I want to buy some headers and a high flow cat for my 85 305 carb, the thing is im not sure what headers will give me a great sound while boosting horsepower and retaining A.I.R and all other emmisions equipment. I have a flowmaster 80 series muffler on my car with everything else stock. I was thinking of SLP headers but any help from you guys would be great and what are you running, lemme kno guys....

 

SLP is among the best, but for the price if you're just looking for some more HP Edelbrock or Hooker wouldn't be bad, though I'm not sure if Hooker has AIR.
