Cam without LT headers.
Hi, Gents I currently own an A6 2012 G.S. I have an A&A blower installed on the car. I was wondering if I should get a blower cam and forego long tube headers.[ Keep the stock headers} Would that work out fine? Anyone with this setup? Thanks.

As everyone said ls7s are a great buy. They are not as good as longtubes but the stock ls3s are very restrictive.
On my grandsport i did ported heads, btr 4 cam, and ported intake manifold. Only made like 435whp which was sad. Swapped to gutted cat ls7s and picked up like 60whp or something. You will need someone to weld up the exhaust but it is easy/cheap and i have had it done on two of my corvettes to avoid paying the big premium for longtubes.

I have a 2006 ls2 the ls7 exhaust manifolds bolted to the engine fine but then I had to change the rest of the exhaust (x pipe and mufflers) to Zo6 stuff. All of that is 3," you want 3" pipes
