Motorsportpartz or Tuningpros headers direct bolt on?, How much gains to expect with open air intake Options

[onnaj]

I'm about to buy this or this header to add a little more noise and a little more punch with a good look under the hood.

Will these be a direct bolt on? Will both the o2 sensors hook up or does my Celica 7afe only had 1 o2 sensor?

Thanks!

I'm pretty sure the tuning pros headers are from ebay. I have those exact headers on my car . There actually pretty ****ty . The material is crap . I have to rethread a couple of bolt holes on the header itself because the engine rattled it around so much it stripped the thread lol. If you still choose 40 doller headers from eBay , you will need to use half of your stock down pipe, and the half of the down pipe that came w the headers ( the part w the co2 sensor. Or else the pro tuning headers down pipe won't work . I'd go legit now that I've gone the other rout haha
