A low-pressure compressor exit stator assembly for a gas turbine includes a multiple of vanes mounted between a full hoop outer shroud and an inner shroud. The outer shroud and inner shroud are mounted to the intermediate case structure. A seal is located between the outer shroud and a bleed duct structure to accommodate thermal growth mismatch.

What is claimed is: 1. A low pressure compressor exit stator assembly comprising: a full hoop outer shroud which defines a lip about an outer diameter of said full hoop outer shroud; and a seal mounted to said full hoop outer shroud, said seal including an open edge which at least partially surrounds said lip. 2. The low pressure compressor exit stator assembly as recited in claim 1, wherein said seal defines a U-shape in cross section, the open edge of the U-shape at least partially surrounding said lip. 3. The low pressure compressor exit stator assembly as recited in claim 1, wherein said seal defines a V-shape in cross section, the open edge of the V-shape at least partially surrounding said lip. 4. The low pressure compressor exit stator assembly as recited in claim 1, wherein said seal is retained through a retainer which mounts adjacent a closed edge of said seal opposite said open edge. 5. The low pressure compressor exit stator assembly as recited in claim 1, further comprising a multiple of low pressure compressor exit vanes mountable to said full hoop outer shroud, said multiple of low pressure compressor exit vanes received within an uninterrupted portion of said full hoop outer shroud without extending through said full hoop outer shroud. 6. The low pressure compressor exit stator assembly as recited in claim 1, further comprising a multiple of low pressure compressor exit vanes mountable upstream of a transition duct between a low pressure compressor section and a high pressure compressor section of a gas turbine engine. 7. The low pressure compressor exit stator assembly as recited in claim 1, wherein said full hoop outer shroud is uninterrupted. 8. A stator assembly comprising: a full hoop outer shroud; an inner shroud; a multiple of low pressure compressor exit vanes mounted between said full hoop outer shroud and said inner shroud; and a seal mounted to said outer shroud. 9. The stator assembly as recited in claim 8, wherein said full hoop outer shroud is uninterrupted. 10. The stator assembly as recited in claim 8, wherein said full hoop outer shroud is manufactured of aluminum. 11. The stator assembly as recited in claim 8, wherein said inner shroud is manufactured of titanium. 12. The stator assembly as recited in claim 8, wherein said outer shroud is mounted to an intermediate case structure of a gas turbine engine. 13. The staler assembly as recited in claim 8, wherein said multiple of low pressure compressor exit vanes are located upstream of a transition duct between a low pressure compressor section and a high pressure compressor section of a gas turbine engine. 14. The stator assembly as recited in claim 8, wherein said seal is located about an outer diameter of said outer shroud upon a lip which extends from said outer shroud. 15. The stator assembly as recited in claim 8, further comprising a retainer which traps said seal upon a lip which extends from said outer shroud. 16. The stator assembly as recited in claim 8, further comprising a rivet which traps said seal upon a lip which extends from said outer shroud. 17. A gas turbine engine comprising: an intermediate case structure; a bleed duct structure; a full hoop outer shroud mounted to said intermediate case structure; an inner shroud mounted to said intermediate case; a multiple of low pressure compressor exit vanes mounted between said full hoop outer shroud and said inner shroud; and a seal mounted to said full hoop outer shroud, said seal engaged with said bleed duct structure. 18. The gas turbine engine as recited in claim 17, wherein said full hoop outer shroud is uninterrupted. 19. The gas turbine engine as recited in claim 17, wherein said seal seals a low pressure compressor compartment with said intermediate structure within said bleed duct structure. 20. The gas turbine engine as recited in claim 17, wherein said multiple of low pressure compressor exit vanes are located upstream of a transition duct between a low pressure compressor section and a high pressure compressor section of the gas turbine engine.
