| cooper S downpipe
I have a 55 reg Cooper S and was told recently by BMW I need to replace the downpipe - at a cost of just over £900 ! appreciate any advice whether a) this price sounds right and/or b) any alternative downpipe vs BMW that could be recomended ?
For £900 was thinking of maybe replacing the whole exhaust system for more performance and welcome any system suggestions here plse ? |
