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 :D

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 :P

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 :banana:

      R35 GT-R production ends after 18 years

      By Rezz · Posted

      Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R.

      R34 25GT Engine Light 21

      By MBS206 · Posted

      21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.

      Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.

      RB25DE NEO with Haltech ECU

      By MBS206 · Posted

      Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
