P0430 Code after installing exhaust

[RKD25]

Recently I installed secondary dps and MBRP Catback exhaust, and now every couple drives I get a P0430 code, not sure why this is happening since I didn’t touch the primaries or anything emissions related other than the secondaries

Has anyone else had this issue? I’ve already double checked everything I did any everything seems to be in order

code usually happens with an exhaust leak. i would double check all the connections and make sure bolts are tight as possible. i know the clamps that came with my MBRP were absolute trash and could not get them tight. I swapped them out with some from advanced auto and was able to get a good seal.

Got it, I’ll pick some up after work and throw them on tomorrow. I reckon it’s probably starting to leak after getting hot cause I’ve only ever messed with it when it’s cold
