how i the stock SS exhaust? i know its better than the stock z28 but how much? and how does it compare to aftermarket or a cutout?

 

The stock SS catback flows well. The muffler in the catback is a little more restrictive than aftermarket catback mufflers. If you are looking for just power get a cutout. Otherwise most people just change the catback for a different sound.

 

if you plan to ever open up the motor or get an ory just keep the stock cat back and go cutout

 

The stock SS exhaust is pretty good. Don't change it, it is not worth the $. Like Kieth said, get a cut out.

 

cool, thanks guys, i think i'll get a quick time electric cutout and wire it to my fog light switch. keep the dash kinda factory looking.

 

I have a stock Z28 and bought a stock SS GM muffler for $40 bucks to change it out with. With an SS, you could get the factory GM SS muffler or if the car was ordered with the performance exhaust, you get a SLP custom muffler.

I do know that the GM stock Z28 muffler is 27 inches long and the GM stock SS muffler is 22 inches long. I dont know yet about the difference in the internal structure. I do know the SLP performance muffler is different internally from both the stock GM Z28 and SS mufflers.
