I drove a 350Z with Alphawerks Stainless Steel Headers - Helix SS Test Pipes - Injen Super SES Cat-Back Exhaust System . Happy with the way it ran:

16. Davidv ----------------------04 Enth 6spd 13.331@105.24mph 1.947 60ft Street

 

the car will need a tune afterwards

be sure you're prepared for the header labor (either DIY or by a shop)

the results will vary by many factors, not the least of which is what year the car is in the first place

 

same here, running all 3 and loving it, TS,OBX,HKS catback. its loud as anything but thats gonna be your only problemo... and some extra power/ loss of traction =]

 

got an 08 coupe and am considering dc sport headers,borla catback and hfc with already r2c intake. hopeing for a good outcome.

 

there are no dc headers for an 07 + car

 

Tomei headers and test pipes with HKS HighPower exhaust. Good tune, no issues, and no rasp.

 

well i need a tune already, ive been planning on getting osiris, and i have the headers already, my wife is going to pay to have them put on while im in guam on deployment, am i going to need a tune right away?

 

It does sound beautiful!
