Dual Exhaust/ Compression and HP loss??

[dsmtuner1987]

im gonna side on the single exhaust on this one.
with what you have done it wouldnt "hurt" per se your performance, it would give you a little more top end HP. if you go with single exhaust, dont go any bigger than 2.25. its the turbo motors that need the more freer flowing exhaust cause on those cars an increase in flow can actually help the turbo boost more. a friend of mine put duals on his hondurrrrr with the 2 tips that point up and its one of the ugliest things ive ever seen.

about the "just put another muffler there just hanging, thats gonna look funny to all the other "real car guys" when they ask why one muffler is black in the tip and the other isnt..... (ive seen people using spraypaint to correct this, kinda sad)

i have nothing against duals myself, they just have to be done right (being an owner of a 4cyl car with duals)
