What are the advantages and disadvantages if i remove the catalyst from h25a v6 enginen where it located 99 suzuki grand vitara
now that is like the most deep question ever posted here.
first what will happen is the rear 02 sensors go dead. (o2 now missing or just cat gone)
and" NSA reads all internet traffic and tells EPA and then the black helicopters, land or "repelling swat" land."
the PCM on all USA cars. the EFI engine brain
monitors the performance of the CATS, by law at all times. (OBD2 USA system monitors by EPA edicts.)
and when fails sets the CEL lamp glowing and smog tests fail for just that. So the smog man fails you in 1 nanosecond, (that be a bummer)
and code P042x sets. (cat performance dead)
there may be PCM fueling issues, like hesitations due to this radial change in VE, volumetric efficiency.
But on this MAF based EFI as this is, the MAF can correct all air flows, and you may see no changes in performance, .
You might see see more engine power due to VE is higher.(less back pressure)
only say up hills, or passing.and only wide open throttle.
lower fuel economy, if you use more power it burns more fuel, a human machine relation ship.
one more CON, is if they can prove you did it, you get fined.
but that takes leaving a paper trails and or witnesses.. (my eyes are closed)
it is ( illeegggle(sp) to do in USA EPA regs, (sp, cant use real word ,its profane here)
not seening the actual mode in person or photos, I say....
if in doing so, the front oxygen sensors are upset the EFI goes nuts. Upset has many forms.
goes nuts 101'
1 removed o2. fuel rates can no longer regulate.
sucks fuel and runs bad.
2: air leaks or cracks created there or bad gaskets due to non stock parts.
all air leaks in exhaust here, cause 02 to go nuts.
and will burn fuel like a pig.
(due to the + and - pressure waves in the exh pipe)
lots of smog, all 3 nasty gases hit mother earth.
HC unburned fuel.
CO, deadly gas, "horrid"
NOX, causes acid rain or burned lungs.
those cats are really 3 cats in one, called 3way cats.
at the least.
the SHORT answer
CONS , many.
PROS, only pro is save money on dead cats.
same answer all USA cars.(since 1979?)
