Need Exhaust Recommendations

I took the Summit kit to four exhaust shops today. To install it and fab the two head/down pipes (because this kit is meant for headers and not exhaust manifolds) I received four quotes ranging from $250-$340. I knew it was not going to be a $100 install job but I didn't expect this either. Looks like the total for this project will be about $425-430. Granted it is less than the $500-$550 range for a custom-built exhaust but that did include MagnaFlows. I may have them installed on Thursday.
