Budget Muffler Mod

When I went looking for exhaust options for my 2019 Silverado Custom Trail Boss I found plenty of catback exhaust options available, ranging from around $600 to well over $1200, and of course the straight pipe option for around $110. I didn't want a loud exhaust, just something to make it sound better and get rid of the flapper that was killing power. 

 

After some searching and some dyno feedback from Engine Masters I ended up purchasing a 3" offset stainless Cherry Bomb Salute Muffler and 2 stainless clamps for a total of $80 from Summit Racing. 

 

The removal was straight forward, cut the existing muffler out while leaving as much of the factory pipe as possible. The downfall of the stock exhaust is the 2.75" diameter pipe that needs to be stretched to 3" to slip fit the muffler. I bought the Astro Tools pipe stretcher to stretch the pipes and it worked flawlessly, another tool I should have bought years ago. You could take it to a muffler shop to have them do the same thing if you didn't want to buy the tool. 

 

Install is simple, slide the clamps on loose, fit the muffler to the factory pipes, and tighten the clamps. You can save yourself a little money by welding the muffler if you have the capability to weld stainless, again a muffler shop can do this for you. 

 

Overall, sounds near stock at idle and moderate throttle application. At WOT it is noticeable but not wake the neighbors loud. There is no drone but it did increase the cabin noise at highway speeds. The best part is I noticed a huge improvement in throttle response, especially in city driving, and my fuel mileage increased by a solid 1-2mpg. My only regret is not doing this when I bought the truck.

Thank you for your post. Great mod on the exhaust. I had mine done at my go to muffler shop in Minneapolis. "The Wonderful Muffler Man" cut out the flapper valve and welded in a new muffler for $156.00 leaving me a lot of money for a full center console, wheels and tires, step boards etc. I love the sound. This is the first mod I make when I get a new truck!

Don't let the people that spent $1,000 on a cat-back exhaust see this thread, they will get mad that you didn't spend more money to gain absolutely nothing.

...but...but...but...

 

If you don't replace all that welded, stainless steel, mandrel bent factory pipe with new, mandrel bent, 1/4" wider welded pipe then you're just a hack and a fraud and wasting everyone's time!

 

 

Nice work!

 

I attempted to do about the same thing but got trigger happy with the Sawzall and cut the factory pipe off too long.  Whoops.  Still, less than $200 including the trip to the muffler shop to fix my goof and the truck sounds great without any noticeable drone.

 

Notice he used a longer muffler everyone?

I'd need to hear it to believe it.  I have yet to chop my exhaust but if there is a muffler-only mod that won't drone, I'm 100% willing to give it a go

      3.59 Kroger’s in Montgomery Tx. 20 cents higher than most around here. Very unusual. Saturday they were 3.49.

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By KARNUT · Posted

      Starting at 17 running parts for my father’s construction business to haul our equipment. Eventually doing shows, sales and training after purchase. I drove a minimum of 50K miles a year. Half hauling something. After retiring 30K miles a year to the last 2 years 15K miles a year. 2/3rds highway driving. The major contribution to fatigue for me is from anticipation and awareness. I just don’t relax. Too many idiots on the road. There’s two kinds. The group that never leave the left lane tied together afraid to let anyone in doing 80. They’re mostly on weekends. Then the left lane sleepers usually next to a tractor trailer not advancing. Eventually the tractor trailer will drift over the sleeper will wake up. The train moves and the tailgaters who are usually mad as hell. You definitely don’t want to mix with them. The tail wagging bumper puller’s with under powered trucks are holding the tractor trailer up. That bunch are dangerous. I usually pace ahead all that. Unless there’s a gap when I can chill and let the speeders pass. I tried all different types of driving. I stay to the right except to pass, it’s the law that’s getting in forced more now because of road rage. I was so happy when my wife didn’t want to do the camping life. I had enough of pulling for work. The family has a bus and fifth wheel. I haven’t driven either one since retiring. No thanks.

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      Yesterday a suggested youtube video thumbnail caught my attention so I watched through it and it was a bunch of short clips someone gathered together of people pulling trailers, a lot of them were bumper pull holiday trailers and a pickup or suv pulling it. a few fifth wheels as well, some motorhome crashes also. The tail wagging the dog theme was quite evident in numerous self inflicted accidents that took out vehicles around them sometimes in the process as the unit finally swung around and flipped over in the middle of the highway. Or the other classic which literally could be called "I forgot the trailer was back there" in passing another vehicle on a multi lane one way freeway and then cutting back in line before the back of the rv trailer had passed the front of the passed vehicle and often in front of a tractor trailer and that never ended well. Or the wide kick out swing of the rear of a long travel trailer as they have so much overhang behind the axles and the trailer smashes into the side of vehicles in the next lane over ( typically sharp turns in city driving ). It makes one leery for good reason to be near an RV trailer after watching a video like that and be it on the highway, in town, or at a gas station where that rear end comes swinging around due to the fuel station being so cramped and not intended for larger trailers. I wonder how many officers have heard those words though "I forgot it was back there" as they investigate the accident LOL.

      Just because a person can buy a travel trailer or a motorhome doesn't mean they can drive it properly. My observation during my RVing years.
