Would these Work

[redrider07]

I want to get a high flow cat, and would these two work with the Alero? I think they migh throw codes. I know someone mentioned I might need an 02 sensor or something, I think it might throw a SES light with these cats, they both don't have air tubes!

Unless your car is from California it doesn't have an air pump, so no worries.

Ok thanks, what about the O2 sensor bung, I think that is wielded after the cat I believe so I might not need it then?

Yep, it's like 3 or 4 inches after the cat in the pipe, and if you get a new downpipe made for a universal cat it would be no problem for them to weld a new one in.

However, with those prices, I'd recommend you get this instead, Magnaflow so you can trust the quality, all stainless, and it's a full downpipe complete with 3 bolt flange and O2 sensor bung. I have it on my car and I'm very pleased so far.
