I think that the flexi repair section only cost about £35 delivered. After giving this site a good examination - ie checking exactly where to do the measuring - O/D diameter of the exhaust after the flexi to get your referance diameter, measure the length of the flexi part only as indicated on the diagrams for the repair section, measure the overall diameter of the flexi - just for your own peace of mine (that was what I had not done to mine - so I had no real referance points to bargain with my fixer when he fitted the wrong sized part first time round!) - oh and remember to select the "top" grade one as I mentioned in the previous reply. Email them and ask for a quote to supply including p&p, they will reply quite quickly, send a cheque - and your flexi drop through your letter post (size permitting!!) in a padded bag. I quickly descided to fix my wife's Polo 9N 2002MY front section after VW told me that it was £350+vat (I think). Search the internet for a proper exhaust manufacturer - ie someone that can fabricate exhausts as they will have all the kit to do aproper job, by you supplying the correct high grade repair section, you will avoid the possibility of getting duff job first time round. The beauty of Senioraftermarket seems to be that you actually manufacture all sizes - so you don't end up compromising on the repair by getting just something that might sort of fit - in my case I ended up with an exhaust that was sealed, by boomed at certain rev ranges AND rattled off the crossmember - all due to a poor choice by the fixer first time round. I think that fitting cost about £60 second time (£95 first time when he supplied the repair section). Partco etc can supply general purpose flexi lengths but they are more suited to trucks etc when its only sealing the exhaust that is important - you don't want to end up with booming and/or rattling. It was someone on
www.briskoda.net that put me onto this supplier.
To be honest, I'd leave the exhaust as is - maybe try to wrap some heat activated exhaust badage round it (wet it first) - ie from Halfords, Holts, and secure that using these nice SS tie wraps that Screwfix sell - I did that to avoid hot exhaust spraying out against things that might not like it - but it was not very successful - but better than nothing short term. If your exhaust set up is similar to the Polo9N/Ibiza6L there should not be any chance of the exhaust section falling down as it is quite well supported. If you are getting an expert to do the welding I'd leave them to descide where exactly to cut as you can't really work out when its dropped and chopped exactly what alignment is required for the sorted section to fit back on correctly. They will work out where to chop it, remove it > chop it > refit it and add in the repair section > tack it on > remove section > weld up > refit.
