Hi, it`s a 42mm AF clubman`seems to of got louder(used to bark like a dog now barks like a monster dog)Also there appears to be a tinny rattle sound like something is loose inside. Doesn`t seem to of lost much in the way of performance though.
Also if the pipe was knackered would this cause the engine to run lean?
Cheers ove.

GOD the thought of a clubman being louder is a frightening thought :o ..sounds like baffle has come away (common) get it split open and reweld baffle and weld back up..Not an expert but i would of thought if the baffles loose the gases flow would have changed so might well be running lean or rich...one of the bigger boys will answer that im sure..

Sounds like the baffel has broken off inside the exhaust....The baffel is spot welded to one half of the exhaust prior to both halves being seam welded together....not impossible to repair but would probably cost you more in labour than a new one costs.....
But if you decide to repair it..... When you take one of these apart you can usually Improve them quite abit over the original assembly and squeeze a little more power out of the engine at the same time.....so if it was mine it would be cut down its length just below the seam cutting across the back of the inlet cone and grinding the weld for the tail pipe keeping the tail pipe in one piece Then the bottom half of the exhaust can be removed replace all the padding then weld back down the steel metal gause that retains the padding, after knocking it firmly flat especially where it meets the inlet cone and weld it back down. I usually make a new smaller baffel and fit it about 3 inches further back, Before rewelding the two halves of the exhaust back together which seems to mak mine rev a little more, clean up the welded joint around the Inlet cone and remove any excess material for a smoother blend and then depending on the engine its going on adjust the internal length of the tail pipe to suit..... I know this is bit long winded, and a bit of a challenge..... But if your not going to use it then you it might as well have a go......anyone half decent with a mig welder should be able to do the welding...
