yeah - lots of time
- there are a lot of very smart people out there that think about this kind of stuff every day...
just for your info - some engine builders have tried a slightly different configuration of linking the primary pipes: instead of linking 1&3, 2&4 the linked 1&2 3&4. the theory was, that at high RPM the amount of exhaust produced would be sufficient to create a pulse to pull gases from the next cylinder (wich would require a very long pulse).
what they found was that they needed incredibly short primaries to actually get a scavenging effect, ruining the torque spread. it did actually allow the engine to rev a little more freely at very high rpm, with a 1BHP gain at ~10000 rpm when compared to a conventional exhaust design.
needless to say - the idea was binned very quickly because it made the car uncompetetive. a 1bhp gain did not justify the lack of power everywhere else... bearing in mind that these are top spec engines - imagine what an exhaust like that would to to a "mildly tuned" engine.
no speakers... no bodykits... no bullshit!
