we are thinking of istalling toyomoto tubular headers but need you guys expertise on this matter. we heard that:

you will get a substantial increase in hp? ( 17 to the
wheels )

the car will sound super loud, like your hondas. ( we running
tanabe's gold medallion )

you will have problems with your engine check light
etc.

any other problems and/or remedies.

thanks you members for your anticipated help.
