If it's too loud, use ear plugs, or buy a Cadillac.

I have a choice, either louvers or a glass pack. With a high HP motor, you'll be blowing them out in a short time.
If you want the sound to be adjustable for race & street, make or buy the mufflers like "SuperTrap".
"Seems like the ONLY readily available options are "side pipes", kit form, done. Not good enough, gotta have some options".
If these aren't "Good Enough",..........make your own and stop crying about it !
There's always one in the bunch.
I can't make everyone happy, all of the time.
