I have a 91 vert with a catted h pipe going to two flowmasters. I have an off road h pipe that I took off my 91 GT that I am thinking about putting on my vert. Will the off road pipe make a considerable difference in the sound or will it be about the same. Thanks in advance

 

IM NOT SO SURE ABOUT THE H.. BUT I WOULD SWITCH THE FLOWS FOR A BORLA CATBACK.... YOU ALSO MIGHT WANNA LOOK INTO BUYING SOME HEADERS IF NOT ALREADY DONE SO..
