    Opinions on Intake & Exhaust system: MPG/HP vs Cost?

    What Intake & Exhaust systems have you found to best increase in MPG/HP vs the purchase investment?

    I've found in the past, I've spent a lot (on certain setups) for somewhere in the neighborhood of 10% gains.

    :cool:

    The best ones are fully boxed intakes, and urd/dynamax/afe/trd/borla/aero turbine are all popular for exhaust

    They won't improve mileage at all, and will make it worse. Free flowing exhaust and intake will make any engine run rich. The mileage improvement occurs when you tune with these less restrictive devices in place, and even then will take many thousands of miles to pay off. You can buy a lot of gas for the ~$1000 intake, exhaust, and tuning cost.

    I'm installing an MBRP dual system, not because I think it will give any functional improvements, but because I grew up in the 60's when any V-type engine HAD to have duals. Didn't matter if it was a '40 Ford Flathead or a 409 Chevy with dual quads. (Hey, everyone has to have justification for what they do and mine is as ridiculous as anybody else's.) I know I won't recoup the cost ever, but I'll also keep the stock system to put back on later if I need to.

    Then you are doing it for the right reason. I run an intake and exhaust too, for the same reason. It sounds nice around redline. Having tuned lots of 1GR-FE's with an actual wideband gauge I can assure you these mods make the motor run rich. Tuning really improves how these motors run...
