I can't find that particular part on its own. The lad I got the car off said that it currently has the WRC one and he gave me the above part saying this is the Sport Powervalve system incase the WRC is to loud.
I just want an indication of the value as its just sitting in my house doing nothing, thought someone could grab a bargain as it cost me nothing and could be beneficial to some that'll actually use it or make some money off it themselves.
Problem is I can't put a For Sale post up in the classified forum either
I think understand the situation now.
I bet the original purchaser bought the exhaust with the prestige (not sport looking at the current offerings) and found it too quiet. So as an extra, he had the WRC mid pipe fitted instead of the the spare part you have in order to release more noise.
I think the current price for the sport midpipe that has a single silencer and an extra welded on the side of the pipe as a dead end they call the dynamic drone eliminator is about £395.
So you could market your part to people who are finding the WRC section too loud for maybe £200 if it is in excellent condition.
