I recently bought the a new 06 G35 coupe with automatic. I only want to change the exhaust, intake and maybe re-program or flash the ecu. i was thinging along the lines of the HKS Hi-Power cat back, 5/16 spacer, cold air intake...etc. what would you guys recomend? i don't want to pay a million dollars but i want good quality stuff. i want more torque, also is there an easy way, other than flashing the ECU, to remove the Top Speed Limiter? . what parts would you recomend.

 

hks is very popular on the forums. intake mods are sound mods only (imo). 5/16" spacer is a good choice. sound like youre headed in the right direction. perhaps some test pipes or high flow cats, too.

 

I like what you have in mind. I would also recommend the motordyne mrev. that will give you noticeable gains. There are some issues with cold air intake so i would pass on that and get a pop charger or ztube and k&n drop in filter.
