70 mph speedo chime disable it . its behind the clocks in the dash

sounds like annoying speed alarm. If you take off the top of the dash cover there should be a small black box (I like those..lol) just disconnect that...

 

HTH

I believe the limiter is set at 112 mph

i've still got the cats and i think the 1.5" restrictors are still in the exhausts too. :headvswal

dunno if its limited not really been fast in it yet, as 112 is about 180 kph i think n not being near there yet will check it out (on privte race track of course), annoying chime at 70? why was it ever there in the first placE?

Have a look under the car and see whats there .... you may hear them purrring if your really careful ..

Japanese regulations I believe. Its a warning that they are breaking max speed limit.

 

Restrictors are effectively washers in the exhaust that restrict flow. They sit right after the cats. They can be "dremmeled" out, or a aftermarket Cat back exhaust fitted.

no dont wake them up!!!! every morning before you start the car put half a can of wiskers in each tail pipe that will encourage the cats to work more efficiently :tongue:

I am going to lay down my head is spinning .... look under the car though kenny, if you are not sure take a piccy and someone will tell you if its still got cats.

you cant really as you have to remove the pipe before the cats. there will be a washer approx 1.5" bore welded into the pipe. most people grind it out when decatting as it saves removing the pipes twice.

all the best
