I've got the VZ thunder 6 liter, Automatic Had exhaust bros do the cats back and put two pipes out the back with dual tips to look like the VE's. But I get a terrible drone noise in the cabin when the car is under load but not high revs. Any ideas how to make it get a good note but no drone noise??? Cheers
drone is the note at which the exhaust pipe resonates. only way to change the drone is to change the characteristics of the pipe, whether that be shortening/ lengthening the pipe, reducing or expanding pipe sizes etc. my guess is that it has no rear muffler? if thats the case, maybe add some hotdogs to the back, or a muffler.
Thanks. It has a little hot dog muffler on the back, I've received a quote to put a bigger muffler on the back but I think that might reduce the note of the car. I was hoping to keep a little bit of that V8 sound. Any ideas on how to get a great note but not the drone?
