sled_mack 05-19-2006, 08:21 AM Depends where the truck was sold, I think? Mine does not have it, but I think CA trucks did. I'm sure someone can confirm. If you haven't done so yet, find the forum to post your VIN number. I think it will tell you what was original on the truck, and I know it will tell you all dealer performed work on it. Good stuff to know either way. Oh yeah, and welcome to the site!! bdas70chevy@cox.net 05-22-2006, 08:27 AM how would i find were to post my vin? I would like to check it out? Are you talking about car fax? thanx briano 05-22-2006, 08:51 AM scroll down on the main page to VIN Request. mad 05-22-2006, 08:53 AM In my opinion there is an easier way. Look up under the truck at the front pipe. I'm assuming that there is no cat there right now. Measure the pipe. If it's 3 1/2 inches across and NOT 4 inches or bigger then it's most likely a factory front pipe. That being said, also look at the muffler. If it is a stock, bigm hulking oval shaped muffler then it's factory too. Based on those observations I'd say it DID NOT come with a cat and is not from California because I don't think anyone replaces a factory exhaust with another factory exhaust. Only if there are aftermarket parts under there would I be suspicious/worry. Hope that helps. | ||
