TopSpeed + Berk HFC sounds like pure sex... best sounding combo I've ever had.
Stillen with HFC's is so raspy it's embarassing to drive.
Fast Intentions... Be prepared to wait.
Heard nothing but good about Invidia.
I currently have Berk and it's my favorite. Slight rasp at WOT around 4500 rpm... Otherwise sounds great, fitment is better than OEM and the tips are the best looking IMO.
