I had a sportex 3" jobbie on my cinq and it was nothing but trouble!!!,it sat right and looked sound,but the weight in the box was too much so when i flung the car about a wee bit it was moving and jumping about all over,and in the end a speedbump wiped it out!,so i had to weld it on,so i had one big pipe from front to back!
sportex do come with a bracket to fit to original mount,but its the weight that causes problems,would have been better to make another mount from the other side too
i would defo recommend the look,but wouldnt recommend getting it done!
and before you all have your say it was fitted perfectly,was all sound,it was just a pain in the centre rear!!!
p.s got mine from evolution sports in peterlee(north east) £87!
Bargain!
