Anyone have these or can vouch for them and the difference between fitment, sound , gains? I saw few video but not much to tell the difference.

Thanks

 

i have seen then on a couple s2's they look very nice..... i had the carbon Ti on my subby and the fitment was 100% quality was perfect and sound was the same. But i am not sure if they make a full SS kit for the s2k. if they do not... there cheaper metal rotts out very fast.

 

i've got the newer one on my car... i forgot which one the new one was the hi-power or the hyper...... either way it's the newer one...

the old one didn't have any gains.. and some people lost a hp or two....

as for the new one (one i got).. i didn't get a dyno with just the exhaust to get the difference but i did get my car dyno tuned later with 4ig CAI, vafc II, and the hks exhaust and i got 215rwhp..... i gained 10rwhp with the vafc II alone.......

and i love the sound of the hks, there's barely any drone.. mainly between 3500-3800rpms.... highway cruising sounds great... and it gives off a deeper tone then the stock but not to much louder then stock...

 

Great Exhaust, I just got the HI-Power myself and love it! No drone and great sound! But I'm not too sure about the gains though.

 

I believe the Hiper is the new one. Thanks for the report

 

High Power was the JDM version, where as the Hyper was the USDM version. The Hyper has been discontinued, and Hi power took its place in the US. You can tell them apart from one thing.....the Hyper has holes in the tips for the silencers, and the High Power doen not.

 

so does the new make power, cuz i no the old one didnt make any power, and does it still look the same or is a single now

 

^ i'm sure it made power on mine.... vafc II, 4ig CAI, and hks exhaust = 215rwhp on an ap1 is a nice number...
