Exhaust mods on '03 M45

[4 speed]

Has anyone had any success with exhaust modification to an 03-04 M45? Mine is so quiet you can't hear it run. I would like to get some mild sound but do not want to affect my warranty. Any info would be appreciated. Also, info on a chip & cold air intake would be welcomed.Thanks4 speed

"Chips" are generally only done on forced induction engines due to the fact that they can re-map the fuel curves and such to be more beneficial to an updated turbo/pulley or to even small amount to the stock unit. You will not find anything out there for this car. I see you have done some digging and dug up some older threads so you have probably already came across more than a few threads like this already. Sorry for the dissapointment it may cause but you will need to go custom on all your performance needs.Cheers and best of luck!

Exhaust would have to be made by an exaust specialist...becuae there are none...someone on this forum had a specially made exhaust..so it can be done for the right price...no CAI or chip...there is a Stroker kit in Japan for alot..but nothing here....JAPAN is where it is at...for the right price anything can be had...but if we were spending that much i dont think we wouldn't be driving a 03 M45 unless we were in love with it. We would be driving an 07 and modding it....It is not a civic just cause the used price was low dont mean the parts are
