buy JASMA approved muffler... eventhough it will cost a bomb... but u wont regret with the money u have paid.... hehe.... Of course lar, we dont talk about turbo car loh... no matter what exhaust is being used, we'll still categorize it as noisy but nice.. haha... even stock evo exhaust also noisy but nice to listen...
coltrain, i guess because if the flow is too fast, making the engine cannot keep to the boost level... turbo kaki, is this correct?? Which a'pexi muffler u using, N1, Super Dunk Megaphone, WS, GT series n etc??
cheers
