gutted cats/cat delete
How do you guys do this? Take it to a shop to do it or do it yourself? Mine appears to be welded on, so I imagine I would have to cut it off and poke out the insides then re-weld it, or at least weld a pipe on in it's place...but a straight pipe won't pass the emissions inspection (CT). Any thoughts?

A shop can't do this for you. Very illegal! The only way to gut your cats is do it yourself. On an '84 the cat has plates at each end with 4 bolt holes. If yours is welded , it is not origional.

Re: gutted cats/cat delete (Justin1984)
What I am planning is to bite the bullet and have 2 exhaust systems. I will use my ported stock exhaust manifolds until I get the fever to install headers. So, my everyday system is gonna be straight true-dual pipe all the way back to the mufflers. My "emission" system is the all stock parts that I will swap in and out for the test(once every 2 years here).
BTW, a muffler shop might do the swapping if ya bring the car in/take out on a trailer. They probably will ask you if the car is registered for "off road" use. Maybe, if they "work with you" it can be done.

Go to my website ... go to projects, then gutting cats... :D
BTW, I don't know how the '84's exhaust is, but on mine one cat was really easy to gut, the other was pretty hard, and I think you should have one more cat than I do (pre cat)

I had my y pipes taken off with the two cats on it. I had new ones installed. All I know is that its blocked badly. So if anyone is interested in purchasing it for their own gutting pleasures then let me know.

Re: gutted cats/cat delete (Justin1984)
The 1984 Corvette may have had the least complicated exhaust system of all the C4's. After the manifolds, there is the front "Y" pipe connecting each of the manifolds to the single (only) converter with a 4 bolt flange. At the rear of the converter is the rear "Y" pipe, also bolted to the converter with a 4 hole flange. The mufflers attach to the the rear "Y" pipe with clamps. That's IT! The converter may be removed, by undoing the 8 bolts (4 at each end), gutted, and reinstalled. QED
