does anyone have a video with the foil delete showing how it sounds, or just the 6637? i just ordered a 6637 kit, and am wondering what it is going to sound like
My stock struck other than what is listed in my sig. I don't notice any noise except- while taking off from a dead stop, a moderate take off and when it drops in OD i hear this Whoosh, for a second. Sounds like a air cleaner fart. That is it.. I was afraid i would get some sort of drone or noisy howl. But nothing.. The foil delete, I just noticed a slight,slight bit more turbo whistle. - Now when i too out my muffler. Everything changed with noise. More of everything.. lol.
you want to hear noise? Take out your muffler and on a cold morning the exhaust valve shuts to help warm up. That is noise.. And worst yet and you want to wake up the neighbor hood? Exhaust valve shuts and a few seconds later the High Idle kicks in.. WOW.. I almost don't like it.. Probably can hear it from the Moon ! lol..
i know the sound of the jet, its amazing, especially in winter up here, when it's -40 with the wind bowing it is really loud, or just -30 calm, you can here it a half mile away. And i don't have my exhaust off yet.
