manifold ?

[racobra]

the motor is still stock as 29000 miles on it just thinking about doing stuff do it .I was just wondering about the manifold .so on a stock motor its really not worth it then save the money for head work. the car has 3:55 gears cf dual fric clutch B&M ripper shifter ,subframe connectors, 4 point lower chassis brace, strut tower brace,hotchkis lower and upper control arms, slotted rotors front and back,1 5/8 headers stainless ceramic coated, bassani stainless high flow cats and borla exhaust, ram air set up
