I wonder what the soldering of wires does to the fuel mappping, if anything.

As stated above, the second O2 sensor does not affect fuel mapping in any way, it is only in place to confirm to the ECU that the catalytic convertor is in place and functioning properly. Even with this sensor completely removed your performance and fuel mileage will not change.

No they don't. If you don't get a CEL in the first littel bit, you will probably never get one. I have been installing mechanical CEL fixes on my customer's cars for years. Some cars need 2, or the 90 degree bung method works as well.

I like the anti foulers better than the soldering method. The mechanical method can never fail.

You probably wont get a CEL , but if your state has a sniffer test, it will not pass without cats.

cali yaris · 10-29-2008, 03:55 PM

I love innuendo...

I know it's important to get tested regularly, but...

Kuro, We don't have to smog this car here in CA for five years (then it's every other year). Do you have different rules there?

at3GG · 10-29-2008, 06:45 PM

I didnt mean "issue" like that castrex, i meant having the CEL come on and bug us as we drive. I know its just the ECU doing its job. If i do keep the cat like you suggest, will larger diameter piping after it do that much? Isn't the cat what is most restrictive on our cars? Or is it the small diameter piping?

CASTREX · 10-29-2008, 07:22 PM

I have seen the cats on the inside and they look good. Not very restrictive. Very similar to other expensive high flow cats I've seen.

On my car I did removed the secondary cat and leave the OE primary cat on as I saw no need to remove it.

To me the most restrictive part of the exhaust is the pipe between the resonator and the axle. It's all crushed.

If you are interested on making the most out of your exhaust go for some smooth mandrel bent pipe on 2". If you can't get a mandrel bent pipe go 2.25" pipe.

Removing the cats will net you maybe a couple hp at the top end of the power curve. If you are hardcore and want to go all out then go for it.
But for normal every day driving you won't feel a difference.

In my opinion unless you are planning on doing serious motorsports with your car it doesn't really worth it.

Eventually when you have to take your car to an inspection you will have to instal a cat again. If that is not a problem then do it.

Thanks castrex...I'll be leaving it right where it is.

at3GG · 10-30-2008, 03:33 PM

How much should a custom cat to axle exhaust run from a decent shop anyway?

Around $200-$250 depending on what muffler and tip you use.

If you use a turbo muffler and no tip you could probably get it under $200.

cali yaris · 10-30-2008, 04:49 PM

+1, I got my first custom one done for $280 in Van Nuys.

cali yaris · 10-30-2008, 08:44 PM

Malaya, in 40 years when your car has over 5 million miles on it, you'll get a CEL -- Rockland knows.

eTiMaGo · 10-31-2008, 10:42 AM

I have this midpipe... since just about a year... and not a single CEL...

Truth be told I am quite sure the USDM ECU is way more stringent on the emissions stuff, hence the trouble you've all been having :fronw:
