Hi all. I have a VX series II S that is Supercharged and 4 speed auto (think they all are yeah?)
The car is completely stock apart from a twin 2.5" catback with a V8 rear resonator that has twin tips.
Now I have only noticed this problem ever since installing the exhaust on the car, because now I can hear the engine and ding ding I now see why they say commodore autos sound droney.
Basically if I let my foot of the accelerator at any speed above 40-50kph, the revs on the dash bounce between 1000 and 1500 and I literally hear the exhaust bouncing a note as I roll along. This is very noticeable if I come down a hill in D or 3rd (either one) and let my foot off doing say 65-80 it just proceeds to sound as if I am constantly touching the pedal like I want attention and it is driving me nuts!
Is this some kind of pressure build up that is normal, but only notice it now due to the exhaust?
Or a problem with the exhaust? Like, I am desperately trying to find a standard replacement online but it doesn't give me much to work with. Ps, I was dumb and threw the standard system out 6 months ago :[
