What brand Downpipe is this?

[Impulse]

Hello all I’ve recently gotten the P0420 fault on my 16 FiST. I have the MBRP exhaust and I got under to check out the down pipe and saw this. I’m curious what brand is this? I couldn’t find it online

That “L” bracket is what was throwing me off. Thank you. That’ll explain the smell. Lol

It's a catless DP....explain s the inefficiency code of p0420. Need to see if it has a de-fouler on the downstream O2.

It does not. I’ll be ordering one tonight. Or maybe just get an IC and go stage 3 where the code is just turned off lol

Is that a shadow or a cracked weld on that second picture?

 

[Impulse]

It may be cracked I’ll check

It might just be bird crap from a bad weld lol which also isn’t good

Surface Corrosion....I got $5 on it.

only Time will tell ! I’ll check in the morning it’s almost 2am. My 3 year old decided to nap instead of sleep 😢

There is corrosion there, but i shouldbt be creeping under the weld. It looks like a gap. Vibration and thermal expansion/ contraction will break under a bad weld

I think it's the "Chrome" Finish coming off due to heat.
