    It helps the ECU learn faster. I always reset it when I mod my intake or exhaust. I also reset it when I clean my air filter.

    You are right, there is nothing wrong so you don't have to reset it.

    Either by unplugging the ECU fuse, or the (-) terminal of the battery.

    I don't know about the audio lock. I don't think I have that on my car. My fiancee's car has it though; the radio locked when her battery died earlier this year. I assume if you have audio lock it would kick in when you disconnect the battery.

    Wondering where people are installing their aftermarket resinators on the MS3 system?
    I installed mine last night & it's already quietened down quite a bit, but with it my daily driver I was thinking about trying to tone it down even more. I usually add in a Cherry Bomb glass pack as they are only $20, but not sure if I should remove the 1st OEM resinator & add it in there? I also removed the 2nd cat also.

    Right there, some race pipe the second cat and later on add in a Vibrant or some other company resonator where it was.

    I'll have my car on the lift some time in the next week or two, so I'll snap a pic for you. I'm running a vibrant ultra quiet resonator between in the center tunnel between my seconday cat and the part where the exhaust turns 90* to the drivers side.

    Wondering how much quieter the exhaust gets with a resinator installed?. I picked up a 34" long cherry bomb glass pack last night that I'm going to throw in this weekend. I know that on my GTP I installed one to quieten down my Borla's & it actually made my 3.8 sound sweet & they normally sound like crap. I'm just hoping for the same results on my 3.

    I had the MazdaSpeed exhaust installed on my Mazda 3 Sport GT this week.

    The MS exhaust is shorter by about a foot so a flange had to be made to be installed to extend it.

    Sounds great!

    I am also hoping it gets a little quieter, especially in the car.

    What could I do to make it quieter inside?

    I am afraid it will freak out my dog.

    Heads do trun to check it out though.

    Thanks.

    Glad to hear it Ben...so is yours a stock MS3 with an extra resonator on it...and which portion are u cutting the section before or after the cat?
