Hks Hipower Exhausts?

[vinnie32GTS4]

hey guys

im looking at changing my cat back and have heard good things about the hks hipower exhaust and have heard a couple on skylines but they were silent hipower ones

so what i'm asking is whats the difference between the hipower and the silent hipower and also the 409???? im so confused lol

and also your opinions on which one is better and why

oh and just a heads up my current exhaust is a custom 3" split dump/front with a 3"hiflow cat and some jasma 3" cat back with an oval muffler which is way to quite and restrictive, hence the reason for changing the catback.

thanks in advance

I may be wrong but I think its just the noise level. I have Hi Power on my R34 GTR, love the sound of it

The HI-Power Silent is a full 'shine' grade stainless, 304. The HI-Power 409 is made from an exhaust grade stainless, 409. so not shiny, the cannon at the end is, but not the pipes. the HI-Power Silent usually retails for around $100 extra as well.

i have a HI-Power 409 in my stagea and am very happy with it. very good quality, no drama installing it, eveything lined up perfectly.

mine come with a pre muffler out to a cannon. nice sound, not too loud at all, well under the legal db level. i dont think there will be much difference in the loudness between the two, maybe just a slightly different tone to the note because of the different materials they are made of.

There is a difference of about 5dB between the 409 and the Silent models. The 409 being slightly louder, obviously

I am very happy with my Silent Hi Power system. I am running HKS from the turbo al the way back. It has a fantastic note and is not too loud, but loud enough to give you a grin

you want an awesome system with an awesome note, grab yourself the blitz nur spec v system. The best i've ever heard and very good quality.
