I've got 323whp/264tq (SAE=315) with stock headers plus Stillen G3/HFC/CBE/UD, According to mtaxelson
http://www.the370z.com/parts-sale-pr...ml#post1466115 He got a bit more torque, probably from the headers.
FI Exhaust dyno's at 3-4 whp more than the Stillen, their LTH/CBE has to be the cleanest through-and-through out there-and it's light. GLWS!
