    CGT exhaust questiion

    Does anyone know if the vacume hoses to the exhaust can be disconnected to give the full exhaust note at low RPM. I was told that the vacume lines hold the flapper valves closed and only open once they reach a certain RPM --giving the full sound of the exhaust

    Do you know if you just plug the vacume lines or do they need to be connected to eachother

     

    Thanks

    Since the vacuum motors are sealed systems, I would guess that plugging the lines would prevent them from actuating.  I'm not sure whether the vacuum applied by the ECU causes them to open the bypass or close it.

    An experiment should reveal the answer!

    Re: CGT exhaust question

    I am afraid the answer is no, although an experiment is definitely worth it.

    I've fitted mine with a Tubi straight pipes, the noise is intoxicating although possibly a bit too loud on long hauls.

    The OEM silencer is a massive box, and incredibly complicated inside,

    but the original sounds does indeed change around 4000 rpm I'd say to a muted F1 like high pitch noise, it's beautiful but like I said, muted and only at high revs, hence my choice for the straight pipes.

    Noise is insane, sounds literally like a LMP1 from Le Mans, which is what it was actually meant to be anyway.

    Good luck and keep us posted.
