they will last awhile and you want to lose backpressure. Backpressure is not good you want to keep the gas moving (high gas velocity) to promote scavenging. That is why a pipe dia can be too big for a given setup. Air and gas move slower threu a larger pipe creating poor scavenging

ok well i picked up 2 glass packs 1 per outlet i got a 97 v8 but i i hadnt realize how truely long they where til i went home and saw that i dont have room for the ones i bought i got cherry bomb 2" louvered there the 26" ones and they stick out a good 3 inches so ima go back and see if they have some around 20" so i can through on a nice pair of chrome tips.

back to back pressure though. ive heard you want to keep back pressure and ive had some experience because it keeps torque? and i really dont want to loose all the torque i have i dont mind some but not all of it. not to mention isnt it better for the engine to have some back pressure

velocity helps torque by helping ehaust scavenging (as in creating a vaccum)
