In answer to some previous questions,
Yes, i agree through the side panel, not over it, looks the best.
They won't be £99, probably around £300 for the manifold/collector sections and about £120 for the silencer, as a rough guide.
Sensor point would not be a problem.
Les, not a chance, I'm on holiday as of Saturday till the end of the month
Nick, yes, they'll do one in a day or less depanding on how complicated, so you'll pay labour and the cost of the item. You just need to get your car up to them.
Kind regards
John
