It is 8Kg heavier overall, 4 Kg per side. My car, number 799, has alloy backing plates on the inside, not sure if the earlier ones did. I put some extra 40mm diameter load spreading washers on the inside as well. There are rubber gaskets fitted between the new brackets and the skin and larger anti vibe rubber bobbins than originally fitted. All in all, a better installation than the original exhausts. Ideal would have been to mount them to the chassis not the skin.
Thanks for clarifying me on the weight, that splits my concerns in half
mine is Sep.13 No. 877 I will check for backing plates in mine. do the new exhausts come with better bobbins?
