    Oh, was it a "emissions compliant" kit? We have no emissions here so most people doing custom headers/exhaust do not bother with the emissions sensors.

    I fucking hated the MBRP high clearance exhaust on my '16 Taco. I've never experienced cabin drone on the highway like that before. Especially with the extra-shitty gearing in the automatic equipped truck lugging the engine under load constantly... It was so bad going uphill I could feel the sound in my sinuses and tear ducts lol... think about that. It did sound good in town though, from red light to red light. Which accounted for less than 5 minutes of my 45 minute commute, haha. Never again.

    Couldn't have said it better. I have a very straight comute on a very flat road. Very little lugging but the drone has gotten old. Sounds good but only sometimes

    Funny, I never thought a custom exhaust was supposed to sound "good". As it is I wear 105 db ear muffs when I drive my diesel, way to loud but breathes better so better towing.

    I'm not sure what the point of putting a exhaust on if you keep the cat and other stuff like O2 sensor.

    Wha...... I don’t even know where to start with this.
    Do you understand how modern fuel injection works?

    Not really, most of my experience up to this point has been with carburetors or throttle body injection or mechanical injection on diesels. In all of these you rip off everything and start from scratch, headers going back to muffler with no sensors or cat or anything.

    No emissions here so no need for extra stuff that reduces flow.

    The O2 sensors in front of the catalytic converter control your fueling.
    The O2 after the cat monitors catalytic efficiency. It will turn in the check engine light if there is no converter or it’s not doing it’s job, burning unburnt fuel.

    Like I said, no emissions. Not overly concerned about what is not being "burned" by cat. You get a much better flow without a cat.

    If I understood modern injection I wouldn't be spending $ next month on Ovtune. Although if I don't get the power I'm looking for I'll probably start ripping out emissions stuff as soon as warranty ends. A little electrical tape on the dash covers up that pesky light.

    You don't need to go crazy. Do what I and St. Germain? did. Install the URD cat delete y pipe and after market exhaust of your choice,you will notice a loss of low end torque/power but top end will improve significantly. I installed a 2 1/2" x 18" spiral louvered glasspack in front of my muffler to restore a little back pressure to deal with the low end torque/power loss and drone. I am quite happy with my system now with the added performance and no pesky check engine light ;)

    This accumulator delete. Is it really that big a difference? I bought the steel line and adaptor so doing it the easy way. With the bleeding, does gravity bleeding work well and any advice? My clutch drives me insane some days. Insanely temperamental

    There is a noticeable difference. Mostly in the consistency of engage and disengage. I hear you can adjust the pedal to change the points where they occur but I never made an attempt. Also, if you ever find the need to intentionally slip the clutch, it is easier to do because now, the clutch plate position is directly proportional to the pedal position, all the time.

    I can not speak to the gravity bleed. I had a helper pump the pedal. The pedal did stay down a few times and had to be pulled back up.

    I might take you up on that, I live in Barrie. Any issues with your install, thinking hard about doing this tune. Overall I really love my truck, but it does have some quirky driveability issues!
