Hey guys, Just found this vid on Youtube, Don't know if anyone here, has an aftermarket exhaust on their 2011's yet, But I found this of the 5.0L It sounds really good to me! A little different from the 5.4L


(2011 5.0L Borla Exhaust)

(2011 5.0L Flowmaster Super 44)

YouTube - 2011 F-150 5.0 Flowmaster Super 44

 

I liked the borla better, but maybe just cause the sound is crappy on the flowmaster clip. I can't wait to get a magnaflow on mine. I wonder if I'll gain anything other than more noise with it tho, the new design is pretty good?

 

Yeah I liked the Borla better too. And your right, I wonder if these engine's will see and improvements as they already breathing good. I guess only time will tell.

I use to have an old 1990 F-150 with the old Pushrod 5.0L and I did the full exhaust treatment on it, True duel flowmasters, Headers, Single highflow Cat...The works, that truck gained almost 40hp from that alone. I doubt you'll see gains like that in these newer trucks.

 

I got to dive under a 5.0 truck at my dealer w/ a tape measure. I didn't have a lot of time, but it looks like the headpipes are about 2.5", and the rest of the system including tailpipe is a full 3". I MAY be a bit off on the headpipe as I couldn't see the tape too well while checking it, but the rest IS 3". Being that just about all after market systems nowdays are 3" catback systems, I wonder if they'll go bigger, say, to 3.25 or 3.5", on the single pipe before the muffler, or if the 3" stock pipe is actually big enough to send 360HP worth of spent gases on their way.
Looks like this could be open to some speculation....

 

I agree that the sound reproduction of the Flowmaster is crappy, but I would never use a 44 or 40 series Flowmaster myself, as they are too loud for my tastes. A 50 series Big Block would be a lot mellower and flow just as well, and not be as obtrusive.

 

That Borla does sound great.

I wonder what about the 5.0 is that gives it that raspy sound?

I have the Borla on my Tundra and it sounds amazing too, but definitely a different sound than the 5.0 F150

I would say it's the state of tune that allows a 5.0L engine the ability to crank out 360HP. The variable cam timing feature allows for "radical" timing in the upper ranges, but "mild" timing in the lower ranges for a smooth idle. A little over-simplified, but basically true.

 

Very interesting.

If I were to buy a truck tomorrow it'd be a 5.0. Sweet truck and a sweet motor. I'm in it for the long haul in my Tundra though. Only 57ish k miles so it's still got some life left in it.

That flowmaster didn't sound to bad. The borla was to raspy for me.

 

I have a feeling that ANY muffler is going to sound more raspy behind the 5.0 compared to other engines just because of its high state of tune AND the higher RPMs it can turn. Would any of us complain of this trait? Not me......

 

I've heard the Borla & Flowmaster 44's in person...had the Flowmater 44's on my truck for 5 days....wne t back to what I have run on all my vehicles for 30 years...Allied,

Tone is deeper, much nicer rumble, flow is equal to either Borla or Flowmaster


Yeah, IMHO

 

Factory is good with me... I despise the Borla sound greatly... I never want to sound like that pile of garbage!

 

I hate to say it, but that's the motor man. The stock 5.0 sounds very similar just a little muffled.

Listen to Borla on a C5 or a C6 Corvette... or a Mustang... or anything else and you'll just about cream yourself. I think it's one of the best sounding mufflers.

What is your opinion of the tundra after 50K,how is the mileage, any significant problems to mention???

 

In my 57k miles, I had a new water pump at like 45-50k miles and a serpentine belt.

I've had my front diff rebuilt around 54k miles.

Air injection pumps are a multi-thousand dollar problem but can be bypassed at no charge... but you may need to pass inspection.

Honestly, the best things I"ve done to this truck is the Old Man Emu suspension up front, the ranch hand brush guard, tires and exhaust. The factory stuff is good, but everything else makes it better.

The powertrain is STOUT, and people over on the Tundra forums say it's better than the new Fords in races... personally I'd buy a 5.0 whether or not it's slower or faster. Not a big deal as they all offer plenty of power.

The sheet metal is weak, but I assume all trucks are now a days in the 1/2 ton market.

All in all, good truck but it leaves a LITTLE bit to be desired. Put me in the market today, and I'd probably buy a Ford but I"ve always been partial to Fords. The Tundra is a good truck and not to be discounted totally b/c it's "japanese."

The other thing is I have a very early first model '07. Might be a little bit more susceptible to problems.

If you go onto the Tundra boards you'll see what the majority of the problems are. Nothing TOO significant that affects the entire tundra population except the air injection pumps.... mechanically. All of them have thin sheetmetal, poor paint, etc... but what car doesn't htese days?
