For me, and perhaps others, this before-and-after would be interesting, because it best represents the potential gain from where we are, to where we "could be" with the spend on the headers.

Begin: A car that already has a cat-back, cold air intake, high flow cats (or test pipes), and an optimized tune

After (1): Remove stock manifolds and tp/hfc, replace with headers. Re-tune for the headers, preferably same day/dyno/conditions (I know the installs are a PITA)

After (2): Do the above, but install a catted y-pipe, for those of us that have to retain cats for emissions or racing rules reasons (SCCA Street Touring where I run)

The reason I didn't pull the trigger on a header is I haven't seen a proper before/after done yet - one where the contribution of just the header can be observed, with all other variables properly controlled.

Echo echo echo haha jk

This car has intake, a cat back, stock cats and no tune. We are more interested in the number the VR Tune puts out since this will be our test car. PPE has documented the hp gains on their product already so we will not be testing the headers on their own.

What date are you looking to do this?

Do you have a pic up the end?

Customer is dropping the car off Jan 30th. We will start working on it Monday Feb 2nd.:happydance:

They are back in the box out in the shop...are you asking me for a picture of the flange or??

And so it begins
 

Had a cancellation and the black cherry 370Z was just dropped off. We are going to get started on the baseline dyno run first thing Monday morning.

I was out of the office when he got the springs and Weds SA15R's put on and I have to say it looks great!

Laughing at all the out of towners here for the Golf Tournament and Super Bowl who thought they were going to have great weather. It started raining yesterday and will continue through Saturday.

Update
 

Our donor 2010 370Z with the 6 speed MT, Stillen Catback and K&N Typhoon Intake did the baseline dyno run today. We will be installing the tune tomorrow and then another dyno run. From there we will start on the PPE Headers and do another dyno run. Getting him some new 305-30-19's for the rears while it's here. We will shoot more pics and video and post the results soon!

VRTuned Numbers Are Up!

There's going to be a massive increase since he has stock cats. Install test pipes first.

^^ do you have anything else going on in your life besides bashing every thread from another vendor?

Asking questions, giving advice and saying what others are saying and thinkings not bashing. If they are testing we are curious of all tests. Not just one. I did several tests and still doing some on my product. We are looking for something different here, not something old. My bad for wanting real info, least I'm not alone.

I'm a customer too! I want to know what $1200 buys me and everyone else. Catless eBay tests pipes are $100ish, these are $1300 I'm sure. What does $1200 get you power wise over a stock header and no cats? It's a fair question to ask and want to see!

Have to be premium to see?
