Mate,
Its best to stick to 2.25 inch pipe, a big centre resonator (should be bigger than original) and a good rear muffler (devil, remus)
The best bet with custom systems would be to go for a slightly larger dimension than the original system. In this way, the back pressure can be reduced and you can get a bit more power and torque with this setup.
What you guys think about this?
it´s a sensate choice, Max...2.25 pipe is the original size of my ZX, I take the 2.5 because a friend was selling to me ^^
the noise of the exhaust is exciting at this moment, but one hour I think it will be boring. in this case I will change the rear muffler to the an original one of the another car with big engine...
and here are the graphics
the original:
exhaust + conic air filter:
comparative:
the original setup was: low octane gasoline, dirty and old air filter with the original air box, original exhaust...
the exhaust + conic air filter setup is: exhaust and conic air filter
(full 2.5 inches exhaust with 03 high flow mufflers), reconditioned head (the head gasket was changed because overheating
), high octane gasoline...
humm...and that´s it
