yeh i would. they come with a lifetime guarantee and its stainless. they ask you to go back annually so they can check over what they have done and if the rubbers have perished or anything, they will change them. and you dont have to go back to the same garage, it can be anywhere in the UK that does the powerflow backboxes. plus you put hand over you lifetime guarantee to the next person that buys your car. so you cant complain!
like i said bud, you choose the noise, they will make it. and you can choose from tailpipes like subtle ones like mine, or literally things that you could literally put a your neighbours jack russell right up...
