Hello all, I have a 1997 silverado with the 350 and the goofy catalytic converter/down pipe exhaust setup. What I'm wondering is if they sell a down pipe piece that goes from the header to the y pipe without the catalytic converters. Any help would be appreciated.

 

and one needed for a 2002 Silverado 1500 w/ 5.3L

 

just cut the cats out and replace it with a piece of pipe...for Morris if you take the cats out you'll either have to buy o2 sensor simulators or get a tune to shut off the back sensors

 

1st problem is finding the simulators to fit a 2002 Silverado

2nd problem is what they cost

soooooooooo, I am thinking of trying this..... plug the sensors back into the harness and just tape up the thing to protect it and wire tie it to the frame. read somewhere that may just work...???

If anybody has a good link for ?mil eliminators? or ?o2 simulators? or ?oxygen simulators?.... please advise with link info

Thanks....
