Ok I am going to put all new exhuast on my 305 tbi and I want ot know if these parts will work on it. I am going with the edlebrock headers made for the 5.7 tpi so I get the 3" y pipe..the catco 3" cat and the hooker cat back...the hooker cat back has a modle that will bolt up to the 3" cat correct?? any info would help.. and also is the catco 3" cat 60$ or is it more? Thanks for the help.

 

ya that works. Since you are buying a new cat, maybe you can get a 3" cat with the older thridgen 4 bolt flange. That way you can get the older 3" hooker catback which is only $200 vs. $260 for the newer one.
