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?
