Mine is an 01 Prizm (I think I should put this in my sig, might make it easier for ppl trying to help me..lol...) and I got it used. It had 134K on it.

i hope this picture shows why i was getting EVAP codes.

Ouch. That thing sheared right off.

I was looking at the AC Delco O2 sensors for the Prizm, and they are pretty much the same price at the dealership.

why? They carry Denso for $81 and $97 isn't that what these cars have on them to begin with

</div> Didn't know that. Since mine is a Chevy Prizm, the guy who installed my Magnaflow higflow cat told me that I would also need to get new O2 sensors from AC Delco. Never did that though.

</div> Yup. That was the muffler shop guy though. My mechanic was pretty good. He told me not to get them since my O2s were in excellent shape. I put 8K on my car since March (it already had 134K on it) and nothing ever happened for me to replace the O2s.

SBUBandit · Aug 3, 2007

How do you like the magnaflow cat? Mine is a Prizm as well, and I am saving from now till tax time to get it fixed. It needs new motor mounts, and some exhaust work. I'd like to find a TRD muffler for it and probably replace the manifold, and it needs O2 sensors. Not sure about the cat yet. And if I have any money left I want to have the headliner redone. I have a dealer installed sunroof, and whoever put it in is an idiot. They pulled the headliner material so tight it is all falling down.

</div> Magnaflow cat is awesome. I like the improvements in gas mileage and to a certain extent, the power (compared to the old one that was dying). The cat is stock dia though, and I'm tempted to change it to a 2.5" one, but I don't know how my car will take it.

SBUBandit · Aug 3, 2007

how much did you pay for the magnaflow cat. I am redoing my exhaust next spring, and I will probably stick with stock diameter. If you end up deciding to change let me know, maybe I'll buy your cat from you. I will probably go with a new stock manifold, new o2 sensors, perhaps a magnaflow cat, stock resonator, and if I can find a reasonable price, I'd like to get a TRD muffler. First though I am getting four new motor mounts and filling in the indents in them with acrylic to stiffen them up

</div> A nice TRD muffler with stock reso and piping would probably not do you any good, and you might end up with a farty sounding exhaust. New stock header is ok, and if you port it properly, you might have some gains and magnaflow cat adds some more. You can stick with stock sizes upto the cat, but after that, I would recommend 2.25" dia reso and piping minimum (mandrel bent for least restrictive flow) and then the TRD muffler. This will be much better and will not have a farty sound.

</div>The TRD muffler w/ the stock resonator will sound fine if not better than a custom setup. The TRD muffler itself is more baffled than a straight through Magnaflow. A high flow cat won't gain us Corolla drivers that much. Its a negligible amount of power. Don't waste your money on that. Normal cats will do the job just fine.

</div>When I got my custom Magnaflow setup, it was 200 for the Muffler and resonator and 100 for the custom mandrel bent cat back tubing. The owner welded the whole thing for me for free.

</div> TRD is baffled? Didn't know that. The cat does some good, maybe not too much and its not that expensive if you get a stock size one. I did experience a good improvement in mileage on mine.

GSE21tuner · Aug 4, 2007

Most likely you only regained the original mileage it was supposed to get. A bad cat will reduce your mileage. Have you installed your ELP CAI?

</div> No not yet. Kinda stuck with the wrong sized spectre mount. And I need to seal up that other hole. Been a little busy, so did not get a chance.

that reminds me, i need to install my ELP CAI now that I passed smog!! YAY

</div>Unless we all decide to do battery relocations. That way we can have a more efficient CAI and have a spare ELP CAI to sell off. hehe

what was this thread all about??? ohh yeah!!! my adventures at the smog check place and my annoying CEL!!! let's get back to that... geeesh!! trd mufflers?? and magnaflow resonators??? what's that got to do with smog?

I'm kinda leaning towards avoiding a welded setup just so it can come apart if something needs replaced down the road, and also to avoid cracking anything if i run into the motor mount issue again

GSE21tuner · Aug 6, 2007

Yeah, I really didn't want to get it welded but it was the absolutely last option.
