My plan of attack is doing a full edelbrock exhaust headers and rpm muffler set up. My question is should I get a HI-flow cat or just take the whole thing out?
Would I get more power if i just took it all out ?
Will it effect my pcm obd1 ?

 

In my area thay have no emissions testing

 

Must be nice

 

No emissions in yoru area? Sounds like you answered your own question...

 

Junk it

Also, read this Might give you some more ideas for your exhaust.

 

No emissions! Screw the Edelbrock stuff, they most youll gain from both is 23rwhp, its very pathetic. Get some longtubes and a highflowing exhaust. You'll see better gains than from those tiny edelbrocks. Horsepower TV did a show with adding all edelbrock exhaust stuff and they came up with 23rwhp or less. Most good catbacks get you 10-15 rwhp and that leaves the headers gaining like 10rwhp. Forget that and gain over 23 rwhp from longtubes alone!

get a high flow
i'm not some kind of environmental tree hugging person, but it's the least you can do
it's notgonna hold you back but 1hp if that

 

If not for the sound and power alone, don't get hi-flows because of the price.

 

I was charged $245 for a Magnaflow polished hi-flow. No emmisions = NO CAT

 

I vote no cat. Use the $200 or so dollars on other mods and spend a few bucks to put a straight-pipe where the cat is.
