Aftermarket muffler

does anyone hve experience replacing their stock muffler with something like a flowmaster? Did you experience any problems with how the truck ran after installing it? I was just about to order a flowmaster 50 series but after watching https://youtu.be/1y9StlQZuFE scottys new video i’m having second thoughts.

 

I had a Flow Master 50 on mine for a while. It was great around town and loved the sound but on the hiway was a different story. Since it downshifts so much the drone was not for me. Ive since gone nack to stock. Also there was no increase in MPG or power, sound only. You will not experience any problems other than the drone and that is subjective anyway. By the way, Scotty is annoying as fuck!

 

You wont get any power or mpg gains, or at least nothing noticable. If you like the sound of a louder exhaust, then go for it. I have a borla muffler because I like the sound it produces.

 

All my driving is city anyway and i’m not looking for increased hp or MPG. I just want to make sure doing this won’t decrease mpg or power. And I especially don’t want it to make my engine run like crap. I trust TW more than scotty so if yall say it’s fine i’m going for it

 

I put a cat-back system on my 2.7 auto, it was ok locally, but rather loud. I did a two hundred mile freeway trip with a lot of big hills, the constant shifting of the auto caused me to put the stock system back on. That and I lost a lot of bottom end torque. If I had a stick shift it would likely still be on the truck. So, if I were you I would not do it!

 

Scotty is an idiot... i cant even watch this video.

About 5yrs ago i tried to explain the mistake of throwing hids in a celica with oem halogen based reflector housings. He lost his shit and blew up in the comments section of the video. He just didnt understand an arc and a filament are different creatures.
Just now as i searched for it, i see many others tried to explain the same thing too. Heres the video that confirmed he is an idiot.

That said, ive had a flowmaster original 40, and currently have a super44 in 3" variety.
Both had a tendency to drone at highway speeds, but i do have a v6 so im not sure how it affects 4 bangers.

Ive done alot of work to fine tune my exhaust over the years and have minor drone and no rasp, but again its a v6 so i wont get into details as it most likely wont help u.

 

I like the sound of my Flowmaster 40 around town. I can’t hear the drone at highway speeds over my tires anyway.

I just turn up the radio and most all other sounds go away

I have a v6 but I’m sure the radio would work on a 4banger too

 

Scotty needs a muffler on his talk-hole.

 

Agreed

If a noisy exhaust is valuable to you, go for it, it's your money.

I have better things to do with my money than replacing something that still works perfectly.

 

Scotty is an annoying pissant....i dont know why anyone gives him a second thought.

changing your muffler isnt going to effect anything other than the sound.....if you want a louder, slightly more aggressive sound, by all means, swap it out.....however, just keep in mind, its a 4 cylinder, so its going to sound like a modded Subbie or Honda....its not going to sound like a V8.

what CAN effect your performance is changing the exhaust pipe diameter.......if you go too large, you can stagnate the exhaust flow, causing poorer performance......for our motors, about a 2" diameter pipe is perfect.

but just swapping the muffler isnt going to effect that.

 

LOL Scotty Kilmer is hilarious to watch.

His neighbors must think he's a freak. He's always outside screaming at his video camera.

 

The best muffler I have ever heard on a 2.7 is the TRD muffler from the V6 trucks that someone purchased pretty cheap used and had a muffler shop weld it in.

I can't remember if he kept the resonator before the muffler but I want to say they deleted it.

Sounded SO good!!

 

A simple muffler replacement with a 50 Series Flowmaster will add some tone to your vehicle and WILL NOT cause a loss of power when correctly installed. With the addition of one of our Universal Replacement Mufflers, tuning is not necessary. If you're installing "power adders" such as turbo's, superchargers and in some cases even performance-based headers then a proper tuning can help to squeeze some extra HP's by correcting fuel trim through the use of a tune. With a muffler replacement, you are getting a different exhaust note and any difference in the volume of air that the vehicle is consuming is controlled by the vehicles ECU (main computer). Our Cat-back systems include larger diameter piping which helps the application to exhale easier and even with the larger piping that our Exhaust Systems provide no tune is needed, the ECU handles it.

How did my comment get quoted in your post?

 

Not exactly, so maybe a little clarification is in order...my comment was in response to the YouTube video that was posted and the question that was asked. The information in the video is incorrect and a simple muffler replacement will not affect ANY of the "issues" that were discussed (if properly installed). I then attempted to compare how replacing a muffler versus replacing the exhaust system itself with a performance-oriented Cat-back will affect the vehicles performance and its many computer controlled systems.

When the factory muffler is replaced with a performance version but still using the stock exhaust piping (which in most cases is small piping with pressure bends) there will be an increase in sound but an increase in HP's or TQ will be minimal. The computer controlled systems in the vehicle will not be affected.

Whereas, the addition of one of our Cat-back systems will include larger (over stock) mandrel bent pipe along with one of our performance mufflers. The larger piping along with a free-flowing muffler allow the engine to exhale better, thus freeing up horsepower. When large power-adders are installed (turbo or supercharging, performance headers, CAI's in addition to a free-flowing exhaust) then a tune should be performed to gain the best performance numbers and lessen the chance for catastrophic failure of a major component

We spend a great deal of time and money researching and testing every performance product that we sell. We also dyno test nearly every product and include the results of those tests on our website. I have included a dyno chart below of a bone stock 2014 V6 Tacoma with our dBX Cat-back (part #817615) installed as evidence that our systems not only add that distinct Flowmaster exhaust note but add real world verifiable performance increases over stock.

So about 10HP and 10TQ or so?

 

Yes Sir, I wish we had better numbers on there!

Any numbers on the 2.7?
