Ok i have an 89 camaro rs which i bought with some glass packs on it. I know that the glass packs arent for performance and are just there for sound but i was wondering if i get some flowmasters i was wondering if it would sound the same or if they wouldnt be quite as loud....i deffinitly want the performance though!!!!

Pipe that goes from the cat to the muffler is bent or something and scrapes the ground .

 

it's straight thru. how could that be bad for performance. a flowmaster is worse for performance.

HERE is the flowmaster for our cars. exaust goes in the bottom left inlet and exits the bottom right and top right outlets (in the pic on thier site)

this pic is what a glasspack is

EDIT: sry i never really answered your ?...the flow will have a very diff sound. not as loud and will make a drone noise after 2k RPMs...but i don't like flowmaster so i'm not very neutral
