Ive been looking for new Headers w/ Cats because my car is at 160K, and ive come across these ebay headers with cats already integrated into them. How long would they last realistically? Not as expensive as MagnaFlow, has both cats to avoid the CEL, what do you guys think? worth the buy?

Im no expert on headers but they look pretty ugly to me, crush bends and poor design.

They will probably flow exhaust gases though not sure what the cats are like for actual smog readings, but looking at the flow path for the front of each bank compared to the rear on each i would expect power loss as opposed to any hopeful gains

Well, you could go with a catless header and those 990 degree o2 spacers with minicats.

That's what I did, and I haven't had a single CEL in approximately 248 miles of continuous driving, pulls, and a lot of revving out in 2nd and decelerating to spit flames lol 😅

Make sure to put one on the y-pipe, and another on the header (both Bank 1 sensor 2 and Bank 2 sensor 2)

Every n/a is300 I see with catless headers sounds raspy.

Those look AWFUL for optimal flow performance, like the solar said, the magnaflow ones are the better buy for not much more

I'll chime in with the others that the design and build quality on those look pretty awful, solar's recommendation of the pacesetter headers is probably good. Last I checked the Magnaflow is over $1k though, so quite a step up price wise from the stuff here.
