Y pipe

I did not say it's a true dual when you have a Y-pipe...I said past the Y-pipe the exhaust is dual. And yes, the OEM Y-pipe is horrifically restrictive.

You still call it a dual even if both pipes go to the same muffler??

Really, if you have two banks, they have two exhaust paths. Even if they merge somewhere, it's technically a dual exhaust.

If you think about it, the two exhaust manifolds are what really matter. Everything after that is a compromise between a whole host of factors aimed at where the motor will be able to best take advantage of the piping diameter, scavaging, noise modulation, and emissions.

Even the so called "true duals" usually have some sort of a connector pipe between the two paths, and on the single muffler, dual outlet, you still have two paths; it only joins at the Y for purposes of scavaging and noise modulation.

If you have a motor with one bank that splits into two paths is that more of a "true dual"? Does it matter?

ebay test pipes will make just as much power as any other (Art pipes may make a little more) -- BUT, if the rasp will bother you, get a set of resonated ones.
