Should I also get a hi-flow cat converter
- Thread starter GP24
- Start date
Two question about running catless:
1) Will that effect my emission test?
2) If I run catless would I have to buy a pipe to replace the converter or should it all be the header set?

Answer to both...the headers come with everything to bolt up to a factory catback system...flange and all...but it comes with a race pipe, ala...no converter. But yeah, it all bolts up just fine with everything included.
And unless you know someone that can pass it, then no, you will need a converter...

Catless is better.
And no, it will fail emissions. If you get the O2 sensor faker from zzp, it will keep you from getting a trouble code. But if they use the sniffer, it will still fail.

I plan on moving within the next 1.5 years, so I was just concerned about any issues I would face.

Move to Missouri or Kansas.
Honestly, no one gives two sh1ts here about anything.
OR, buy a fake 3" cat from Frozen Boost and just bolt it in there...to add, what year is it? Because you can only run an o2 sim with '97-'00 cars...after that you need to actually run the rear o2, just remove the codes via the PCM.

So the O2 sensor can be tuned out? Was it the EGR that couldn't be?
