General exhaust question
 

ok, this is to confirm my belief, a glass pack on an FB 12A is probably going to hurt performance more than help right? The FB im looking at has it.

depends on the size and design, but the trouble with them is not performance so much as reliability. they melt, explode or both, and do so VERY quickly.

....

ok

Skip the glasspack and buy a real presilencer from Racing Beat. Its worth the money as it will last very long and does a great job at helping tame the rotary exhaust noise.

im not buying a glass pack, its already on the car that im looking at.

all i can say is it's probably going to be loud.
