Wow. Pricey. Technosquare charged me $1,500 for G3 intake, header, HFC, exhaust install, ECU remap and before 'N after dyno. The ECU remap and dyno is $750 alone.

My shop said 500-600... sounds about right from everything you guys told me

I just called technosquare and they quoted me 600 for the install of the headers...and another shop quoted 1100 for them here in huntington. SO that is a no brainer..haha :eekdance:

Header Install
 

Mine Stillen Headers just cost a little skin from the forearms, a set of air/fuel sensors and a little attitude to install. Not so bad though. I as well have Stillen HFC, Stillen Gen 3 Intake, Stillen Grounding Wires, Stillen CBE, Stillen ud Pulley / Gates Belt, Stillen Sway Bars, Eibach Springs and have all the taillights smoked out. I love this car.:leghump:

Heh, a pair of A/F sensors for our headers costs more than the average installation charge, unless you've discovered a source other than Nissan :) Very expensive things to destroy, about $400 a piece and unavailable from anyone but Nissan last I heard.
