Hi

Is there anyone who have expierniece in aftermarket exhausts like Invidia q300, hks silent hi-power or yonaka for accord 7 2.4 Automatic .
I have to buy something to kill the drone between 1200-1800rpms , but also would like to get good sporty sound if possible.
Did anyone install one if them and would like to Shere opinion about it ?

Thanks
 
Aftermarket exhaust are usually worse for drone than OEM. Download the Spectroid app and find the offending frequency that peaks between 1200-1800rpm. Probably around around 60hz.

If the exhaust has a name like 'Hi-Power' it is either going to be consrtucted lighter than OEM, and/or have better flow for similar weight. Either option is going to have shortcomings with the dB readout at certain frequencies

A couple of years ago neighbours complained via social media when somebody nearby was commuting for shift work at around 2am each morning with a full flow thing under his hatchback. A wet baguette up the pipe a fortnight later and everything went back to normal.
 
I did some research and looks like HKS silent high power has a special chamber near resonator that completely stop drone . The problem I have ,is that its difficult to hear the sound let's say on you tube. Watched many videos but on each one sound different ...
I know that automatic accord is more difficult with drone on aftermarket exhausts than manual.

I am not looking for something Loud to wake up neighbours in the morning , just want to get decent sound with no drone
 
To be honest , now I have this type of rusted and deattached resonating exhaust, even my neighbour with hearing problem told me he can hear it and its Loud like hell
 
Thank you for the message , that was the one on my list ,bu I am affraid it won't give me little bit more sporty sound ,it will be like OEM ...
Still thinking between this one and one custom made from Poland called Mar-Tec .
Have a look on this ,is Fujitsubo will sound like this or more flat ?
I have 200cells cat installed in mine ...
