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
4.3L Vortec V6 with Dual Straight Pipes - Exhaust Vid -HQ- Exhaust video of my 1999 Sierra
Stepside. the truck is filthy in this video. stock cats to 3 inch y-pipe
to 2.5'' duals with 4'' gibson polished mitre tips, all custom done (cut,
bent, and welded,) by myself in my garage when I was 17.
startup, rev, takeoff, flyby, and more revvin!
the truck needs the new updated MPFI injector spider to replace the faulty
stock SCPI spider it has. it has hard time starting when it's warm, its
either the fuel pressure regulator on the spider or a crack in one of the
plastic lines (spider legs). I'm hoping it will make it till summer when
i'll have the time to take the intake manifold apart.
truck has a k&n intake kit
I built this Exhaust system myself
check my other vids. really makes the 4.3 bark. I love this motor its
decent on gas and is very torquey with a killer top end. the 4.3 takes
kindly to simple bolt on mods & tune. I'm looking to get a programmer for
it soon, any suggestions?
After college I plan on building an LQ4 and swapping the motor along with a
4l80e and 12 bolt posi.
Thanks for watching
