I'm interested in buying headers for my 04 Z. Several other Z owners have recommended stillen headers but I have also heard good about borla. I will also be installing a hks hi power exhaust. Any thoughts on stillen or borla?

 

Stillen actually makes power...

 

Welcome. Look at the Borla threads from 5 years ago. Very informative.

 

I coulda sworn you will actually lose power with either one of em for a DE???

 

I'm not sure about that, some people i have talked to have found gains with stillen.

 

I recently installed stillen headers on my DE and it made great gains on my butt dyno...mid range and top end I definitely felt a big difference....and now instead of my exhaust being loud my engine is loud now too. I definitely recommend stillen headers to anyone...great design and power...
