Prolex Kazuma Vs Hks Silent Hi-power

Recommended Posts

After fitting my Prolex Kazuma i knew straight away it was rather 'loud'..

Daza W had quite the opposite with his HKS Silent Hi-Power... and after today i understood why!

Anyway, we swapped them over..

I lost about 6dB easy! sounds more like OEM jobby, but slightly more bassier..

Daza's was amazingly quiet still, but slightly more deeper. I think he'll relay his before and after.

Here are are the two side by side.

Prolex is the slightly golder item.

I forgot to do a sound clip - doh!

Either way, both happy... and if you own a IS200 you have nothing to worry about, it is as Prolex say - Quiet and unobtrusive!!!

IF you own a Tezza... might be best to go for a Silent Hi-Power or the unit which ASP are releasing soon.

:driving:

Nice one guys, both cars are looking good - if the Kazuma is anything like my Hiper was it had a wearing in period which took about 1000 miles - started getting deeper after that - sounded awesome after 10,000 miles were on her, now I've got the twin's on they're just incredibly loud all the time!

they get louder and deeper when they're hot. I love it at the toll booths on the M6 toll, window down, money in the basket, revs up, barrier up, dump clutch, vrooommmm off. Excellent

have you just got a rear section or the whole exhaust

does sound nice but not as loud as expected if you heard the same system on the tezza you would be amazed
