when i bought mine it had just had a brand new reno zorst fitted.
about 2 months later the cat started rattlin so i fitted a de-cat...
bout 2 months after that the innards of the first silencer had been blown out n the car sounded and went sh*te lol
hence the powerflow s/s zorst thats on now, s/s so no worries bout ever havin to replace it, and its bent to the exact same shape as oe one.........with same bore pipe too.....so can this be classed as a modification???????????
