    Hey all, I have a 2011 Mazda 3 sedan 2.0, I’m planning on deleting the current resonator and getting an aftermarket one while still leaving the muffler off. I’m wondering if anyone knows the inlet/outlet diameter and length? Having a hard time finding the correct dimensions. If anyone has a link...

    So I have a 2015 SP25 GT, and I did a muffler delete. Without a resonator delete, I am experiencing intense drone especially when I put spacers inbetween the midpipe and muffler flanges. Does the platform come with a built in reosnator? Does anybody have an exhaust diagram? What can I do to fix...

    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

    Hey everyone, i had muffler delete for a while and do miss the torque at the low rpms, will adding two resonators (one for each side of the exits) even out the torque curve? will i notice the loss in torque? im not talking about any special resonator, just universal resonator. if anyone has done...

    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...

    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...

    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...

    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...

    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.

    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...

    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...

    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...

    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.

    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...
