Please assist with the in-depth details of these cars

 

In terms of horsepower? They are all the same (330hp)

 

Assuming you're talking about the coupe. If you have the sedan they're all 328hp. Sedan is also down 1 ft/lb of torque with 269ft/lb vs 270ft/lb. Sedan is still negligibly quicker. Any G37 (including the IPL) will all be close enough that the only real difference is the driver.

 

Google

 

Coupe: 330hp
Sedan: 328hp
IPL: 348hp

In case Teh Google is broken

High numbers for this class of car, but it's no lightweight.

 

what gives ipl more tq nd hp over sedan and coupe?

 

Different exhaust and factory tune.

 

so why aren't ppl using ipl exhaust and finding tunes 348 is pretty good number

 

https://www.ebay.com/i/172746602225?chn=ps&dispItem=1 found this but not sure if will work for 09 sedan.

 

I suspect Coupe owners would, but unless you find one used, an aftermarket exhaust will still probably be better, although marginally so.

People do tune this car. All the time. Take any G37, open the exhaust and adjust the tune... you'd have similar numbers. It's not magic.

 

It also depends on what color car you have. Certain colors are just naturally faster.

Any aftermarket dual exhaust and a tune will get you to "IPL" levels. Honestly a tune will do far better than an IPL ECU and probably give you a nice midrange advantage over the factory IPL tune.

 

i wouldnt get too excited over 18 hp. its annoying how nissan does these little hp increases like it makes much difference

 

IPL exhaust is a true dual, but my tuner says it's still pretty restrictive. It just sounds alright too.

I have an IPL and have been in regular G37's before. Power pretty much feels the same.

 

I hear red's the fastest.
