If you install them and dyno it. You would be the first.

 

How does a Stillen Headers + Resonated FI test Pipe + FI Intimadator Exhaust set up sound along with a tune and ecu reflash? Woudl that work well?

 

Nismo. sounds great with stock catback. cops wont look at it either lol

 

Bump. Anyone dyno any of these headers yet?

 

Dont think so. wish i would have done a before and after but my schedule wont allow a dyno day..lol

 

Would a Tomei Expreme from a 2003 G35 Coupe work in a 2004 Sedan (auto)? Does anybody know?


Thanks!

 

has anyone had problems installing the headers? when they were going to put mine on the studs were too long apparently and told me that i need new screws... mine are nismo headers from 350z

 

Xerd long tube headers!

 

i have DC's and i love them. only paid $300 for install, plus they're CARB legal. the design's gotta be pretty good considering the HR motors later got a very similar designed OEM header.

 

Got the TopSpeed headers a long time ago. Before I added the Megan test pipes, I dyno'd at Stillen with pullies, fly wheel, CAI and Kinetix plenum... at 257.8whp. Not too bad and I had a friend that charged a low price to install the headers way back when I bought them.

Later,

These headers are 50 state legal with the CARB exception number stamped on them?

 

Yep, CARB numbers and all

 

Hmm, now that is cool. I could never tell by the pictures if the CARB number was on the header. The way I understand it is if it is not on the part itself, it wont pass visual. Now, where did you get the headers, and where did you get them installed for $300?!

 

If you have a VQ35DE go with OEM HR headers and HR HFC or test pipes. I have that setup in my car and can tell you the outlet diameter of the HR is bigger and it is a WAY better design when compared to the DE headers.

 

I think that i am going to change out my strup headers and berk hfcs for longtubes this spring. Maybe i willl do a quick write up on a header install so drivers can see what all takes place during the install...
