I called JEGS they told me that part number 520-16823 is a 2.5' exhaust system.

What is the pn for the 3' exhaust system and where can I get it at?

 

Here's the part number for the systems me and my GF just ordered up for our cars. HOK-16822HKR

3" all the way back, same chrome tips, and same muffler for $215 from summit. It is specified for 82-84, and the only difference I can tell is the flange for the cat is an actual flange, and not a slip on. Not a big deal at all

 

Have you put the 16822 kit on yet?

Will you do it or a muffler shop?

 

Ourselves. Not on yet, waiting for better weather. Probably a month or so

 

How do you plan on mating the (slip on)cat to the hooker flange?

I am planning on buying a carsound cat maybe I should get one that is flanged.

 

cut off the flange and weld it.

If you can't weld, you could always use adapters and clamp it.

 

Thank you

 

just so u know all those hooker cat backs are 3 inch...the tail pipes are whats 2 1/2 inch....i went to holleys site and looked up it up...they are are 3 inch exhaust systems.....jegs musta got confused

 

Correct. The only difference is the reducer/adapter on the end of the I-pipe where it mates to the cat. My TBI specific cat back is 3" but had a 2.25 reducer on the end to mate with the stock cat.

If you are going with a 3" cat get the TPI specific cat-back. That way you don't have to cut off the reducer.
