Va Beach / Hampton Roads G owners?
when i ordered my stillen HFCs they sent me 08 sedan HFCs and didnt fit... Stillen explained that all the HFCs are the same and the only different was the Flanges. so i got it modified. i had a shop chop the flanges off my OEM cats and welded them on to the Stillen ones... i think they charged me like 60 for the welding, but im sure you could do that yourself since you weld... Good luck!
