Here is better video to audibly demonstrate the low freq rumble of my recently installed Flowmaster Super 50 Series Dual exhaust system.

 

The OEM Flapper was retained (similar to the Borla/GM) system. This is a 6.2.

Finally had the tips moved to rear quarter flush and with a slight stagger.   Sent from my HTC One using Tapatalk

How did you retain the flapper?

cut it off the stock system and reinserted it upstream of the Flowmaster.

Finally got my exhaust on. 2.25" piping from the cats back to a flowmaster 2.5 x-pipe, piped to a flowmaster dual in-out muffler, then piped off passed the tires at a 90.

Well I ordered my Borla XR-1 (15 inch case)! Should be here tomorrow! I might've messed up though, I got the 3.5" in/out... So the exhaust shop might have fun mounting it up. I plan to leave the resonator in place and probably remove the flapper.

Leave both the flapper and the resonator.

From what I've read on here, leaving the resonator will make the exhaust a lot quieter than without no matter what muffler it put in place. I had everything from the muffler back removed on mine and it sounds great. Even though I don't mind the V4 drone, sometime down the line I may have a flapper valve added to the front of the muffler and see how much that helps the drone. I have dual out so that's why I may put it in front of the muffler. I know a couple people on here did that.

I regret removing mine.

The only reason I didn't say anything to them about it when I had the exhaust done was because honestly I hadn't had the truck that long and didn't even know there was a flapper valve there to help with the V4 drone. I thought nothing of it since with factory exhaust you can't tell what mode it's in unless you look at the dash.

My wife drove my truck yesterday, and I was standing at the front door watching her drive up the street (she has learned to use the throttle well!).

 

I gotta tell ya: That 14" Magnaflow sounds BadAss!

 

You get used to the sound inside the truck, but from outside, sounds MUCH better, more aggressive.

 

Just confirmed my choice of the Magnaflow. Glad I did it. :P

Love mine, but the drone isn't something I can tolerate for long.

gonna need a vid for proof, and did you just mount a muffler and tip?

I'm one of the rare breed that love the drone....

I've made a video, but it's not a very good one, non-conclusive. I'm planning to make another one.

 

I did the 14" Magnaflow with flapper and resonator delete, not a cat-back. I'll post a new video/audio clip in a day or two.

I think I've decided I'm going with an 18" or maybe 14" magnaflow or the flow master super 44. I have about a 30 minute commute on the interstate to and from work. If the drone becomes an annoyance and something that my music won't tune it out, is the flapper easily added back in post-install? I like hearing the exhaust rumble and am looking for something loud/mean and aggressive. I don't know what the v4 will sound like in person as I've never had a vehicle with some type of AFM. The vids on here are nice, but I'm sure they are like anything else, they are a little different in person. I've got the 5.3 so I want to hear the 5.3 lol.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      By davester · Posted

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
