i'll post the write up on the modification thread as soon as i get some pictures of my underbody
and for the High flow versus test pipes? if your pocket is deep enough get the HFC's why? you might ask? because the gains between a test pipe and HFC in a NA car are MINIMAL this is not some myth but NA cars dont really need test pipes, However, if you decide to TT or SC ur G35, go for the test pipes because with FI test pipe gains are huge, or just above 10whp.
But why i got the test pipes again? 125 shipped no tax ( where i live ), compared to the average price of high flows cats which are around 500 minimum, the nismo one is about 1 grand, now all this just for 5hp on an NA car? i would rather buy some dinner with that money . but for all you extremely thrifty people go for the HFC's.
ALso the smell and CEL, i didnt get my check engine light untill today wen I went driving in the mountains, lasted around 50 miles without the CEL. The smell? well its horrible, i have a cold right now and i can smell it and it's pretty bad.
Gains? GAINS! gains? well a few things i noticed after taking the car for a nice hard drive today is well there are a few gains. I dont know if this is true but it feels like my rev is faster now, i noticed this when i was driving normally and i started to shift at 3.5ish compared to my regular 3k rpm for my normal driving, the 5 hp that is suppose to be gained isn't really shown here but without a doubt yes there has to be some gain, if you have ever looked through the g35 cats, its about a feet of filtering hence why its a LEV.
well i hope that helps, this concludes my opinions about the test pipes feel free to ask any more questions i'll gladdy answer.
