I replaced my stock R/T 2/14" Exhaust with 3" Hellcat pipes from the Cats back. Sound is louder with more rumble. Wondering if the 3" pipes has lowered my boost so that I'll need a smaller pully for my Procharger?

Have you dynoed your R/T after installing the exhaust to see if you picked up or lost power? Do you have a boost gauge or able to log your boost to compare them?

Boost is actually a measurement of restriction and if you freed up the exhaust a bit, maybe that's the reason for your boost to drop. The best type of engine for boost is one that can make the most power on the least boost. It shows that the engine is efficient and can move the air and fuel easier.
