Hey everyone,

I picked up a stock 2006 G35 coupe 6MT with 70k miles in January, 2019 and is my daily driver. I have been reading through all the mod debates and advise threads. Unfortunately, most of these threads are more than 10 years old. So I wanted to ask all the people who are currently modifying their G35 6MTs now or have already went through all the bolt on mods for advise on my G35 build plan.

So far, I have added an oil catch can, Injen CAI, BC Racing true coilovers front and rear, and just ordered Aodhan DS02 wheels 19x11 rear and 19x9.5 front. I know the wheels are reps but I don't have the money for "real" wheels right now, I would rather spend the extra money on performance mods and get better wheels later. I want to keep my car NA and do not want to go forced induction. Money is not a big problem, but at the same time, I want quality mods for reasonable prices and don't want to have to upgrade my mods again by going cheap in the beginning. The goal is to have a reliable G35 with some decent power and exhaust note. I plan to take my G35 to the track for drifting/autocross once every couple of months and still daily drive it. My plans in order of next mods:

1. Motordyne Iso Thermal 5/16 Plenum Spacer
2. Motordyne MREV2
3. Headers???
4. Motordyne Shockwave TDX2 Catback Exhaust System
5. Motordyne ART Test Pipes
6. Hotchkis Adjustable Stabilizer Sway Bars
7. Soul Function Front Strut Tower Bar
8. Mishimoto Oil Cooler Kit
9. Dyno Tune with Uprev Osiris Tune
10. Cosmetic mods - New front bumper, side skirts, duckbill trunk...

I plan to get the plenum spacer and MREV2 together and the shockwave and ART pipes together. I am not sure if headers are worth it and if I do get headers, I have read about everyone either paying $350-$600 for install only or spending 5-7hours installing at home. Also, I'm not sure if I should get shorty headers or longtube. If I get longtube headers, I would not be able to get ART pipes. Will my stock headers be restricting the Motordyne Art pipes and exhaust? My question is your thoughts on my plan and if there is any other mods I should be considering. Thanks.
