NISMO exhaust and Helix HFC's
 

Anyone running this set up? How's the sound and fit? Thanks in advance!

interested also, bump

I have to ask: Why are you interested? You already have HFC and exhaust. I wait with baited breath...

I have this setup...

The sound is good (if you like aggressive). But I also have a CAI, Spacer and Headers. The Nismo exhaust installed with no issues. The HFCs took a little finessing with the floor board and required a homemade bracket. The sound is definitely louder throughout the entire powerband under normal acceleration. At WOT it sounds like a race car, but I like that, so it works for me. I don't believe HELIX offers the HFCs anymore... I bought them specifically for there build quality and 100cel metal substrates. The HFCs have around 30k on them and still going strong!
