no more aircare program lu~ so is it still risky?

$3xx can't do much other than cat upgrade.  Reflash is ~$5xx.

Tires and suspensions are $1k+

Cat is not risk la...if it triggers engine code it will probably be your secondary O2 sensor which you can pretty much ignore if there's no AirCare.  I think that O2 just measures the cat efficiency; main input for air-fuel should be the primary O2.

Wah . . SB .. may be you should come and install the Cat C for me then ..

No air care here ..

LOL

ACC-HE

Hmm.. still thinking if it worth $300...

Most said it doesn't introduce lots of additional noise, just a deeper tone, which I don't mind.

Actually I forgot, you can't ignore secondary o2 code because even that will put the car in limp in mode which hurts performance.

CP, I haven't touched cars for ages la. If no AirCare then just run straight pipe no cat la...haha but again not enough backpressure will harm low end.

o2 code wont have the car in limp mode ... it might run in open loop and you can always run an defouler in there

shutterbug

yes BarF1 is right, open loop is what I meant.

ACC-HE

the cat I'm looking at has defouler built-in.

What do high performance cat usually cost?  Is $300 expensive for a cat?

Catpiano

$300 is not expensive wor .. consider  TSX is ~ $40K .. so 1% of the car!

It is not like spending $10K on a S/C ...

$300 is not expensive la...call up Acura and see how much they quote you on a stock cat!
