matth76 Posted April 13, 2009 Share Posted April 13, 2009 Hi Does anyone have the HKS Hi Power (true dual) twin exit exhaust with titanium tips ( ) or seen one fitted to a 350z? I personally love the loud raspy sound just wondered if anyone had heard and seen it in person and what were your thoughts ... over the top or really nice? Does anyone have a review - are they very good quality and do they fit well? Does anyone know if the bore diametre is larger or the same (2.25") as the stock exhaust (being "true dual" I assume it allows much better flow)? Thanks for any info.

3FIDDYZ Posted April 13, 2009 Share Posted April 13, 2009 Think there is one or 2 people over here with the HKS. Big seller over in the states, great piece of kit, but beware of imatations on the web, there are a few fakes about... Oh and careful with using these if your using hiflow or decats, you may loose power... but with decent or stock cats you should be fine.... What sort of noise you looking for?

Adam@Z1auto.com Posted April 13, 2009 Share Posted April 13, 2009 you will not lose power with any high flow cat or test pipe UK cars require modifications to the diff housing to fit this exhaust Quote Link to comment Share on other sites More sharing options...

There was talk that TD zorsts lost power but guess you have lots of experience in this area Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted April 13, 2009 Share Posted April 13, 2009 As been said lots of cheap replicas available so be careful. I fitted one (replica) to a mates Z last week and as Adam said I had to modify the diff housing. No mod required to the diff housing on the JDM. Alex.

Adam@Z1auto.com Posted April 14, 2009 Share Posted April 14, 2009 no engine on the planet wants backpressure..NA, turbo, or supercharged - backpressure is bad in all cases many people confuse backpressure and exhaust velocity. Do some searches online, there is a wealth of info up there Quote Link to comment Share on other sites More sharing options...
