I have yet to order my headers but can get to fit my application. Would tri y`s be easier for fitment ? (425 into 86 rwd cadi )
Are they as efficient as full length headers? I do want reasonable scavenging ability.

Give Smitty a call. He's the one to go with.

i went on his web site and it says he sells kooks that are no longer being made

 

I think he may have bought some fixtures but now he manufactures them in house from the best materials and has also solved some of the earlier fitment problems that the Kooks headers had. Here's a thread from ROP about his headers in a Trans Am. His website may not be updated. You really should call him. He's a great person to deal with.

67 TX. Talking to a local fabricator over the weekend who seems to think 4 to 2 to 1 helps scavenge ,is easier to fit BUT labour intensive to make .
May go that way because I don`t want too much hassle in fitting a set of headers .
