Exhaust Bangs
Hi all.
I recently blanked off the dump valve on my car. It's a 98 GT wagon. wanted to know how the flutter sounds like. Put the car in gear to give it some revs, fluttered fine but then i noticed that it started to bang and pop. Then i tried it in neutral, and it did nothing. The real question is that why does the exhaust pops and bang in gear and not in neutral. And only when the dump valve is blanked off. Only mod the car has that I'm aware of is the PPP . Hope that made any sense.
Thanks.
