Eh eh wait first porkyrock.. Some people with loud exhaust but they don't "preaggggggggggggggg" around on purpose to show off ma.. Especially when you are moving normal speed or just minding your business.aiyo....citrus found out my secret liao =P
I've noticed/seen many cars even with loud exhaust but they are quite respectful if you don't kacau them.. Whether it's fast, or slow car.
But your car's already a known ZTH ambassador, whether you loud or quiet also still gonna get attention lah wahahahahaahaha
