Hello...
I was just wondering if you install an intake system, do you "have" to install an exhaust? or new mufflers?

and which out of muffler and intake gives more power to the car when installed separately...

Please, anyone who knows about this tell me!!!!

 

ijk,
You don't have to install an exhaust. But it does help to get a few more horses. Plus it usually sounds nicer. In my experience usually the CAI gives more power. On my dad's G-35 sedan we have the Injen CAI it's rated at 12-14 extra Hp. We plan on putting on the HKS Sport muffler when it comes out. Check out the HKSUSA web site. Remember the Engine is just a big air pump, The easier it is for air to come in and out of the engine the more power is produced. Hopes this helps, NismoV35

 

I checked the Hksusa website. There is a listing now for the sport muffler for the G35.

 

whats CAI? same as intake??

and if I do install intake, do I have to install new muffler, or is the muffler on the G Sedan good enough..????


or....would it give more power if i only switch the muffler and forget the intake...???

 

CAI = Cold Air Intake Draws in Air outside the engine compartment The Injen RD1990 The air filter is located right behind the front bumper in front of the Left front wheel. Only thing is you have to watch out for Large water puddles, Flooded intersections, Because it might take a Large Gulp of water instead of air. Once it reaches the engines cylinders and Pistons Water does not compress like air does = Cracked engine block and damaged pistons and pretzel twisted rods But power wise I would go with the Cold Air Intake before the Exhaust......

 

then...do I have to install exhaust when I install Intake?? or can I just install intake by itself???

 

You can install either one by itself without the other.

Also be aware that a larger exhaust, while provided a slight boost in peak HP, also gives you a slight drop in low-end torque.

so... I guess if i had to choose one.....Injen CAI is better bet for performance increase instead of changing mufflers???

 

so... both is not going to improve the performance???

 

I think the point that they are trying to get across is that either one or the other, and even both combined will definately increase power, but at the sacrifice of low end torque. If you are using your G for daily commuting in stop and go traffic, then the difference will not be as noticable as open highway driving and that might not be the mod for you. I feel that it is a waste for me to get those mods since I do drive in the stop and go type of situation. I am currently looking for a way to kill the learning algorythm, and to get the ECU (Engine Control Unit which is the main onboard computer that controls how power from the transmission and fuel mapping is distributed) to behave more in line of the coupe's ECU. I will probably get the above mods anyway since I am a gadget hoe. Oh, definately get the K&N filter. I hear good thing about the filter. Good luck with your decision.

low end power meaning acceleration????

so it would make 0-60 performance worse????

are the ECU chips out??? or is there any other mods that are out there ???

 

why didnt you like it???
