Here is the after on my truck with flapper open and all screens covered. I think it sounds louder in person. Cold start probably 60 degrees out after sitting all night.

Here is the video from this morning after covering up all 6 screens with unmodified flapper valve. Plan to do a 3rd video of course lol First i had used 2 clamps per screen then went back and looked at the above pics and just did one as I had ran out of clamps lol...one seems to be good enough.

I didnt really notice a difference. You be the judge. This afternoon I will work on the flapper valve. Cutting off the valve completely would probably give best results as this 19s have a 1/4 of the pipe covered after opening up the valve...based on a pic from another thread I read on. However I dont want to cut into it...for now.

Here is the final one. With the flapper clamped open and the screens covered.

A buddy at work just bought a trail boss. We both started them up in the parking lot. Hearing them run side by side, mine is Definitely much louder and has a deeper tone to it with flapper open and screens covered. Especially if you give it some gas.

I think the difference is much more noticeable outside the truck.

After a week or so, I am still happy my $20 investment.

I agree! Even though i have the duratracs i can hear it now at low speeds. Or when cruising out of a parking lot. I am content with the results.

Yeah I agree when I started it after sitting for 4 days I was like nevermind it is actually louder.

Man, I think I’m gonna do this. I’m not brave enough to cut the muffler out, as I don’t think I would like it *that* loud. This sounds like just my level. 

 

Thanks for the videos, y’all!

I imagine I could just use exhaust tape instead of the sheet metal and clamps?

I started my dad's 19 ram 5.7 hemi and then my 5.3 with the covered resonators and flapper clamped open and the 5.3 was way louder.

I used Air Conditioning Aluminum Foil Duct Tape. I used to be in the A/C business and had some in the garage. You can get it on Amazon or at Home Depot.

 

It has been on the exhaust for 2,000 miles and holding up well.

You could use beer cans probably but I just grabbed a piece of galvanized sheet metal from the HVAC ductwork section at home Depot. It was maybe 2ft x 3 ft cost $7. It was the smallest piece they had that was flat.

I don't remember what size clamps I used for the flapper as I had a few of those on hand. Just measure the diameter of the round knob on the flapper and add a half inch to get the clamp size. I got a flat galvanized rectangular bracket from the hardware section to go between the two clamps on the flapper.

First of all thanks for these posts.  This will hold me over for now without spending much money.  Is the rectangular bracket Needed?  How does this work? Sorry I'm not very mechanical lol.  If it's needed I want to make sure I get the right part.  Any tips are much appreciated!
