hey i just bought a used greddy sp2 in great condition and i was just wondering what bolts connect the midpipe to the catback and i cant find a diy for an exhaust ... pretty sure it would be straight forward but some instructions in hand would help.

 

There's a DIY in the DIY section for a mazdaspeed catback and the bolts you reuse. You will need a new exhaust gasket available at napa or similar for $3.

 

You might not have the bolts that connect the mufflers to the right end of the pipe below. They are nothing special, get get high quality SS nuts,bolts, washer.
The bolts for the left side of the pipe are reused from the OEM CAT. The gasket for the muffler to pipe connection is not a special part, you should be able to get one at any auto parts store. THIS thread might also be of interest.
