It's the Spoon Sports N1, got a really nice sound to it, will have to post a video of the car up sometime on the move so you can hear it.i would also like to know. i like that muffler.
Ye i put the HID's in there last November but to be honest i don't find them any better to drive with as the reflectors in the lenses are quite poor i think.not bad bro. Looks like you got some HIDizzzles. needs to be lowered in the front more IMO.
Interesting you mention the header i had a look on this link which IIRC i found on here which has now really made me unsure on which to buy?!Looks good and you should get a new header, the D15 is probably robbing power from you. Try to find a Z6 one or some cheap ebay one maybe. I like your VTI rims painted white. I have a pair that i have started to paint black but i might change them to white now.
