Pack them up and send e'm back and take the financial hit and put it down to experience,I've no idea how old you are or how long you have been biking but if this is your first taste of such it most certainly won't be your last at some time or other we have all been there I keep things hanging on the garage wall just to remind me that all that glitters ain't gold.

On a more basic outlook you buy pipes and exhaust's from people who make them not from folk who sell e'm and why I always treat Wunderlich with great suspicion because they don't actually make anything either.
