I'm currently running a Flowmaster 40 singe in dual out with a DMH cutout. However, I got a decent deal online so I am going to be chopping all that off and installing a Corsa DB Series muffler single in/single out followed by a 3" In/Out Magnaflow Y-Pipe into 3" piping coming out of 5" tips. I'm coming from a restrictive flowmaster muffler that was welded on using 2 1/4 piping. So the truck should not only sound better but breathe better. I also plan on getting some ARH long tubes with high flow cats later on. Can't wait to get everything on!

I'm switching now... MBRP is junk ... it just wants to rot away. Being replaced now with a Borla ATAK that splits to duals exiting under the bumper.

Just got my truck back from the muffler shop.

 

Deleted the muffler and replaced with a 3in pipe. Resonator and Flapper left in place with flapper clamped open.

 

 

First impression - The sound is perfect. I watched numerous videos on here and I will say it (like it's been said on here many times) sounds much better in person.

 

$50 = no brainer.

Now that you've had this set-up for about a year, what are you thoughts? Still like it? Any problems?

Is there any reason you chose to clamp the flapper open?

Still sounds great. Got a complement on it yesterday actually. I believe the original thought behind the flapper was to limit the helicopter effect. Seems to have worked.

I'll most likely be going this route.

Thanks Ctay,

And for you and others that have simply just deleted the muffler, did you notice any change in performance? Good, bad, or the same?

Also, does anyone see any potential problem with this muffler delete set-up in the long term?

So your flapper has been clamped open ever since? What does it sound like in V-4?

I can't decide what muffler I wanna get. I had the Flowmaster Super 10 dumper after the rear axle with a 5" tip on my '07 5.3 old truck. It sounded great, nothing too loud. A solid deep tone. This time around I'm thinking either Borla or Magnaflow.

Still on the fence myself for my 6.2L rig - found this info yesterday - leaning towards leaving the flapper and resonator and doing a muffler swap for the Flowmaster Big Block 50..... which would be very similar to the 70 featured here:

Yes, open ever since. About the only thing I've noticed was it kicks out of v-4 a little sooner if that makes sense. I don't really notice v-4 mode because I only see that happening when I'm coming to a stop/coasting. Under load it kicks out too quickly to notice. For me, I have to really try to baby the gas pedal to keep it in v-4 while cruising. Probably worth noting that I rarely do the speed limit lol... These 6.2's are like old-school two-stroke dirtbikes... they like to get where they're going quickly.

      I was the GM of a Lincoln Mercury dealership back in the 80's. The service lot was always full with "broken" ones. Plenty of transmissions, power windows and a/c repairs. The only one I'd consider owning would be the Marauder at this point and it certainly wouldn't be a daily driver.  My 2025 GMC Sierra 1500 Denali Ultimate is my "Lincoln Town Car" in my retirement. I want all the "stuff". Big infotainment screens, one touch power windows, Supercruise (I won't buy another vehicle without it), hands free pretty much everything. I'm going to swap my current truck for a 2027 Yukon Denali Ultimate so I can have the air suspension and surround vision recording along with all the other "stuff".

      The Denali Ultimate's grille is tinted, but the "regular' Denali has a bright chrome grille like the current models.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍
