Everybody likes the whole big horsepower mods and stuff but I was always curious about tranny mods such as a lightened flywheel. Im sure that not a lot of 5th genners have invested in tranny mods so I was wondering how come. Is it not worth it or the money or what. I always thought that better power transition was great but I'm not to educated when it comes to the maxima trannies. Can anyone expand on this?

BTW, what is the stock diameter of our exhaust piping?
