Installed mine today.
Can't say I feel any difference in vibrations. Maybe some slightly added noice in neutral, I'm not sure.
My main impression are that the engine is more connected to the gearbox, gaspedal and the wheels. Hard to explain but less slack in the driveline. But still, couldn't feel any slack without it, it's like a new dimension. Aha, it can be like this aswell.
Under heavy throttle the engine sounds much more aggressive. I've stock downpipe but the difference I can only imagine but like adding a downpipe to stock catback?
