Got some HFC from Stillen, according to them no "rasp" what so ever but not impressed. If you like the Harley sound mixed with M3 than go for it but really not great. Stillen stated that no "rasp" is heard on a stock veh... WTF! who has a stock veh today??? well i should have gone with FI or Crawford but too late now... or is it? MY 2Cents..

 

so you hate the stillens because of the sound?

can you post a clip?

maybe you should do a reflash...you have quite a bit of breathing mods...are you finding it's pulling timing?

 

thanks for the info... bout to get some for my g.. had kinetix on my Z and they sounded great with my nismo headers and exhaust... got greddy evo2 on my g and no headers... need more sound here!!!

 

I personally like kinetix
