Catalytic Converter Delete on LSJ

[XxChristalSSxX]

Anyone here done this? Is the oxygen sensor located in front of or behind the cat? Will it throw a CEL? Does it make it noticeably louder or just a tiny bit? I don't care about the HP gains; AL has no emission laws and I've always hated catalytic converters... one less thing to have to clean out yearly.

There is an upstream sensor and usually a downstream sensor. You would have to delete the rear o2 sensor or you will get a code.

Hm... Summit sells a sensor plug. Would that work?

 

[06CobaltLT]

That would work to plug the sensor hole but you would need to have the rear o2s tuned out so the computer won't even know they are there. Or you'll get a SES light saying they are not working etc.

Damnit...

that plug just plugs the bung so more exhaust doesnt escape. only way to not toss a CEL is to delete the sensor via tunning.

id recommend not going catless on a LSJ. sounds like shit

 

[XxChristalSSxX]

Double damnit.

So I guess my only option now is to buy a catless downpipe, right? & of course a flippin' tune...

 

[Projekt]

high flow cat downpipe is your option

 

[XxChristalSSxX]

Dang... I guess I'll be waiting for this mod then.

christal lemme know if you need a downpipe do offer a dp with a magnaflow highflow cat that will work. also you can cut the cat out and not get a code, if you know how to do the fouler mod takes a few mins and works perfectly
