    Wondering if anyone knew if the 4.0 V6 Tacomas had a problem with back pressure if u left off the Catalyc Convertor :confused:. Thinking about going with DT long tube headers, true duel exhaust with a pair of flowmaster 40's :D. Any feedback appreciated, thnx.

    youll gain a little bit of back pressure with the flowmaster cuz of the baffleness, but thats about it

    Nope, what you'll do by removing that backpressure is move some low-end torque to mid-high rpm hp.

    When it comes to towing and hauling that low end torque is needed but for racing you want that mid-high end hp.
