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.

      Injector update

      By iso221 · Posted

      Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

      Injector update

      By CamGTP · Posted

      Why is my question?   Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.   Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

      When a condition becomes a business model.    https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/   Zane posted this in "Latest Articles".    The honest bottom line   Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management.   Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage.   Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land.

      Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks.    Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's.    This is  our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on.
