1. Apex N1
2. Invidia
3. Tanabe Racing Medallion
4. Spoon N1
Let me know which one is the best for the S2K. I'm looking for the lightest exhaust that produces the most HP w/o losing torque. Your help is appreciated.

 

I have the Nvidia. It is much, much lighter than stock (I'd guess 15# total). I don't notice a loss in torque for daily driving. Power...I dunno, even the best don't add much.

The only complaint I have is a resonance from 3-4000rpms. I've heard swapping the stock resonator pretty much fixes this so I'll be looking for shops to do this.

The Nvidia is LOUD. It is not too bad with silencers, though. The sound in VTEC is Ferrari-esque.

 

how about espelir JGT500??/
they look great and sounds nice.... also full stainless
check on my sig

 

I've got the Spoon. Out of the ones you listed, it is the best sounding and probably the lightest. It is quite loud, however. It also features a more subtle tip than the others. Overall, in my opinion, it is the best single exhaust out there besides the Amuse titanium.

 

I have the apexi n1 and it sounds really clean to me. Down low, it is deep and growls if you blip the throttle. Up top, the sound kind of dies down and you can hear more of the motor. It sounds real good . Like most single exhausts, there is resonance around 3-4k rpm. You get used to it after driving it around for a week or so.

 

I wouldn't expect much in the way of power increase, weight savings can be considerable esp. with a single outlet full Ti (though you might want to invest in a set of earplugs). Check the dyno here:

Doesnt the 70mm T1R with straight pipe make the best hp?

 

out of list you have created...i would pick spoon.

 

Why wasn't T1R on your list?
