tell me what you have and your impressions. I have a 2005 G35 5AT and I'm in the market for headers. Do all headers fit the same, like 350z, G35 Coupe, and G35 Sedan? Thanks for your help.

 

I was going to buy some alphawerks headers off of a coupe owner from this board. The seller never got back to me but I did email the company that makes them and they said the headers for the coupe are interchangeble with our cars. I'm sure its the same for the Z.

 

yes, the headers are all the same. coupe/sedan/g35x/350z, they all fit our cars. if you do some searches you may get lucky and find some dyno results from different brands. i did some hw at one time and found that the borla headers had the lowest gains. alphaworks are nice but were too expensive for me as most headers were. im sorta broke, so i went with the pro-1/topspeed stainless steel headers. they are inexpensive and i was happy with the quality. install cost me twice as much as the price of the headers becasue the awd system on my vehicle gave them a tight spot to work with.

goodluck with your decison
