elusive mufflers?

I went with the Spintech sportsmans just for the reason you mentioned. They flow literally the same as an open exhaust. Personally, I love the sound- they are my "go to" muffler. Dont know what type your buddy has on his car, but I would recommend you look into them a bit more.

Here is a link to a video of my old Cuda.

Go to 1 min: 45 sec to go past the fluff to the engine start. I have a few other videos of the exhaust at idle on my channel as well.


Heres one at the strip...
