That's good to hear D3fy.
Armed with the part number, I was able to get a price from Lexus Edgware Road for the TTE Silencer (again, the parts department hadn't even heard of the product!). I was given a price of £264.43 incl. VAT (£225.05 excl. VAT) and delivery could be within a couple of days.
Will I be able to get a Goldies member discount on this part?
Do parts prices vary from dealer to dealer?
It does seem odd to me that parts departments aren't even aware of these products. Surely aftermarket products like this could add substantial profits to Toyota's accounts so why don't they make staff/consumers more aware of them?
If I were head of Toyota, I'd give every customer a brochure of aftermarket mods for their cars!
