i race a 95 GT at the local dirt track. when i bought the car, it had a resinator on the exhaust. that quickly came off with one jumb of the mud burm on the inside of the track. and a few burms later, the entire exhaust kinda came off (oops)! so now i need to put it all together for a new season and i am wondering if i should put it on again or not. i no a few people that say no, but i was also told yes, ill need a bit of back pressure... witch is the truth? any ideas???
