Catback and CAI

[CanSpeed 3]

So im looking into getting a CAI and exhaust. However im wondering if its a useluess gain without buying headers aswell. Wil the catback exhaust help with the stock headers? or should a full system be the only way to go.

Give me some ideas here guys. Im in no rush gotta get the cash first.
Even comparisons to stock vs full. would help thanks

I am using mazdaspeed CAI and Catback. useless without header? nah man
after u get the catback u will notice the difference. I think the car breath better than b4. I strongly recomand u to install the CAI first.
when i did mine I put CAI and CATback at the same time so I can't hear anything from the CAI,I think that is useless.
try youtube for mazda3 with vibrant header.

Useless no.. but if you have the headers your going to notice...

I agree with 07mazda3boy,
I put in a CAI and Catback separately and you'll notice the difference as you install each individually. It's not a huge gain but it's noticable for sure. More pick-up if anything...I still have yet to get the Vibrant Header...

[mogul_pro]

Same no header for me yet either... would like to hear someone who has one as I know its MUCH MUCH louder and not sure thast something I'd want...

^^ +1 i am refraining from getting a header becuase i hear it gets much louder. currently with my SRI and cat-back it is loud enough for my taste lol

[ksukh]

Lol,
I've heard the exact same...I believe Bubba has one...but I don't wanna get pulled over if it's going to be too loud...

Bubba does have one. He should chime in.
