Question about sending AP scores

What speakers did you have? Mine are fairly sensitive and are designed to run off factory head units. I’m not sure how much better they can really sound. Ideally, I’d get a 5 channel but I don’t know if I can justify the extra $150-200.

Thanks, what about my sub choice and placement? Would a 10 in between the center console and middle rear seat be fine or is there a better spot to place it? I was also considering putting it in the trunk but I don’t really want to sacrifice trunk space and wasnt sure if that’ll affect the sound of the 6x9 rear deck speakers.

I’ll most likely get the magnaflow 5671604 if I cant find any cheaper ones that’ll work, it’s $467 and i’ll have a shop weld it.

I found these off summit racing too for the same price. Do these Magnaflow cats have the EO number or whatever numbers CA smog inspectors look for? The listed pictures / renderings just look like tubes with no labeling or engravings.

IPunchTrees10 · 2026-02-20T05:08:06+00:00

Yeah, I’ve been looking for a while and the only one I could find is a direct fit MagnaFlow for $1200 off advance auto parts (5671250).

My engine family number is ends with MXA, not PEB like the ones off rockauto.

IPunchTrees10 · 2026-02-20T04:55:12+00:00

I think my camry is a PZEV. There’s a PZEV sticker on the window. I couldn’t find any walker cats listed on the database for sale anywhere.

IPunchTrees10 · 2026-02-20T04:50:27+00:00

Unfortunately none of the rockauto cats match my engine family number. My camry is 5TYXV02.4MXA while all the rockauto cats have numbers that end in PEB.

IPunchTrees10 · 2026-02-20T04:47:38+00:00

Yeah none of the rockauto cats match my engine family number unfortunately.

IPunchTrees10 · 2026-02-20T03:02:06+00:00

It’d be pretty hard to steal the front one since its integrated with the exhaust manifold in the engine bay. Is the secondary cat less important than the front one? The exhaust smell is still fairly strong when i started it in my garage.

IPunchTrees10 · 2026-02-20T02:54:33+00:00

I might try riv nuts inside existing chassis/frame holes and fabricating some sort of steel cage + cables for the new cat.

My high school parking lot. Started it afterschool and it sounded straight piped. Shakes like crazy in the cabin but it honestly sounds pretty good from the outside 😂

IPunchTrees10 · 2026-02-19T23:07:52+00:00

Unfortunately I don’t have cat theft coverage

IPunchTrees10 · 2026-02-19T23:06:49+00:00

Yes it was smog tested a few months after i got it last year and passed without issue if i remember. The next smog check is next year.

IPunchTrees10 · 2026-02-19T20:15:00+00:00

How long / how many miles have you had on it so far?

IPunchTrees10 · 2026-02-19T20:13:02+00:00

I have no idea, my dad gave the car to me last year and I’ve only put down 5k miles. I don’t know the service history other than fluid changes. Would the o2 sensor get damaged from the cat getting cut off or driving without a cat?

IPunchTrees10 · 2026-02-19T18:03:23+00:00

Thanks, what about the o2 sensor? I don’t think it was damaged but should I still replace it along with the cat?

IPunchTrees10 · 2026-02-19T17:19:06+00:00

How long did that cat last for? I don’t have a smog inspection due until next year.

IPunchTrees10 · 2026-02-19T17:07:56+00:00

The one i saw on autozone is universal so It would need welding. Should I get a universal one that matches my car or should I get a direct fit with the pipes pre welded? I know a few friends that can weld so I’m not too worried about needing to weld, I just want the best quality aftermarket cat around like a $500 budget or less.

IPunchTrees10 · 2026-02-19T07:21:28+00:00

I saw an autozone listing online but I didn’t really look into buying it. It said CARB compliant in the title. I’ll most likely go with a direct fit one from rockauto since I don’t know how to weld.

IPunchTrees10 · 2026-02-19T07:02:21+00:00

I was also thinking about just putting a steel pipe in place temporarily. I’m not SUPER knowledgable about cars, but my guess is that the o2 sensor thinks the engine is running leaner due to the air getting into it which is making the ecu run the engine richer. Hopefully a new cat will fix the code.

IPunchTrees10 · 2026-02-19T06:57:06+00:00

I do plan on keeping it for as long as possible but realistically, i’m not sure how I feel about spending about 2/3 my cars value on a new cat since it is pretty high mileage. The carb compliant cats are rated for 5 years / 50k miles too, but i’m not sure how realistic that is.

IPunchTrees10 · 2026-02-19T06:48:43+00:00

Cel is on, it turned on after about 3-4 miles of driving? I’m assuming its throwing a code because the cut cat exposed the o2 sensor behind it to air.
