Do you mind getting your hands dirty?
Measure the pipe up and get a piece with a pair of clamps. I made a side exit from the manifold back for about £20-£30 including a 45 degree bend all stainless from Burton Power. A couple of clamps and some exhaust sealant if it doesnt seal and your laughing.www.burtonpower.co.uk.
2.5" x 0.5 metre stainless steel with VAT = £13.95. You can buy clamps for about £1.50 in most motor factors.
