Exhaust
 

In my ever relentlessnes of touching my vehicles I am gonna upgrade my exhaust on the Expy. Being cheap (broke) I am going to use a take off OBS stock exhaust. I figure since its a straight through muffler and 3.5 inch it should let it breath pretty good and not be too loud.

When you look under there you'll see a "Y" pipe(after the headers w/cats on it). The next piece back is called the intermediate pipe(just before muffler). Do not exceed 3" on the intermediate pipe for it may cause a loss in low end torque.
Hopefully the hangers all line up.
FYI

On this one the next piece back is the one with the muffler on it. I am sure I am going to have to modify it to make it work.

Try to leve that piece attached to the muffler at 3" for as long as possible.
