Haven't seen anything posted about this, not saying it isn't out there though. I know if you get headers, either cattman or hotshot, you have to move the secondary o2 sensors on the 03 max. What about when you get the y + b pipe? What do you do with those secondaries? Are they bunged into the b?

Not sure if I want to go the header route due cost (#1 almost 2K CDN) and to the problems I see a few have had with the vafc2 install (#2).

 

There's minimal gain with the y-pipe on the 3.5's...i don't really think its worth it. I'd save up and get the headers. While a VAFC is not necessary, it will allow you properly tune the fueling to make sure you're not running excessively rich and produce maximum power.

 

Well that's the thing, I don't want it to be a gas guzzler.
