Ummm....I'm having some space issues trying to fit a 4.3 into a Sami frame. Anyone know if you can buy a kit or parts to build your own headers? It's the exhaust manifolds and exhaust pipes that are causing my headaches. Mudlug suggested dumping the exhaust outside the frame.
On a related note: does the O2 sensor need to read all cylinders' exhaust, or will it function properly reading just one bank?
