  2. Mazda 3 2006 2.0 Maxx Sport Resonator Delete

    2004-2009 Mazda3 Discussion
    Hey guys, i'm new to all of this. I was wondering if anyone has done a resonator delete on the 2.0? How much louder is it? Just got the car and just want to make it sound a little better. An exhaust system is a bit too much $. How much would a resonator delete cost? Thanks
  3. will deleting the muffler and getting a resonator cause any loss in torque?

  4. Vibrant Ultra Quiet resonator

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So... I want that exhaust to be heard a bit more but not at all costs! I checked for options and won't go with pre-made axle backs like CorkSport or RacingBeat. Too much $$$ for what it's worth! I want to do something similar to CS but maybe with just one muffler/resonator... So it would be one...
  5. Intake Resonator Delete?? Custom Cat back?

    Engine / Drivetrain
    So I have a 2016 Mazda 3 i-sport and was wondering if anyone has tried a intake resonator delete on this model and how to do it? If you guys had step by step instructions that would be great! Also has anyone gotten a custom cat back exhaust made and if so how much did it run you and how much...
  6. Resonator is worth 14ft/lbs (so keep it!)

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I have pretty much all access to a dyno shop, so when it comes to testing things for power I can get more than butt-dyno confirmation almost instantly. Yesterday I had the muffler shop cut out the resonator in my `16 2.0 and run a straight segment of pipe. Figured "eh, the resonator is...
  7. Snorkus delete aka Snorkectomy aka Intake Resonator Delete

    2014-2018 Mazda 3 Skyactiv How-To Guides
    Just removed my intake resonator just for fun to see if it'd make any difference to the intake noise - it does a little under power but certainly not overt like a SRI or CAI. 1. Unclip two metal clips on front of airbox. 2. Disconnect MAF plug 3. Pop out the cable clamp for the MAF wire 4...
  8. 3rd gen 2.0L muffler delete pipe with resonator, Mazda flanges etc.

    Buy / Sell / Trade
    Hey everybody, I sold my car but took this off before I sold it. It is loud and not for the faint of heart but the tone is great. Bolts up right where you would disconnect the factory rear muffler. $100.00.
  9. Resonator delete 2L Automatic

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Recently had the resonator taken off and replaced with straight pipe. My verdict. On cold start sounds very raspy. Thankfully you don't drive it around cold. Once it's warm the rasp dies down a lot. It's still there when in high revs but very tolerable. I haven't had any drone whatsoever...
  10. Air box resonator?

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I remember back when the first gen 3's came out, a lot of people were removing their air box resonators to create an intake like sound, without installing an intake. I was curious if the third gen 3's have an air box resonator? If so, would there be any pros and cons to removing it or not...

    2010-13 Mazdaspeed 3 Engine and Performance
    guys just want to know if those of you who have deleted your resonator, did you notice any lost in torque or backpressure? I'm asking because I've been reading and came across this article stating that it gives you noise but you loose backpressure so that been said I want to know from those of...

    Mazdaspeed 3 Parts - Buy / Sell
    Anyone interested in trading their OEM b-pipe off a gen2 Mazdaspeed3 for mine with the resonator cut out and straight-pipe welded in? Not looking for any money, just want to get the OEM pipe in good condition. I'm located in north Orange Coutny, CA and not interested in shipping. Thanks.
  17. Magnaflow muffler & resonator delete

    2010-2013 Mazda 3 Engine and Performance
    After watching Kmac's video of his exhaust I decided to copy him. I bought a Magnaflow muffler #12266 and had my resonator switched out with a straight aluminized pipe (same size as stock piping). I'm not sure if the mechanic had a lot of experience with installing mufflers since he kinda just...

    I have had the resonator gone now for a few months. Im not looking to change the exhaust anytime soon. Possibly a test pipe this summer but thats it. I wanted to post these sound clips as I have had a few people ask me how it sounded and how i was liking it. Its not nealry as deep as a full...
  19. Racing beat and resonator delete

    2010-2013 Mazda 3 Engine and Performance
    I've looked all over for it and I can't seem to find a clip of it. Does anyone have a link to a clip for a 2.5L MZ3 with Racingbeat Exhaust, a short ram intake, and a resonator delete? It doesnt have to have a intake but I'd like to hear one that does because I have an injen+racingbeat exhaust...
  20. Free Mod: Skyactive Intake Resonator Delete/Block Off

    2010-2013 Mazda 3 Engine and Performance
    While I had my bumper off this weekend, I noticed a hemholtz resonator on the drivers side. There are only 3 bolts holding it on, So I took it off to get a look. Although it's before the filter, I didn't want to leave the hole in the intake to allow warm engine air in. Trying to keep...
