Thanks Mate, Peter from Carline Perth is fitting it tomorrow. So kinda worried and not sure what to Expect. I am told the STD Dump is 3inch so why would he change that and the cat. I really not goign to Mod my car to much as I have extended Warranty but from wehat I been reading on here its not worth the paper written on. touch wood my baby has not given me one ounce of trouble from Day one. I don't race Drags I race Speedway on the other side, sometimes we have Practise with the Drags on Wed Night. I run a Speedcar (Midget).
