Fuel mileage in stop and go traffic in the city with these cars is horrible, even if its properly tuned. I'm lucky to get 400km (240 miles) out of a tank (=12 miles per US gallon) when doing my typical city commuting. On the track its even worse as you get into the boost a lot more frequently.

Out on the highway cruising I get double the mileage that I do around town.

The popping sounds are always there - with a stock muffler you can't hear them but with an aftermarket muffler with no baffling etc. you get to hear all of it

Never heard of a Kool Vue exhaust system - if you need a great system talk to Brian (RarlyL8), and if you want to go back to a stock muffler I might sell mine as I never expect to use it again.
