Is not the same. Not all V8s sound the same and also different exhaust will provide different frequency notes. People have different hearing needs or sound perception, etc.. With the tool you can pinpoint the freq that you want to filer or tame.
It is the same from a V8 standpoint... however Different cars/exhaust designs either accentuate, or cover up the nasty drone frequencies. The raw frequencies at a given rpm are identical though.
Yes it is. Despite what it sounds like to our ear, there are explosions happening at 100-200 times a second (in the cruising speed range) that create discrete sounds. The firing frequency that these occur at is what you tune the Helmholtz/Quarter wave resonator to. Different exhausts have different tones because they use various forms of wave cancellation/interference or absorption to modify what frequencies are audible and at what amplitudes. Please research Helmholtz resonator.
Where did you order from? I'm looking into this for mine.
Total length including the bend on the centerline of the pipe. That summit part I linked is 33" long total, so 8" off the long side. The bend is another 12" on top of the straight lengths.
Here is another site that you can get them from if your local exhaust shop won't/can't make them. These dont have 180s in them.
If you understand the science the 180° actually attributes to covering a broader range of frequencies. The idiots that say the straighter the better....:headbonk:
P.S. those are NOT stainless. highly recommend you spend a little more $$$
