if you have an exhaust with removable dbkiller, just remove it, and go out and test it. The silencer oem has a bigger hole, and the note is thicker still… .but it points directly to the turn signal, but in a simple test it does not represent a danger of cooking it.
On a wr450 I had, I released the exhaust, but the note was not as thick as on the S10.
doesn't sound like a V-engine either, because the 270-degree crankshaft doesn't make each explosion so noticeable…. The best I can contribute is that it is “only” heard at the torque revolutions… when you're cruising, it's minimally above the original sound. "Backfires", yes ... they appear, but they are soft explosions that do not become "explosions" ... and in certain situations of "reductions". the best I can contribute is having traveled alongside a 1290 with akrapovic… and crossing at 140 km / h… my S10 only emitted a sound that did not bother due to the exhaust… .and the 1290, disturbed the sound going to the even and going backwards. I asked the 1290 driver if he felt "my exhaust" and he answered that no, only when accelerating
the part of the “resonance box” is not modified, and it continues to fulfill the task of preventing the high notes from coming out behind, by eliminating the dbkiller, it increases the sound, but not the high notes that are neutralized inside the box resonance. It is not the same as removing the dbkiller on a perforated inner tube type silencer… .in this case, when removing the dbkiller, it lets all the exhaust notes pass through the back, including those notes that are “annoying” to the ears.
