I love my new HFCs! The boys at Zoro were again spectacular, and had the whole install done in 2 hours on the nose. This included me testing the HFCs before installing the resonators, to see if the noise level would be okay without them. Even with the J's properly adjusted, it really was too raucus for me without the resonators; however, with them, it's actually quieter inside than it was with my previously improperly adjusted J's, and the throttle response is noticeably improved! The exhaust note is decidedly more metallic now, and lumpier, almost like there's a mild cam in it. I am definitely impressed!
The only downside I can see is that AFM mode is now a bit louder at highway speeds. That can't be helped, though. The other improvements are well worth that sacrifice!
Sounds good! Im going to pull the trigger pretty soon on these. I just had my mid muffler removed and the exhaust is hella loud with the SOLO axlebacks.... so im a bit hesitant for the extra sound volume with the HFC's.
Yeah, I must admit, I'm not sure I could go with anything louder than the Mach Balanced with HFCs. I would definitely recommend the resonators, though: they're not restrictive and they really help calm the exhaust note (at least in the cabin!) under hard throttle.
The stock tune works really well with them, which surprised me: LTFTs, O2 sensors, even cat temperatures were all showing normal, and the throttle pick-up was great. That having been said, I already have my money order mailed to Livernois to see what extra gains may be had .

I ordered a Mach balanced from a supporting vendor and I was sent the Mach shorty balanced. How much louder is the Mach shorty balanced over the Mach balanced? I'm wanting more flow but not a super loud exhaust. I do family road trips and wanted the Mach balanced for the quieter...
