New exhaust

[treas92]

I recently bought a 2.25" cat back but haven't fitted it yet. I have the 2.4L Mivec. What can I expect noise and fuel economy wise?

fuel economy i doubt would change any if at all
sound depends on the muffler really / mainly

depends on size, type of metal, how many bends, how sharp bends, how thick the pipe wall is, what resonators are in it and what they are made out of, and the muffler and what its comprised of

basically, as far as noise, we cant tell u unless u tell us what material and does it have reso, and hwo big muffler and material

mil-steel : normal sports exhaust sound, pending muffler size it can be a deep or highish growl
stainless: slightly raspy and rattly sound

fuel will change becuse as most poeple do when they get it they become a bit more lead footed, so they can hear their exhaust all the time.
performance... basically nothing maybe 1-2kw and probably not even that

this whole answer has been said plenty before, try using the search function, or even google as its a question asked all the time

basically, as far as noise, we cant tell u unless u tell us what material and does it have reso, and hwo big muffler and material even if we knew this stuff its hard to tell what it sounds like as every car ends up sounding a bit different.
