Finally got some time to do this to my RST today. LOVE the difference it makes. It’s the perfect noise level for me. The depth of the noise and the growl are definitely noticeable. I can even feel the growl on the gas pedal when I floor it. ????

 

I opted to just use sheet metal to cover the screens, as I wanted the option to remove them cleanly if I ever wanted to. 

 

I’ll try to upload some videos I took shortly.

If we could hand out trophies on the internet, we would most certainly give you one.

So then don’t do it and be on your merry way. Some people like it some don’t. It does change the tone for the better IMO. Carry on Sent from my iPhone using Tapatalk

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! 
For the flapper valve yes you need a rectangular piece of metal between the two clamps to hold the flapper open.

Here’s a video with the rear window open. You can easily hear the difference. [emoji16][emoji1377]
 
 
The oh yeah made the video. Thanks for a good laugh. Glad you like the sound. Your gas mileage will suffer now that you will be flooring it all the time.

Lol, I was thinking about that earlier today... now that I get more reaction from the truck for standing on the gas, I’m going to be driving like I did in high school again. ??

I just towed my travel trailer 600 miles up into the Adirondack mtns. I removed all the clamps before I left so I wouldn't hear the exhaust echoing off the trailer the entire way. Need to put all the clamps back on now that I am done towing for a month.

This is why I love this little mod. Cheap, and SO easy to remove, then put back into place whenever you want.

Ok sweet.  I got it done today!  I'm not really mechanical but your pics and description made it pretty easy.  Some of the clamps I used were too big but good enough.  

 

I took a video of the sound but darn AC unit sounds super loud.  Will have to take a better video later.

I don't think you got the flapper valve clamp on there correct. The outer clamp should be on the knob not the inner spring. Also make sure you rotated the flapper knob the correct way. It should get harder as the spring compresses that is how you know it is rotated in the right direction.

At least that is the way I did it. With your clamp in the middle it might mess up the spring or come loose?

Ok, thanks for the heads up.  I'll move it over.  And yeah in one direction it had resistance and the other it didn't.  I rotated so it had resistance.  I think I'm going to go with a black widow mufflers and have the flapper removed.

I have some left over dryer duct in my basement. Looks like I have a head start and will be doing this tomorrow. Excited to hear the results

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.

I know muffler tape will work wasn't sure about HVAC as muffler tape is high heat rated but if it's been on there 2k miles should be good as the pipe doesn't get as hot towards the rear. May be more of a mess trying to remove the tape though than the clamp method if you ever needed.

      Mangoal or FitcamX OEM Dashcam?

      Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge.

      Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
