    Gonna run two straight pipes to 2 SpinTechs, they sound really good to me. I have a buddy who owns a expertire here and also the whole crew is pretty cool with me so I get inspections and Emissions passed pretty easily haha

    Thats nice. It's always about what sounds best to you. I live in a county with no emissions testing so I run what sounds best to me but the parts of Georgia that have emissions it's about impossible change the results. Also for the little bit of performance a gain it might be I use a 3 inch pipe from the y pipe to the muffler then two bends and exits. The less the bends the better the flow. And it's actually the same size and length of the stock mid pipe. I think I've become addicted to all my trucks have exits in front of the rear tires

    Do shorties flow any better than stock manifolds? Which are better for low end performance, short tube or long tube?
    I don't care about which sounds better.

    Long tub creates more scavenging effect I just like the way the shorties fit and look.
