    HEY!
    Will i see any gains with any exhaust mods with a stock engine… or do i
    need to have it produce more power to need more exhaust flow? really
    curious and i can’t find answers on forums

    You look a bit like James Blake.

    You don’t necessarily want larger pipe for a header, you want quicker
    exhaust velocity which is why 4 to 1 header is surpass. Larger piping means
    more top end power with a trade up with less low end power. The largest
    difference between stock manifold setup and a header is removing the
    catalytic convertors which are a restriction meant to reduce emissions.

    i know i’m gonna get flamed for this, but i’m wondering if getting a
    upgrade on a minivan such as custom headers
    which design should i go for? ie. 4-2-1 or which
    also when you guys say a “proper tuning” what does this involve?

    Resonance is an issue to be considered when choosing the diameter, yes?

    Hi, I just found out that my 1991 VW Golf stock exhaust header has a
    mechanism that allows it to swerve a small, which after-market exhaust
    headers don’t have. I am wondering if this is the wits that after-market
    exhaust headers crack so straightforwardly?

    Nice video. You said larger piping will have more power in higher rpm, but
    what about if a turbo is added? Smaller piping or larger being that there’s
    more power at a lower rpm. Also is a stock exhaust manifold 4-1 with a
    smaller diameter?

    Hey, I really need help. I am looking to get new exhaust for my 1997
    Lincoln Towncar, but know nothing about which ones I need. The brand would
    be either Magnaflow or Flowmaster. Can someone please help?

    I have been wanting to place headers on my dodge ram but a lot of people are
    telling me that headers leak a lot is this right? And how would you prevent
    them from leaking?

    No, it’s simply routed that way to expel the exhaust gas at the back of the
    vehicle.

    I have 4-2-1 headers (’99 Accord). I did this to keep low-end torque. My
    understanding is that increased back pressure at low RPM’s can really
    INCREASE torque. I find this so counter-intuitive. Do you have an
    explanation for this outcome? Thanks :D
