There are some duals that have gains, but overall, more singles do make more power than duals.

Yes true, Dyno from the company / distributor. i should have specified, someone who has done some private testing and research besides the company producing it or the ones selling it.

Dyno's are so easily manipulated by people trying to market theyre products.

I geuss its just the battle of singles versus duals, i didnt mean to

I have seen several threads of private testing with stock ecu w/ stock exhaust, compared to stock ecu w/ aftermarket single compared to aftermarket dual, aftermarket ecu w/ stock exhaust, and aftermarket ecu w/ aftermarket single and aftermarket dual, and i remember seeing more in both tq in hp from the. Let me see if i can dig up the thread... so many bookmarks tho >.<


As far as the two exhausts you did compare about the single making less, that is ofcourse possible, but not for the exhaust systems over the board.
