throw down some combo's from the headors to the tips so i will have a good idea of cost and performance
i wudnt fool with headers , thats a waste ......... get the shop to cut the stock muffler off throw a si/do 44 on it and do turn downs
flowmasters make the mod motors sound like there underwater.... lmao but on the older motors they sound pretty good because the compression those old motors have. Headers you will gain about 20hp and 25trq. Its dynoed proven and also this is the dyno on our mod motors. so i can only imagine what kind of gains bats will have with a set of long tube headers
