Antbody know off the top of their head what size sockets I'll need to install the bbk cat delete pipes. I don't have many metric sockets/wrenches at home and will just bring the right ones home from work.

 

I just installed my o/r x pipe yesterday. To get the stock h pipe and cats out you need a 15mm socket with a swivel head and about 20" of extensions to get the one bolt on the passenger side from the engine compartment, and the others I used a 15mm ratcheting flexhead wrench

 

Thanks. I figured it was close to a 15mm. Will have to get a flexhead 15mm wrench.
