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
