I love the loud flowmaster 10 sound but might piss my wife off. Would leaving the flapper and resonator on a muffler swap help with the v4 chopper and also tame the flowmaster super 10 a bit? Anyone tried that on a 5.3L?

My 10 SI/SO no flapper or resonator is very tame and in my opinion V4 drone really isn't bad. For me the 10 wasn't as loud as I thought it was going to be. These trucks are pretty quiet. I wouldn't worry bout making the mrs upset.

What about leaving the flapper on? Why not if it helps with v4 chopper?

IMO the V4 doesn't sound bad. But the flapper should help with that if you install it. If you don't like it you could always hose clamp it open afterwards.

I have the super 10 also and find it pretty tame. are there any louder mufflers?

Not that I'm aware of. Maybe CherryBomb Extreme but its the same design as the Super 10. I honestly dunno.

I have the super 44 with res delete and flapper is on but clamped open. Kinda wish I would have gotten something slightly louder. Also have 3rd cat as well

 

Another thing is my grandmother who hates loud trucks and drone loves my truck,

 

The flapper design

Notmal (quiet idle and cursing, will get slight rush of wind noise when reving it.)

 

Valve clamped open, louder idle, and slightly louder in V4 but still very tame sounding no noise when reving only sound of a happy v8

 

Next goal is to see res only with flapper.

 

Also to clamp flapper turn counter clockwise and find a bolt that fits in that spot.

To answer your original question... I think leaving the flapper and resonator on the FM 10 would quiet the V4 chop and cabin drone, and still leave the exhaust sounding pretty aggressive.

 

I have the 10, with no flapper and no rez and it sounds really good. Personally, not loud enough for me.

 

I'm pretty lucky. My wife likes LOUD exhaust. :dunno:

 

If I were to put headers on it, I'm sure she wouldn't object! :thumbs::thumbs::thumbs:

      GM discontinuing interior parts on a 5YO vehicle??

      If one can't be found, a good automotive upholstery shop should be able to replace/sew in a new panel where the damage is on the old cover. It might not be the cheapest option..

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Does your dealer charge you for the tire rotation on top of the oil change price ?. I haven't had any service work done at my dealer yet other than when I brought it back soon after owning it to have the front end aligned to correct the steering wheel being off center a bit. Oh they called me at least twice hounding me to bring it in for an oil change and pushing a 300.00 package of oil change and tire rotation and whatever other quick simplistic checks they would do. Only going off of what a friend gets charged for his half ton for the basic oil change and its the same amount of oil as the L8T holds, it was about 150.00. Once one buys a set of tires from most shops these days or so I believe, they will do free tire rotations and some do free tire balancing as well as free tire repairs.    Certainly doing a tire rotation is no five minute job, and definitely not at home but because I run a set of winter tires on their own wheels, I swap them at home and its a one tire at a time deal because of the tire season swap although I jack up the rear and do it and drop it back down and then raise the front and do them and coordinate the tire rotation into that process for both sets of tires. I am using a floor jack though and if I need to raise both ends at once I use a couple sets of jack stands to have all four tires off the ground. I use either an air impact or battery impact and have electric impact as well so no shortage there of easy methods to spin the lug nuts, and then retorquing the lug nuts. None of it goes quick though but my wages are cheap though ... zero. I live an hour out of town, its easier just to do things like that myself than waste a bunch of time in town and having to make an appointment and probably a special trip and sit there at the tire shop waiting for them to get my vehicle in and get it done and not screw something up in the process.

      Clunk when coming to a stop... driveshaft/slip yoke? Mechanic couldn't recreate it

      By mrbflat · Posted

      I do have the 8 speed.  Interestingly enough, after driving my truck for the past 2 days now, I have not had the clunking issue at all!  I am beginning to think it may have been suspension/leaf spring related, and somehow when the shop put my truck on the lift to do their initial inspection, it relieved some built up tension/pressure that was causing my problem.  I swear it felt I was a bull rider on a bucking bull the way the truck would almost rock back and forth slightly before the big thud/clunk when coming to a stop.  I am hoping I got lucky here and it's gone for good.

      Bring it to discount tire. They do free rotations even if you didn’t buy your tires there. I didn’t believe it until I tried and they did. You can tip the employee if you would like

      Best part of this video is how it resets expectations. Wonderfully done piece. It also made clear a few points I've made from day one. Detergent oils DO NOT KEEP A MOTOR CLEAN at the recommended or longer change intervals. They just get dirty slower than a non-detergent oil and there isn't spits difference between them on this point if they carry the DEXOS license. Great thing about the license that gets missed is it assures CONFORMITY even it that means a low bar.    One thing he did not talk about that I paused on an magnified was the condition of the oil ring separator. Besides a stuck ring a plugged separator and land drain back is huge when it comes control. We see in short order improvement in control IF that is the problem.    Another item I took exception to and he did not make plain was the condition of the timing chest and under valve cover having something to do with indicating piston cleanliness. Schaeffer's Oil makes that same omission in their million mile Ford video. I'm guessing he has never torn down a Red Line HP, AMSOIL SS motor that has been on that diet from the get. What he showed in the video was a good deal of varnish. Something totally absent in Peppers 165K cover off look. I smiled because he did his at the same milage.    He also makes the mistake of assuming oil temperatures in the pan are the temperature all over the motor even though he makes note of the piston being the hottest part of the engine. that baffled me a bit.    I can tell you from personal experience and witnessing teardowns of family motors that even oils of the 1960's would keep them squeaky clean when OCI's were 1500 to 2000 miles without exception. At 3K and above you get what he experienced and the longer you leave it the quicker to gets to the junkyard.    I think his is missing a opportunity not tearing it down again when he's done killing it. Time would be his only cost.
