Hi guys

I got my pre cat delete pipe fitted yesterday, sound good and it's a bit quicker, but my Clio has now developed a very loud knocking noise from behind the pedals.

This mainly happens during hard braking and sometimes when pulling away, The subframe had to be dropped yesterday so I assume it is it is something to do with the knocking noise.

My mate who is a mechanic is looking at it tomorrow afternoon, but does anyone have any suggestions as to what this might be so we have something to go bye.

Cheers Luke
