I dynoed 212 on a drum dyno, with an HKS exhaust and PRM intake, both items that claim a loss in HP. The HKS is also LIGHTER than stock.

I dont have proof of my dyno though, so take it for what its worth.

 

My friend has the HKS on his S and it does sound awesome!!! I was going with that exhaust until I heard another S with the Apexi World Sport 2...It has a deep tone and isn't loud at all...You can't go wrong with the HKS!!!

 

I too am considering the HKS. So just to sum things up, am I hearing that the HKS Hi Power sounds good and is not too loud? I'd like a decent sound but nothing loud and ricey. If this is the case, this might be my exhaust.

Does anybody know the weight.......

and the stock weight.....

what is the savings in that area.....

 

i think u save about 10 lbs with the HKS

 

I'm an HKS exhaust owner too

I LOVE how it sounds... sure I haven't recieved any power increases but the noise it makes (especially when you go through a tunnel)... gives me a smile that's priceless.

 

buy my amuse, save like 50 lbs and call it a day

 

 

I think the HKS has ~1-2hp gains by itself, which can easily turn into a loss on a dyno, if conditions aren't identical to the baseline.

I almost bought one, but I couldn't stand the idea of something other than stainless steel for the pipes. I've seen used HKS exhausts for sale, and they don't seem to hold up very well over a period of time.

 

I've been wondering about the WS too. Your post is the first I read about that exhaust for the S. Did you end up getting one for your car?

I think it is similarly priced to the HKS. I wonder which is lighter?
