I have an 88 V6 4runner with downy headers on it. have fun getting the cross over pipe out

Truck runs much better with the headers but hooking up the smog isn't much fun. I ended up using 1/2" copper pipe and fittings from the header to the smog crap on the passenger side engine bank (house plumbing stuff) and soldered it together.
I get better MPG and it runs a little cooler
