which combo of headers and high flow cats give u the most torque and hp???

 

the consensus seems to agree that crawford's headers and cats provide the greatest gains.

problem was that the crawford cats seemed to be weak build quality.
however, the new revision of the cats seem to be holding up well.
i spoke to a mechanic that installed one of the new ones and he was impressed himself at the quality of the new ones.

fitment and quality are top notch.
this coming from the only mechanic i trust with my car.
said a lot.

as for headers, they're a bitch to install. even for the most qualified.

i personally have the DC and love them.

good luck and let us know what you go with.

 

thanx for the detailed info.
