A header for him would still leave an empty space that needs filling with either a stock cat, high flow cat, or test pipeJust get headers. Skip the catalytic converter.
Just get headers. Skip the catalytic converter.
I wouldn't think so. Should be in the pipe after the cat.Wouldn't you have to remove the 02 sensor too?
Anything after the cat doesn't matter. Gonna be before or onI wouldn't think so. Should be in the pipe after the cat.
However if he's looking to stay quiet that's not going to help. My cat went out and I just went with OE only because I realllllly didn't want to be louder than I already am. But if that's not an issue I would say go for it.Magnaflows high flow cat is cheaper than oem and flows better.
Disco.For the 00 Civic EX, the secondary O2 sensor screws into a bung at the top of the cat, so yes you'll need to remove the sensor from the cat when replacing it.
Yup. Just make sure you soak that ish in PB (especially the rear three), it'll be much easier. I almost started crying I was so pissed I couldn't get them off. I'm a weak one, no upper body strength.Its pretty easy. 5 bolts/nuts I believe. 2 in front 3 in back
