i pretty much told you everything about it… let me know what you think and if you got any questions

i’m not sure what series flowmaster it is, but im guessing original 40 series. as of now, mods on my car are: ported and polished heads, intake manifold, and throtle body. scat crank, new pistons, high performance oil pump. 3.43 gears, stage 2 clutch, high performance shift kit, and a flowmaster exhaust
