Stock exhaust with HFCs?

I tried a search, I was trying to see if there were any sound clips of the stock exhaust with HFCs? Preferably the AP2, or if anyone can give any input on how the oem exhaust sounds with just HFCs.

it will sound nothing different then stock. i had a 70mm test pipe with stock exhaust and it was exactly the same tone. maybe a little louder if your at wot but barely.

My AP1 with the Asura HFC and stock exhaust and CTSC sounds the same. Quiet which I like.

Mostly the sound is damped by the resonator and not much by the cat.

I have my ap1 with OEM exhaust (including oem res) and just and Invidia test Pipe.

It sounds deeper, but still same stock tone.

Stock exhaust with a testpipe sounds like garbage so I can't imagine this will sound much better.

Cut off the resonator if you want, but HFC or test pipe won't make a real difference in sound. Best bet is aftermarket exhaust with different mufflers and tips.
