Patriot Exhaust H8059 1-5/8 Specific Fit Exhaust Header for Small Block Fits select: 1988-1999 CHEVROLET GMT-400, 1989-1999 CHEVROLET SUBURBAN

if the O2 sensor is on the passanger side then why would you not put the fitting on the pasanger side but insted i have to go buy wire to make it go on the other side why is this

I have purchased these for a 89 chevy k1500 4x4. they fit great for the most part easy install.BUT I purchase these not knowing that there is not a exhaust system kit that will easily work with these.. My initial plan was to use purple hornies Bolt-on turn down glass packs. but they fall right on a crossmember and would either have to cut them shorter and re-weld the turn downs or just buy another set that is shorter. Are initially wanted to purchase a set of hooker competition headers(They have a direct duel exhaust kit for these headers) But they were not in stock anywhere so I went with these. so now I’m just gonna have to find and exhaust kit and modify to to work with the headers
