For those you have installed an aftermarket dump pipe, do you need to get a bigger O2 sensor? I read a DIY thread on NS.com where the guy needed one, but that was an s14. Same needed on s15? Would a thread minimiser really be that bad?

I think it depends on what dump you're fitting. I had no issues with the CES one.

Sweet thanks guys :wave: . It is a HKS style rip off by the way. Quality looks pretty good from just a visual inspection.

Read an article from a guy who compared a HKS to a CES dump on the dyno. CES was slightly better above 4800 rpm, but with the power I am going to be running once first round of mods are completed (around 180 rwkw), the difference would probably be negligable. So, elected to go for the el cheapo hks style option. It is only 2.5", with 3" front pipe, but will be better than stock :) .

The stock O2 sensor is actually already fitted with a thread minimizer.
All I had to do with my dump-pipe was to get the whole lot of (sensor and minimizer) and fit it to the new dump-pipe.
But most dump-pipes doesn't need the minimizer.
