Header's or Cam? Help me out 11 second guys
I have a Vig3600, catback, 3.73's and a few free induction mods. I want to eventually go with a cam but I have been told to go headers first. I pull consistent 1.68 60's but the car feels like it loses some at the top with the big Vig. I want to keep the #7 pump because I eventually want to go fast!!!
What do I do? Headers I'm sure will help out some but maybe not the amount I hope for.
BTW that 12.6 was on the limiter at the 2-3 shift.
Any help would be appreciated.

I’m putting a B1 in early next month but I have yet to choose headers, so will see just how far the stock manifolds with an ORY and a good catback can take. I’d think there should still be something to gain. The stock manifolds on these cars don’t look nearly as bad as the old LT1 and L98 ones did...
You may need programming to get the most out of a cam and not have SES light issues. A 212/218 115 cam rarely needs programming in an A4.
Jake99SS on here was running a T1 through stock manifolds and said the gains were still nice above 3500rpm to redline. I think he still had stock cats too <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
As a bolt-on car with a Vig 2800 I ran 12.43 @ 108 MPH with stock manifolds.
I then added a T1 cam, in nearly identical conditons I went a 12.11 @ 111 MPH.
Then with some fiddling on my launch and pro-stars on the front, I ran an 11.98 @ 112.64 MPH, still with stock manifolds.
So, I gained 3 tenths with just a cam change. With a cam change and skinnies I improved .45 seconds and 4 MPH. Not bad IMO.
I just recently upgraded to a bigger Yank and Macs. We will see what the improvements are, I am 'hoping' for 11.6s.
<strong>Ok peoples. Solid track results coming at you....

Lid, FTRA, and a Cutout.
should get you low 12's @ 110mph or so.
