Dazzi Posted May 16, 2008 Share Posted May 16, 2008 As title, im looking at the HKS Hi power 409 and the Silent Hi power (both na version). I don't want it silly loud like my old Nur Spec R, just want it a bit more beefy that my Kakimoto R Im thinking the Silent Hi power is quieter but need confirmation from the na boys Cheers Quote Link to comment Share on other sites More sharing options...

Nic Posted May 17, 2008 Share Posted May 17, 2008 The Hi-Power and Silent Hi-Power are essentially the same exhaust, except the Hi-Power uses mild steel mid pipe and stainless steel rear, where as the Silent Hi-Power is 100% stainless steel. Both are rated at 99Db on an NA. Here is a list of available exhausts for the 2JZGE, give me a shout if you'd like any prices.

When I search for the 409 its always pictured without one - obviously I would want the exhaust with this on to tone things down a tad.

When I search for the 409 its always pictured without one - obviously I would want the exhaust with this on to tone things down a tad. The photos used on websites are usually not of the exact car model, but just a representation. Both have a central silencer, the only major difference between the Hi-Power and Silent Hi-Power is the material they are made from. Here are illustrations of each.

Dazzi Posted May 20, 2008 Author Share Posted May 20, 2008 Cheers Nic, The HKS 409 rated at 99db, is that a 2JZGE version? Also do you know the db for a Nur Spec RX? Quote Link to comment Share on other sites More sharing options...

Hi Dazzi HKS quote 99Db for the HKS 409 on a 2JZGE, but this will probably be with both cats still fitted. Blitz list the RX at 91Db on a TT, they don't list the figure on an NA, but it would be a bit louder. cheers Quote Link to comment Share on other sites More sharing options...
Branners Posted May 20, 2008 Share Posted May 20, 2008 theres only one way to fine out fiiiiiight Quote Link to comment Share on other sites More sharing options...
KamaSupra Posted May 20, 2008 Share Posted May 20, 2008 I've got the hi-power 409 on my NA and its pretty loud but doesn't attract the cops. Got a nice beefy sound too! Quote Link to comment Share on other sites More sharing options...
Dazzi Posted May 20, 2008 Author Share Posted May 20, 2008 lol Branners I have a double decat so maybe the Nur Spec RX would be more ideal Quote Link to comment Share on other sites More sharing options...
