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.





Cleaning TBI - s15 4.3L v6 GMC
It's running a little rough so I decided to clean the injectors a little and clean the grease off all the parts I could get at. Just an update on my truck. Also, looking for answers for why it's spitting a little black soot out of the tail pipe...





My 83' GMC S15 Pickup
V6 3.8 liter 2wd gonna get a 2" suspension lift w/ shocks on it soon, but when the lift came in the friggin box was open and so we called JCWhitney and asked them to replace it, then they call us back a day later and say that they just shipped it. Well 2 weeks went by, and we call back asking where our shit is, and they're like "oh we literally JUST SHIPPED IT today!"
