I have a 93 4x4 S10 blazer. Right now it has just a factory pipes, cat and muffler. I was thinking about putting some headers on it, and running duels. I realize I'll have to have 2 cats, and 2 mufflers. Which is where i am kinda lacking info on. I am deaf, but was a late in life thing, and I know the sound I want. The sound I want is a low, DEEP and mellow sound. I have a 4.3l "W" series motor.

Ideas?

 

Do you have the 2.8L or 4.3L V6? I am assuming its a 4.3TBI. Either way, you dont want to run true duals on these motors, they need some backpressure. If I were you and had benjis, I would go with anice set of headers, no cat (since you are emissions exempt), and a nice Magnaflow muffler with 2.5 or 3" mandrel pipe. And then put the rest of the money into a nice cam and tuneup.

P.S. search button is your best friend. Hundreds of posts on exhaust, etc.

Good Luck.

 

How is he emissions exempt???

Anyway, I would go with a set of headers, high flow cat, the muffler of your choice, and probably 2-1/2" pipeing from the y-pipe back through the cat and muffler to the tail pipe.

 

Dunno about up there, but in NC vehicles more than 10 years old are emissions exempt.

 

It's the 4.3l and fuel injected, has no "carb", is a vortec

WOW, I thought federal laws said any car from the factory the came with cats are required to have one. I'll have to check into that on a local level here in Oklahoma

Thanks for your input, so I take it that magnaflow is the muffler of choice these days? Back when I was younger and had my chevelle SS, we all run Thursh, or Cherry Bombs

actually, around here, it seems like flowmaster 40 is the muffler of choice. i have a magnaflow and i love it.

 

While a vehicle may be emissions exempt, that still doesn't mean that running with out a catalytic converter on a vehicle originally equiped with one is any less illegal, it just means that you 'may' not get caught. But believe me, a lot more shops are checking for the presense of a catalytic converter as part of the safety inspection process and many people are getting caught by it.

Federal laws supercede all state and local laws.

 

You could always nock the guts out of the cat and put it back on. i did it on most all vehicles i own. no questions asked when they put it on the lift. It all looks factory, most shops i go to here in NC dont even put it on a lift if its over 10 years old though!
