I took these off my donor car when i built my stang and have been running these on motor and nitrous. Now im running a turbo this year and was wondern if these were the straight through mufflers i need or if i should consider a new set of mufflers. They just say dynomax on them...no part number or anything else on them so i have no idea what kind or style these are...any ideas? Also, i have a 3 in. downpipe and im pretty set on having a y pipe made and split it off back to duals. Should i stay with a three inch exhaust or will 2 1/2 be sufficient...im only planning on running about 500 hp now (stock block) but in the future i may upgrade to somthing that pushes 6 or 700 hp...will this still be good...i just dont want to have to buy something twice.
thanks for any suggestions and i have a pic below of the muffler.
awesome im glad to hear! now i dont have to buy new muffs!! So dual 2 1/2's will be sufficient even if i push up wards of 600 hp in the future? Btw...do these mufflers ever wear out to where they need replace or repacked?
