1. A seal system for a gas turbine engine comprising: an annular seal carrier; andan annular compliant seal mounted around said annular seal carrier, said compliant seal includes a multiple of legs in cross-section,wherein said compliant seal is “E” shaped in cross-section such that the compliant seal has a first surface, a second surface opposite the first surface and three legs extending from the first surface, andwherein said annular compliant seal includes a slot on the second surface to at least partially receive a protrusion on an alignment rib of said annular seal carrier wherein the protrusion is complementary in shape to the slot. 2. The seal system as recited in claim 1, wherein each of said multiple of legs include a distal end thicker than each of said respective multiple of legs. 3. The seal system as recited in claim 1, wherein each of said multiple of legs include a rectilinear distal end thicker than each of said multiple of legs. 4. The seal system as recited in claim 1, wherein said slot is opposite a central leg of said “E”. 5. A gas turbine engine comprising: an outer case;a blocker ring mounted within said outer case;a tab that extends from said blocker ring through said outer case;an annular compliant seal mounted around an annular seal carrier, said compliant seal includes a multiple of legs in cross-section that seal with said outer case and said blocker ring;wherein said compliant seal is “E” shaped in cross-section such that the compliant seal has a first surface, a second surface opposite the first surface and three legs extending from the first surface, andwherein said annular compliant seal includes a slot on the second surface to at least partially receive said tab on an alignment rib of said annular seal carrier wherein the tab is complementary in shape to the slot; andan actuator mounted to said outer case, said actuator directly engaged with said tab. 6. The gas turbine engine as recited in claim 5, wherein said outer case is manufactured of a first material and said blocker ring is manufactured of a second material, said first material different than said second material. 7. The gas turbine engine as recited in claim 5, further comprising a cover plate mounted to said outer case, at least one of said multiple of legs in cross-section seal with said cover plate. 8. The gas turbine engine as recited in claim 7, wherein said tab extends through the sot in said cover plate. 9. The gas turbine engine as recited in claim 5, further comprising a stationary blocker ring mounted to said outer case, said blocker ring movable relative to said stationary blocker ring. 10. The gas turbine engine as recited in claim 5, wherein said blocker ring is mounted within said outer case. 11. The gas turbine engine as recited in claim 5, wherein said outer case at least partially defines a turbine exhaust case. 12. The gas turbine engine as recited in claim 11, wherein said turbine exhaust case at least partially defines an augmentor section of said gas turbine engine.
