a combination of a few things...

1 i have a custom flash by CaplinSpeed

2 my truck is OBD1

3 i only have one o2 sensor(and its stock...lol). it is placed at the front of the cat in its factory setup. since it is at the front of the cat it only senses raw exhaust o2 ratios. by placing the o2 sensor right after the exhaust is combined it is still sensing raw exhaust o2. there is not a "post cleanup" sensor so my truck never really new if the cat was doing its job anyway.

 

Yeah, you lucked out and got in the year before mandatory emissions testing (if they even do that in Alabama).

I got a '96 so they make me do the sniffer

 

nope...no emissions testing here. heck, theres no anything testing here...lol.

 

Yea they don't test here either. Supposed to but nobody even bothers. So My question now is since I have a 98 and have the 2 sensors how can I eliminate my cat without throwing a code. I've heard just unplug the aft sensor as well as put the aft sensor out of the flow. So any suggestions? I wanna ago straight pipe.

 

there was a time not long ago when they didnt test here in NY either..... now they even barcode the emissions inspection sticker and scan them at roadblocks to prevent people from using bootleg stickers...

 

that is freaking wrong...no bootleg stickers and no "test only" cats. wow

 

That must really stink. So I guess thats what all those bar codes are that I see on newer cars. huh glad they don't test here.

 

its amazing how different everything sounds now. i cant believe a hollow cat vs this ypipe would sound so different.

 

I bet it sounds sooooooo good.

 

definately different...a little louder too (not too happy about that)

ill get a clip of it shortly and post it.
