NISMO owner - suggestions for modding

A word of caution on test pipes. Know the smog laws in your state, because you will most likely fail a visual inspection. Also, you will have to deal with the exhaust smell without cats. Might not be a big deal to you, but I suggest you search the forum for some other threads on the subject before jumping on that band wagon.

I'm a Nismo owner, and went with Swift springs, 15mm spacers all around, a Z1 25 row oil cooler, K&N drop ins, and am waiting on a FI CBE. My understanding is that the stock headers and cats flow quite well, and except for more exhaust noise, switching to test pipes or HFC's don't really gain you all that much.
