2006 Silverado 4.3 with Flowmaster 40 Series. Before and After (HD)
Just got a Flowmaster 40 put on my 06' Silverado with the 4.3 V6. Its a single in-dual out Y-piped out to the back with 3.5" chrome tips. It was the EXACT sound I was looking for, and I would recommend it to anyone wanting to make their V6 sound like a V8. As usual, I swear the video doesn't do it justice.. it sounds a lot deeper in person. I promise.
Making your V6 truck sound the best
A comparison of my old *Flowmaster Single chamber race series mufflers* and
my current *Flowmaster OUTLAW mufflers*. The video doesn't do complete
justice for either, around 3 1/2-4 RPM and above the Race series got very
raspy and high (sounding more like a V6). The OUTLAWS keep their tone very
well at even 4-5 RPM and have an awesome sound. The race series rumbled
much different at idle and 2-3 RPM has a smooth tone, but after that
sounded a little to raspy and got high pitched. The OUTLAWS all around
sound fantastic and probably the most close your going to get to a V8.
4.3L flowmaster 40 exhaust
I just installed the flowmaster 40 series on my 4.3L 1995 c1500 W/T.
single in, single out flowmaster 40 with new tailpipe and stainless steel
stock 4.3L. stock cat. stock everything but muffler. 2.5" into cat, 2.25"
in and out of muffler and all the way back to tip.
sorry for bad video quality and putting computer so close to the tip.
also i didn't rev it that high at all - barely tapped it, but since the
camera was so close it might sound raspy. it's just the camera.
you can't really hear it in the video but she sounds like a v8 at idle. my
85 k10 (350ci) sounds just as good swear to God.
anyway its hard to hear on the video but i'm very very happy with the
flowmaster 40 on the 4.3L vortec.
****truck now has magnaflow hi-flow cat, which isn't in this video.
GMC Sierra Magnaflow Exhaust 4.3L V6
My 2011 GMC Sierra. Reg Cab, short box. 4.3L V6. Just added Magnaflow Exhaust. Will never sound like a V8 but
still sounds good for a V6. Seem to feel a difference on accelleration.
Maybe my imagination...lol. Stock motor...so it is what it is! Hope you
Flowmaster Super 50's: GMC Sierra 4.3 Vortec
This is a comparison of the stock Exhaust on my 1999 GMC Sierra Z71 to putting a
Flowmaster Super 50 muffler on it. It has the 4.3 liter Vortec V6 and the
muffler is the only modification I've made to the Exhaust.
Sorry for the truck missing in the video and the bad audio quality. It
needs a little injector cleaner.
Love the super 50's! Not too loud and basically no noise when at cruising
speeds. Great classic tone and mellow sound, which is exactly what I was
looking for. Enjoy!
Custom Straight Pipe SuperTruck Exhaust 4.3L V6
Click here 2:00 to hear It and skip the explanation.
Here is a video on my winter Exhaust
set up for my truck. I cut up my old stock Exhaust piping and fabricated a "super truck"
style Exhaust that exits before the
rear passenger side wheel. Took me about 30 minutes to make. Used my
Lincoln 125A flux core welder to weld the pipe up. I had to weld the Exhaust hanger on while the pipe was
attached to the truck to get it the most room around my cross bar on the
frame and leaf spring shackle. Turned out good its very loud sounds just
like a v8, however it is illegal in the great state of Louisiana, that's
why it is only for winter time. This system and my outlaw both have flanges
so I can switch between the two very easily. 2 nuts and an Exhaust hanger is all that holds it on. It's
definately a one of a kind Exhaust
setup, you don't see it very often! Yes I did in fact weld barefoot, i'm a
redneck that's why im barefoot in all my vids!
Pologize for the iPhone I thought it would be able to handle the loudness
but guess not the sound started cutting out when I went over 4k rpm in the
