LC6529 Posted February 25, 2010 Share Posted February 25, 2010 Just a quick question to the mechanically savvy out there. Exactly what does the ECT switch do on the SC430? I have figured out that if you switch it to PWR the car seems to have better pickup which is pretty nice while on the highway. The gas mileage seems to suffer a bit though.. Just exactly what does the switch do? Also, where in the world can I find 3rd party exhaust for the SC430? I love the car but am so jealous at the Camaro's that have a big rumbling sound from their exhaust.... Quote Link to comment Share on other sites More sharing options...
aquanuke Posted February 27, 2010 Share Posted February 27, 2010 All it really does is hold the gears longer before changing, although I suspect theres more black magic going on. All the aftermarket exhausts dont really add much V8 rumble really due to the fast they keep the rear silencer. All you really need to do is take out the rear box. I had custom stainless exhaust made up locally and the rear box taken out. I should think any exhaust shop can do a similiar job. Quote Link to comment Share on other sites More sharing options...
