Default I know it'* been asked before...

Just to make absolutely sure, is this the muffler i need to fit? I finally decided on the flowmaster for mine. It'* an '87 with the single in, dual out (on one side) muffler. Is this the one i need to order?

Flowmaster 80 Series, it is designed for Camaro/Firebird applications but works for us as well. Your setup is going to be different after you get the flowmaster. It has an in/out on one side and an out on the other. So those dual pipes on the one side will be seperated and there will be one on each side. So you will need two new pipes fabricated for the outlets.

Heres a diagram to explain why:

Damn captain, that'* a nice diagram!

Just for a note, where "N.A." is, that'* the rear header.. not that tube.

Also, there are some single output flowmasters.. but it would be the same setup, minus one output. I believe the output on those looks something like this [this is a shitty diagram].
