  1. Earth Shattering 5 Star Review

    Posted by on 31st Mar 2017

    Earth (and ear) shattering sound! Absolutely lovely. I decat pretty much every car I buy (even the wife's), so my McLaren was not going to be any exception. Super deep and throaty tone. Very happy with the build quality and fitment. 10/10
