast enough to develope the 70-80 HP advertised. Would a 4 into 1 system work better than 4 individual pipes? Thanks, Alan

Hi Michael

Could the "secret" of that 4 into 1 be that there is always one exhaust flow "drafting" the whole exhaust manifold system at all times, thus creating a better intake flow ???

Tony, yes, it's called scavenging, a known exhaust tuning principal. The pulse from one cylinder 'pulls' the exhaust from the next cylinder to fire, in a carefully designed collector.
Free horsepower, and torque. Primary tube length, and collector merge design and size
are critical. Study Jap superbike exhaust.
