Top Speed Pro-1 muffler sound

Disregard the video, night is falling and I had to position the camera for the best sound.

First run is in 1st to 6,000 rpm's at 2:55 to 3:05
2nd to 6,500, 3rd to 6,500, 4th to 5,000 at 4:40 to 5:06
Next run is in 1st to 6,500, 2nd to 6,500, 3rd to 6,000 at 5:30 to 5:55
Next is 1st to 6,500 and 2nd to 4,500 7:06 to 7:18
the last minutes are just cruising at 43 mph 9:00 plus

Thanks for sharing the video! I ordered my "bent" Top-Speed muffler on Tuesday and am hoping to see it by the weekend to install. I will just be replacing the factory muffler on my 2.5L but I'm hoping to improve on the sound a bit. I'm thinking this muffler and finally de-snorkeling will be music to my ears!

The high-rev sound clips sound great. How does it sound from 1-40 mph at normal acceleration speed?

I agree with the bit of raspiness down low, but the thing sounds great when the engine's wound up and screaming.

Hope it sounds that good on a 2.5
