Considering you have a large cam, your car is being severly choked by running the stock manifolds. I would have done LT's a long time ago if I were you so my vote is the LT's hands down no questions asked.

Absolutely agree with the above. You should have had headers a long time ago.

Which one is it?

And I agree, LONGTUBES first. Then get the gears. Have you had your car tuned for the big cam?

Longtubes are such an incredible mod; they yield great hp to cost results and they make the car sound twice as good. Headers all the way and have fun with that. lol

You are easily losing 20 to 30whp running a cam of that size through stock manifolds (much less, stock heads). What does the rest of your exhaust look like?

I feel you have a lot of power to unlock with the addition of LTs

Yikes. Stock manifolds, stock y-pipe, stock exhaust piping? Definitely ditch all that crap. Your car will be a totally different animal with LTs and a decent cat-back.

What cam are you running exactly?

I believe I would go with gears and 3.73s as recommended above. Then get the lt's next.

cc306 on stock exhaust manifolds?

Get some coated Pacesetters, ORY, and a magnaflow or whatever else catback. Watch your car come alive.
