Re: 1970 GMC 1/2 Ton 350

First noteworthy mechanical upgrade in a long while. Replaced the rusted out 2.0" exhaust system. Installed 2.5" pipes, h-tube and Summit Racing 2-chamber "Race" Mufflers (Flowmaster 44 clones, 1/3 the price). Entire set-up ran me $266. Took me about 4 hours to remove the old exhaust and replace with the new. Very happy with the results.
