Long Tube Owners…

you been having good luck not throwing codes? I splurged for the greens but keep throwing a 4030 code.

I threw codes with the standard Kooks cats, and thought the greens would be better ($1700 mistake). I threw codes until I had it tuned... my tuner quoted 30% leaner than it should be... no codes after the tune. Also recouped about 50% by selling the non-green cats... lesson learned for sure.

I had greens on my gt500, 4+ years no codes. I can’t tune out the monitors but maybe pull a log and a tune update is what is needed.

Once in awhile it would throw a code the first 6 months. I haven't had one show up in some time now. I just have the extensions on the rear 02 sensors. No tune and no cats.
