Primary Cat delete with out ECU tune // Good or Bad idea??
Hi guy ~
Jump right into the topic.
My car is 08 63 with BMC filter/ PLM short header / Secondary cat replaced
with 3 inch Xpipe / Resonator replaced with 3inch pipe.
I'm thinking of doing EUROCHARGED EUC tune soon but just wondering
If I could take out stock primary cat and just install 3inch down pipe .
Probably will have to drill four holes for O2 sensors to go into place ,
I was under the impression when primary cats are gone , with out a proper
ECU tune car will go into a limp mode .
what do you guys think ?? Since I live in CA , I do need to take SMOG test.

Great idea but not for CALI --CA is too strict and you can get popped much easier than other states. too much trouble and expense dodging the SMOG for such marginal gains.

You should only get a check engine light with no cats but Jerry can turn that off for you as well.

You may look into making flanged race cats that will pass smog test and then also have a set of flanged streight pipes to race with. Yoiu just bolt them in or out, when you need smog or no smog.
You should only get a check engine light with no cats but Jerry can turn that off for you as well.

Wise decsion --- we are pretty lucky -- or systems are not that restrictive--- except for the OEM manifolds on the E55 --
I only did it because i wanted more sound for cheap -- E55 mufflers are really quiet
