i am fully aware that i prob will get pulled over and defected one day altho i hope not . i avoid driving places that are likely to increase that happening ie glenelg and avoid the city as much as possiable our gets used 4 or 5 times a week and gen every weekend so it spends its time on the road . funny thing is i have a 4 inch exaust from the cat back and the rear muffler has a 6 inch arse on it but unless you really plant it is not too loud at all give it the boot tho and it really howls up in the rev range not sure of the brand of exaust as it was on the car when i got it
