elmarko Posted September 20, 2010 Share Posted September 20, 2010 Given the amounts members have clearly invested in their vehicles I'm a little surprised there has been so little discussion on header installs here in Oz. From what I read on Club Lexus, headers deliver by far the best 'HP gain' bang for your buck and that should mean something to IS250 owners (obviously 2nd gen IS owners here in Oz). I'm sure I remember at least one ALOC member having Mazzuri headers installed but understand these are no longer being manufactured (though possibly available 2nd hand). Posts on Club Lexus indicate a number of companies are currently manufacturing systems for the IS250 - some of these can currently be purchased on eBay (eg. Megan) but PPE ceramic headers from PPE Engineering out of the US have recently caught my eye. Suffice to say I am keen to see if we can open up the channels a bit on this topic. I would be really interested to hear from those who have headers currently installed on their IS250 and those who have done some research on the topic. Particularly interested in the following: * Cost/degree of difficulty to install - how many 'shops' could have a crack at this locally. * Performance improvements - before and after dynos would be nice but seat of your pants accounts also very welcome * Any negatives ie. significantly increased NVH, engine management warning lights * Views/Experineces on how this mod affects your warranty With the AUD currently so strong, now might be the right time for us to look at a group buy of the best hardware (PPE or other) out of the US if enough were keen. Anyway, looking forward to your replies. Quote Link to comment Share on other sites More sharing options...
