I have a top speed pro1 exhaust, which is mid pipe to mufflers . I am adding top speed y pipe, once they have it in stock. I know for a fact that adding just a ypipe with bigger diameter will not really satifisy me with he sound i wanna get, so i m thinking of getting hfc. I heard fi rhfc is the best in market but quite surprisingly i have never seen top speed and fi rhfc combination . does anyone have any ideas, regarding to this combination? Let me know guys. Thanks!

 

I have this EXACT combo. FI rhfc's, M2 Performance y-pipe (identical to TopSpeed), and TopSPeed exhaust. The exhaust sounds good without being too loud. Clean and not raspy. Little drone at low RPM.
