Anyone Interested in After Market Exhaust Discs

What I was looking for in doing this was cutting down the Jake Brake sound more then toning down the sound level. As S197 said just a small difference in size makes a big difference in the sound. I made these in 1/8 size increments but I would bet that you could hear a distinct sound difference in 1/16 size differences.
Give them a try but leave them in for a few days, it is hard to get an idea after only a day or two, especially since that is a 1/4 inch.

I am going to try the GT500 axlebacks and reinstall the 3/4" restrictors. Then I will see how my "rafdo" sounds. (Stupid iPhone & fat fingers)

I've got 1/2, 5/8, and 3/4" plates.
Put the 3/4 in, and haven't found a reason to take them out yet.
I'll most likely do it after I return from Sturgis Mustang Rally, and give the other sizes a try.
Cruising down the interstate is very reasonable. The harder the acceleration, the more the sound picks up.
Overall a great product, and Scott mailed them out fast.

I have 1/2, 3/4, and 7/8. I'd start with 3/4 or 7/8. The 1/2 are nice but moving up to the larger sizes gives the car a nice growl without being too loud. I'm currently using the 7/8 and they are fine around town and just a touch loud while talking on my phone at fwy speed.

Scott, I took my discs out last April and really like the exhaust note. Been thinking of putting in something other than the full open pipes I have now but not sure how it may sound with some restriction. Has a "most popular sounding disc" set been decided by those that have bought them? Thanks for any feedback.

Charlie, I started with 1/2" and moved to 7/8" and like it a lot. It's a touch loud while talking on my cell at fwy speeds but other than that it sounds fantastic. I don't want mine any louder and I believe Scott also runs the 7/8".

It is a personal preference. I tried with the discs removed & didn't run that very long. Opened mine to 1/2", still too quite, then to 3/4" & it suits me well.
Considering the GT-500 mufflers as well, but mainly for appearance, as I don't like the 'double' piped tips that come stock on the Boss.

I'm now considering redoing another set of factory quads with the factory resonators either completely removed or changed to a larger size. The quad pipes neck down to 13/16" approximately mid-pipe. That would allow the QTP valves to really make a difference.
I thought that the blown 5.4 would have had fairly substantial flow as well as a bit more growl via the quad pipe exit point but it doesn't. Both engines use similar sized cats with a similar location of their respective engine. Maybe the Coyote has a larger tone for some other reason?
As for the Boss' mufflers, I noticed the "pipe within a pipe" instantly. It looks like Ford simply slipped their fart pipe tip over the stock pipe. Look closely and you can see that the weld for the tip (the weld closest to you) doesn't burn through.
Just cut the tip off at the weld (fart pipe to stock pipe), drive out the smaller diameter pipe, and then weld it back on. If you aren't equipped to do it at home just unbolt each one and drop them off at your favorite muffler shop and have them do it.
