Yes

I ordered an o2 bung and sensor wire extension to place the o2 sensors around the secondary cat.. But I will not install the bung and sensor until a few days after. If I throw a CEL in the interim, will it go away once I fix the issue or does it need to be reset?

Came in today, it looks surprisingly good for a brand that I would assume is crappy.

Installed my header today and it sounds amazing with no rasp at all. I do hear the flow of air at some rpms that others have reported. I might get a wrap for the header, I heard it helps.

Exhaust system consists of Tsudo UEL header and Top Speed Pro-1 axle-back, everything else is stock.

I tried taking videos but the sound was way off, it came out better using the sound recorder on my phone.

Sho does. Add a catted front pipe for a bit of aggression.

@invaliduser which pipe did you get and how does it affect sound, I'm pretty content with sound as is minus the airy sound. Just curious.

Are you guys getting that hissing air type
of sound that almost sounds like a leak? All my connections are solidly torqued except for one on the drivers side that I couldn't get to but I used a regular wrench and got it tight so I know there's no leak.

[invaliduser]

Yes. I have the same "airy" sound. I have the catted tsudo front pipe and cat back.

It adds a bit of growl to the low rumble.

I got the air leak type noise too. But I double checked everything, it seems normal. I used the bigger gasket

@zERoTu Factory overpipe?

Got a P0420 (catalyst efficiency system below threshold) code which would come on, turn off for a few days then come back. Installed o2 spacer, and now I'm getting P2096 (post catalyst fuel trim system too lean). Is there any washer or any type of trickery I can do on the spacer?

My plan if all else fails is to place the after cat sensor after the secondary cat since I already bought the parts to do it.
