How much quieter do the aftermarket exhaust really go after you fit the removable bung in the tail pipe. I fancy going large but would like the quiet option every now and again!!??
They make a huge difference, obviuosly it depends on how LOUD your exhaust is, but on most they tone it down to around 'normal modified' exhaust noise levels.
