Which cat

Car is an 85 z28. Just picked up a hooker 16823hkr exhaust. Have heddmen headers and y-pipe so 2.5" outlet. Prefer direct fit without air tubes but can't find any 3". Or would the air tube matter? Looked at catco 9118 and wlk 15622. Any ideas? Thanks.....Zapr.

Re: Which cat

I have had that Catco cto-9118 on my SLP system for the last 13 yrs. What is the problem with the air tube??? If not needed block it off.
