i just bought a 92 rs. i got a flowmaster exhaust on it and i was looking into putting a y-pipe on it. what i want to know is how much horsepower it will add also wut will it sound like (rumble,loud,ect.). and how hard is it to put on yourself and if anyone wants to leave broad directions on how to do it. thanks guys

 

The car comes with a Y pipe. If you want to put in a better one you may pick up around 5HP, and it will do nothing for the sound.

 

A new Y-pipe is usually installed with headers, a new Y-pipe with the stock cast iron manifold will do nothing for you.
