hey guys, im thinking about ordering l/t headers and an o/r h pipe for my 85 gt with magnaflow catback. what have you guys been seeing as far as power increases with this over the stock
2-1-2 exhaust.

also, does anyone know if 85 gt's came with an 7.5 or 8.8 rear, i dont have a tag on the rear i checked, i want to get some3.55s in with the exhaustbefore i go to the strip

Dont waste time with bolt ons. You want power? Crack open the engine and go from there. Get exhaust because of the way it sounds, not for the power it frees up (as your objective).

im putting a 347 in this winter that im building right now, im just looking for some minor power adders for now until i put the engine in.
