is it ok to use a glasspack muffler as a presilencer??

nope ... will blow out in no time ... even my borla blew ... here's my thread for a better solution:

no time to make one..need a cheap alternative!!

it will blow out really fast.
get a nice rb presilencer.

Yeah; rotary exhaust heat will burn a glasspack right up.
