are twin pipes legal on a gemi and will they give me more power if i use two sets off standard pipes/mufflers/resonators with the stock manifold and eventually extractors they would be home made with one pipe from the manifold/extractors into a y joint through two pipes, one on each side |

no, and no
why bother???? twin might be legal but a permit will probaly be needed. two sets of standard mufflers etc will give a 0.00001 kw increase i suspect. Just get a good 2inch or 2 1/4 ` exhaust (doesnt have to be mandrel) with one good straight through muffler (redback are good and cheap), and maybe another small one if to loud. |

Assuming you keep an acceptable ground clearance, It would be legal as it should be under the allowable sound emmisions, but power increase would be minimal. Plus I imagaine twin 1.5" tailpipes wont look real flash, and we all know what a 3" dump looks like welded to a 1.5" pipe, especially when you can see where its been welded!
