I have a 1987 k5 blazer tbi and I need a exhaust system. Does anyone know where I can get headers and a full exhaust system without cats for my k5 I have looked around on the Internet and can't find anywhere thanks.
 
You will still need the O2 sensor.

Why? Is the stock stuff broken? If not, just cut out the cat, throw a test pipe in place, and leave the rest alone.

For some reason the guy before me cut the exhaust off so I need to put a new exhaust system on an the manifold still has the O2 I wanted to run true duals with 45 deg pipes behind the rear tires or straight pipes
 
Duals are...pointless, to put it nicely.

If you have to have the dual look, run a single in/dual out muffler. But it just adds garbage under the truck.

Single 3" from merged headers will be more than adequate for the truck.
 
Can't you just go to a local exhaust shop and have them bend something up for you?

Hooker/Flowtech make a dual kit and it's pretty inexpensive. If you go with with headers, odds are you'll have to make some minor modifications to get everything to fit right.

I'm running Hooker competition headers and their split side dual exhaust on my 85. It installed pretty easily, I did have to change out the motor mounts to get the collector to clear the front propshaft, because my right side mount was basically broken. True duals aren't necessary unless you're working with big power, but since the exhaust on there was crap and the price was right, why not?

A good local shop can bend you up a custom system and install it for a few hundred, and you know it will fit right. Plenty of options depending on which way you want to go.
 
I'm over 5000ft has a strong stock 350 in my 75 K5 latter plans will involve a set of nice of headers and run them duel for better breathing up here. If your driving up lots of hills or live in the mountains or pulling boats and toys better breathing helps how ever you make that app happen
