?? Have I gone to far ?? (E-Cutouts: Pix & Vids)
I'm also wondering if you have stock exhaust (so far) can u just get a Y-pipe and have only 1 e-cutout after the flex parts and have the same effect/tone with less disturbance in the flow?

Racing domestics some years ago, I was bracket racing against a rail dragster. For those unfamiliar with the sport, you basically run as close to a predicted time as you can to win. You never know who will line up next to you, and this was a classic case of that.
With a several second head start (my car being understandibly slower), I was well down the track when the rail car came thundering up behind me. All of a sudden, it felt like the parachute had been pulled.....my car just "layed down" in dragspeak.
A quick datalog review showed 19 degrees of timing being pulled at around the 1000' mark.....about the same time I could hear the other car. My car "heard" the open-header car and triggered the knock sensor from THE OTHER LANE!!!

Very interesting, that rail car must have been booming!
My Review (after one day)
Sounds a little raspy at WOT when the cutouts are closed. But for normal driving (and cutouts closed) it does enhance the stock echaust note - makes it a little deeper. I love it.
Sounds like a f*ing beast when the cutouts are open. Thats all i have to say for now. I dont really plan on actually driving with it open so i dont know how the power gain (or loss at the low end..) is (yet) but ill try it eventually. for now its just another toy to play with

back then, my car only had a 5/16" spacer with a k&n filter. eventually, i got HFCs - but i'll get to that later.
my impressions: overall, this mod was well worth the money to me at the time. i was not looking to get any performance out of this whatsoever. it just sounded cool at the time (which is all i wanted). as it turns out though, and as expected, it felt extremely sluggish when it was open - even during the daily driving conditions i could feel it. i can't comment too much on the top end as i never tracked my car and i'm not one to do push my car on the open roads.
imo, the e-cutout's motor was too slow to be effective. if it was faster, instantaneous, then i think it would be useful to leave it closed to begin with and open it up once you need that top end power. as you can see from the clips, it takes about 3-4 seconds to open/close.
ideally, this mod would work best if it opened quicker and the switch could be mounted on the shift **** or somewhere near it...so that you wouldn't need a third hand to push the button while steering/shifting.
note: this was crazy loud, definately not street legal. with the addition of my HFCs, it got even louder (along with the drone). but it sure as hell sounded mean...people were literally blown away when i went to meets.
