Apexi (N1 I think) rear box & straight through centre section (unknown brand).
Centre has fittings to hook up to factory air pump system to help lower emissions, 75mm bore.
Rear is 75mm stepped up to 90mm bore with 4 1/2" Tail pipe. Both were on my car since I have had it. Good but used condition, centre has surface corrosion but seems solid with no holes.
Would prefer to sell as a matched set.
£200 ono, collection from Gloucester preferred on this, I don't really fancy posting it.
