I know there are a lot of people here from the LA area and was wondering where you all went to get your aftermarket parts(headers, exhaust, etc.) installed? I was also wondering if it is cheaper to order parts from websites and take them to the shop or have the shop order them for you?

For installation check out The M Shop www.theMshop.com. Contact them and talk to Joe.

Sometimes its better to have the shop order it for you because they can give you a discount on labor and/or ont he parts at the same time.
