Do you mind posting the link to the Chinese supplier of the undertray please?

The undertray was just off ebay, there are loads on there.
Do you have an n52 then and not an n53? The gains on an n53 of over 50bhp are obviously quite significant.
I was actually really impressed at the factory air filter on the n53, would be surprised if there are any gains at all to be found there.
How do you find the BMW performance exhaust?
