Hi Scotty-
1st- My Car Info
- 2002 Toyota Camry LE 2.4l (vvt-i 4cyl)
- Approx 130,000 miles, original motor & drivetrain (automatictransmission, runs/drives great)
- Car also has original Cats and o2 sensors, no modifications performance-wise
To start: I live in Washington State (one of the places that doesn't make the news, we'll just leave it at that) where there isn't Emissions testing done anymore.
I want to replace the Exhaust Manifold (that has the primary Cat on it) with exhaust headers (made of Stainless Steel that are chrome plated), which these headers are made for the same engine (2AZ-FE and primarily used on Scion TC's 2005-2010) but doesn't have the Cat.
I was hoping to avoid throwing any emissions codes by doing this, so here's what I was thinking - these cars (as you are aware) have the secondary Cat on them that the car doesn't read or monitor emissions (from what I understand). The new headers already have the bunghole installed for the upstream O2 sensor, which I would use. I then wanted make a downstream bunghole just past the secondary Cat., and move the downstream O2 sensor there. That way the car "thinks" its still reading data from the original cat but in reality is getting the info using of the second one.
I just wanted to know your thoughts on if this would work, and/or if there would be issues by doing this, such as having to make the length of the O2 sensor wire longer (using an extender) due to moving the downstream o2 sensor further. I'm already aware that it will cause more emissions/smell by removing the 1st Cat, that it will have a louder exhaust note, that it probably will require more maintenance than the OEM setup, and there's a possibility that I would have to have the motor tuned professionally to make it run more optimally...
Finally - I would be doing this for fun- but I also wouldn't argue with anyone that would be questioning my motives or sanity (other than anyone like me who doesn't have a full set of brain cells in their noggin) by even considering to do this to what otherwise be a perfectly good, ordinary, everyday run of the mill "grandmotherly-going-to-church-rig".
Appreciate your time, thanks for all of the advice and help you given on the channel, and keep up the good work!

it's a 4-cyl, don't bother 😆
better to have a reliable car than a chainsaw fart cans.

Well that didn't take long 🙂
come on.... suping up a grandma car? Keep it as a reliable ride and it'll last a long time.
Don't bother souping up a Toyota Corolla,all you'll do is annoy other people. I have a 2017 Mustang V6 and I put axle-back Roush exhaust on mine. It sounds good when you want to go 0-60 in a hurry. When you're driving on the highway the axle-backs get annoying.
Have you ever considered customizing it a bit without making all kinds of noise? You might look into stripes, etc. On a 2002 Corrolla. I put light green decals on my 2013 Ford Fusion (similar to the green of the Seatte Seahawks) . It was dark blue, and I had named it Niagara. There's a museum where my folks live, in Erie, Pennsylvania. I bought a license plate frame, "Don't give up the Ship", also in dark blue. I actually won at an all-Ford car show for most unique vehicle. There were a bunch of different trophies. I had the car's name cut out of the decal.
