There are no
emission tests and inspections in my local area, and annual safety inspections are a breeze; since they are not required to fail the vehicle if the catalytic converter is not present. So any legal concerns are not concerns.
Reason why I'm considering this is I've helped friends delete the catalytic converters on a few Dodges recently, from base line models to SRT models. The results are pretty overwhelming considering what cost and effort is put into the project ( results were spinning tires continuously from stop to gear three after the converter is deleted.). In the words of a few boy's at a local performance shop, it's free horse power!
I'm considering removing the pipes from the exit of the manifold to the first resonator, and just hallowing out the converters "innards" as they are and cleaning everything up nice and neatly. Then there is the option of having custom ones done up to exact spec in stainless steel (straight pipe so to speak). Either way I go here, I'll be required to purchase some valve bodies for the O2 sensors to simulate the air constriction that the converter is designed to do.
My concern is the PCM will not be able to compensate the A/F ratio's; that said, we have more then a few members running 4L stroker's off these PCM's no issue? This was an issue on a baseline Neon, tripped a lean bank one every few minutes, but ran incredibly for what it was. But those PCM's were designed for nothing much more then the 2.0L anyways.
Can anyone elaborate on the thought? I'd rather have the opinion of a few LH veterans before I start paddling down river!
All I'm looking for is a fun project and maybe gain a few horses and some torque for kicks, not compete with the nitro dragsters. :P
