[MYOBYDAVE]

WHAT IS THE STOCK EXHAUST SIZE ON A 1987 CUTLASS SALON WITH A 307
JUST GOT MY CAR A LITTLE WHILE AGO AND DOUBLE HUMP CROSSMEMBER WONT FIT
BECAUSE OF THE SHITTY JOB PREVIOUS OWNER DID
WANT TO DO DUAL EXHAUST OVER AND ALL I SEE IS 2.5" EXHAUST FROM SUMMIT AND JEGS
FLOWMASTER TOLD ME THAT 2.5" WAS TO BIG FOR STOCK 307 WILL LOSE POWER
WAS JUST WONDERING WHAT THE CAR ORIGINALY CAME WITH

Look on AZ or Advance websites. The stock size is 2.25...I doubt 2.5 would make that much difference....Pypesperformance.com has the whole set up from manifold to tips.
