Does the hooker catback have a reducer on the 3 inch pipe? There are several models available which one does not have the reducer and will fit on a 3inch cat?

My friend installed one from Jegs on his 85 Z28 and it had a 3" to 2.5" reducer on it. I think it was the 82-85 305 kit.

Thanks for the info, I wonder if the 86-up does not have the reducer on it, does anyone that has purchased this know?

I got the one thats for the 86+ HO models, and it does NOT have the reducer on it, it's 3" all the way from cat to muffler.

Thank you for all your help

 

You want the one listed for 86-92 single cat 5.0/5.7 TPI cars. That model is 3" w/ no reducer. Have it on my 87Z, bolted up to the stock 3" cat and to the Catoco high flow 3 incher that I put on. 85s originally had some kind of different cat hookup though (maybe it was only on the y-pipe end, I don't know), I assume you aren't running the stock cat setup or something...

I got the proper model for my LG4 and it did have the reducer on it as it was supposed to. They basically have what you need whatever your application is. A word of caution: Although the hangers line up with the stock hangers, they aren't necessarily the same. I had to improvise to get the Hooker hanger to work with the car. Not difficult, but don't get cuaght with your pants down.

How does that hook up to the cat? Is it a slip fit or some other method? I'm also looking at the Hooker catback and plan on using no cat, so a slip fit adaptor will work best for me.
