Tune ? for catless downpipe
do you have the stock dp? and just slapped the cutout before the cat?
so the only thing that happens is the check engine light going off?
im sure the codes do go off but just wanted to make sure if it would make any type of difference damage wise, to the computers or watever since there would be no exhaust going through the sensor by the cat..

hmm well im thinking about it, and what would be the difference if i swap the downpipe for the catless one i have as to if i moved the cutout up to the stock downpipe with cat, but before the cat...
would it pretty much throw off the same codes?
i do plan on tuning but not now, i do want to keep the cat thogh so if i could be catless wit the open cutout before the cat, but still be able to have quiet exhaust with the cutout closed then ill just go that direction, im looking more for noise rather performance right now, once i get the cash to tune her ill probably get the 3in c/l dp on her...
what are your thoughts on just replacing the cutout before the cat on stock dp instead of putting a catless dp?

Ive had my check engine light on for a few months now.. went to autozone for the scantool and it came up as the Cat sensor, which makes sense given im running a full open DP...
Mechanic friend mentioned when some codes come up they can directly affect how safeguards and protection modes impact on driving. Car has been acting a little funny lately could this or any of these codes tied to behavior?
