Josh Posted February 21, 2011 Share Posted February 21, 2011 Have a look on Youtube. There are vids of the hi-power silent on NAs but the only vids of the hi-power are on TTs. Quote Link to comment Share on other sites More sharing options...
Tyson Posted February 21, 2011 Share Posted February 21, 2011 I have a hi power silent on my TT6 and its not that loud, sounds awesome though. Quote Link to comment Share on other sites More sharing options...
Matt _Aero top_ Posted February 21, 2011 Author Share Posted February 21, 2011 It will be going on an NA that's why the middle box is a must Quote Link to comment Share on other sites More sharing options...
Matt _Aero top_ Posted February 21, 2011 Author Share Posted February 21, 2011 So if the silent has no middle box and the plain old hi power has no middle box , whats the difference ? Quote Link to comment Share on other sites More sharing options...
suprab Posted February 21, 2011 Share Posted February 21, 2011 iv been trying to get a middle box for my silent hi power, no success yet. im single turbo and getting grief from the law on its loudness!! Quote Link to comment Share on other sites More sharing options...
L18msy Posted February 21, 2011 Share Posted February 21, 2011 I have a hi power silent on my n/a and i don't have a middle box. It isn't that loud but makes a nice sound. Quote Link to comment Share on other sites More sharing options...
supra_si Posted February 21, 2011 Share Posted February 21, 2011 dont bother with either mate, i had one and lasted 2 years and rotted away, the back pipe is mild steel and then can is stainless... uk weather is horrid to it, if you have the chance get a full stainless with stainless pipes as well then yeh go for it... dont be fooled alot of pipes say stainless exhausts but in fact they are just referring to the can on the end Quote Link to comment Share on other sites More sharing options...
L18msy Posted February 21, 2011 Share Posted February 21, 2011 My centre section was mild steel, got it replaced with stainless so no rot here. Quote Link to comment Share on other sites More sharing options...
Matt _Aero top_ Posted February 21, 2011 Author Share Posted February 21, 2011 i found an old thread and was under the impression the hi powers both had middle boxes in them the only difference being which i have now found out is the hi power being stainless backbox and steel mid pipes and the silent hi power being full stainless .

Matt _Aero top_ Posted February 22, 2011 Author Share Posted February 22, 2011 thinking a whifbitz system would be good value for money when comparing against other full stainless systems . Quote Link to comment Share on other sites More sharing options...
suprab Posted February 22, 2011 Share Posted February 22, 2011 i emailed HKS about it and they said there is no centre box on the silent Hi power Quote Link to comment Share on other sites More sharing options...

Check the thread out . http://www.mkivsupra.net/vbb/showthread.php?152607-NA-Exhaust-Help&highlight=hks+hipower Yea that thread explains it really, Nic even has the pics up! The exhausts are basically the same but the Silent Hi Power is full Stainless Steel but the Hi Power is only a stainless steel back box with mild steel piping Quote Link to comment Share on other sites More sharing options...
Nic Posted February 22, 2011 Share Posted February 22, 2011 Both exhausts are identical in design, the only difference is that the HKS Silent Hi-Power is 100% stainless steel, the HKS Hi-Power is mild steel from the back box forward. Both are rated at 98Db, stock is 87Db. The model for the 2JZ-GTE just has a single back box, the model for the 2JZ-GE has a silencer on the mid pipe. http://www.hks-power.co.jp/products/exhaust/muffler/lineup/img/31019AT005_zu.gif Quote Link to comment Share on other sites More sharing options...

Is the exhaust alride for it? even tho is got the GE engine and not the GTE The HKS Silent Hi-Power for the 2JZ-GE has narrower piping compared to the 2JZ-GTE version - 75mm vs 95mm - it also has a second silencer on the mid pipe. It will fit the TT and will be fine, it'll be a bit quieter than it is on the NA. Quote Link to comment Share on other sites More sharing options...

I would of thought it would be louder Quote Link to comment Share on other sites More sharing options...
