EWT, I had my centre muffler removed, and the exhaust bloke said he thought he should have taken the rear out, but after driving it I was happy. It is louder when started up (lumpy, big cam V8 spec (not quite lol)), as it would be, but once it is warmed up it is fine. 80-120 bugger all noise, unless hard accelerating, which sounds a little louder than stock but waaay better hehe. Good bit of crackle too. As I said in my write up, around town don't drive in D, sounds silly, in P it is good, and manual mode it is great fun. In my opinion it could sound better, but it is $120 compared to at least $1000. So when you consider that it is great IMO. It is good to hear the revs now...
