Hey guys ..wut's up ?

i just installed my nismo headers today ...actually my car still in da workshop ...am puting HKS exhaust system and now the nismo headers with stock cats , and without intake ...i put nismo CIA short tube , and i really lose HP ...i don't know wut to do next ....am planin to buy HKS CIA ...after that do i need tuning , and removing the stock cats will increase my hp ?

thx

 

removing your stock cats will most def increase your hp....once you have the headers combined with cats, HKS exhaust, and CAI purchase a AAM piggy back ecu and get her tuned.

 

just get an 06 airbox. not the greatest looking part but def helpful...

 

replacing your cats will probably produce the same HP as your headers/exhaust combined.

 

If you get hfc or test pipes, your power will definately increase in the higher rpms. A good mod to bring back the lower end torque is the motordyne 5/16 spacer and mrev. I would wait to tune it until I get the spacer and mrev(lower plenum). The intake situation is debatable. I think the majority of people would tell you to get a k&n drop in filter for your stock box or get a 06 box and a k&n drop in filter. Some intakes will make you lose power.

 

dontuse nismo intake its not really a cai its in the engine compartment is more like a massive flow or short ram in my opinion


try test pipes or highflow cans and a k&n drop in or a real cai
