Just wondering if anyone using either of these headers with Nitrous in an H22a.

I plan on adding nitrous as the very last thing to my car mainly because I don't want refills stopping me from being able to save money for anything.

I'm at this point I'm thinking about getting a full SMSP exhaust (header, 2.5 inch back 2.5in high flow cat with a 22 inch resonator to a straight threw muffler)

if i get an N/A header it's not going to hinder the performance of N20 too much I;m hoping as I hope to gain most the power from the engine itself not the nitrous.
