I've had my HKS exhaust for about a year now and recently I've noticed that it is not as loud as before. I did a quick inspection of the bolts and everything seems to be on tight. Maybe it's the Texas heat? I also have an AEM CAI ~ not sure if a dirty filter has anything to do with it.

Thanks in advance.

 

Did you notice a power loss when you combined the CAI and exhaust?? I'm looking into getting a dual system and the only thing thats holding me back right now are the stories that I've heard of people loosing power when t hey have a CAI and then add a dual exhaust. I'm not sure if the same is true for a single outlet system.

 

Usually an exhaust tends to get louder as it ages. But who knows?

Carbon and soot build-up tend to mellow the tone a little .....

 

Are you missing any small pets?

 

How come you sold the AEM EMS, wereb't you the one who succesfully got some power?

 

drivability? sucked?

 

your just getting deafer.

 

Wierd. Can't speak for the HKS on the S2K, but the HKS Hiper that I had on my GSR got loud as hell so I got rid of it.

I think JDM has it.. Its getting louder AND you're getting DEAFER!! hehe.


SEV,

I sold the EMS and everything else on the car because I was going to sell it. I have so many toys as it is and the S is the slowest by far. I was getting tired of that. Anyways, my wife convinced me to keep it. I kept the Toda Cams and bought new Spoon stuff to replace the parts I sold. I decided this time to go with the Vafc instead of the EMS. My main reason for doing that was because I am going to wait for the Power FC to come out. I have that system on my other two cars and have had great success with it. I think that once it's available for the S in the UDM, I will make more power with it than I did with the EMS.

For the record though, I hit 224.7 with the old setup and the EMS. I added the Toda cams and hit 237.6 rwhp. Not bad for N/A.
