Ok, basically when i bought my williams 3 I swapped the std exhaust to a magnex cat back. I have kept the 2 std sections, but theyve been kept outside. A bit rusty on the edges, but nothing to worry about, no holes or anything - but if i shake the 2 sections I can hear bits of rust in the 'chambers' (dont know correct names). This is the same on the centre section and the backbox. Am I okay to pop them back on or shud i not. My bro insists driving the car might force any bits of rust out..
Ive shaken them from side and side etc, but the pieces wont fall out the end. Any tips? Or wud an exhaust fitter have a better clue. The sections themselves seem fine - no rust holes or anything
