i am already installing a fujita f5 cold air intake on my 04 mazda 3 2.3l 4 door and i was wondering what exhaust every1 would recommend i have heard good things about the hks hi- power but i dont think it is made for the 4 door

 

I am having a great time with the MazdaSpeed cat-back...it sounds really clean and it's not too loud or ricey.

 

Mazdaspeed hands down. Good gains and clean sound.

 

mazdaspeed/magnaflow are the quietest, from wat i hear.
and from wat ive read, HKS is the loudest.

but i find vibrant, MS, and magnaflow all sound really similar.

oh, and any exhaust will get WAY louder when u add headers.

 

Loudness ftl. I'd love to upgrade everything, but I hate loud exhausts.

If I could find some kind of setup that sounded stock, but gave the exhaust look + performance, I'd buy it.

 

^ Racing Beat is as close as you're gonna get J

 

borla is nice

 

By Borla you mean the MS Axleback right?

 

I think Borla makes a catback too, for the sedan anyways. So, it's a subtle exhaust you say Ken?

 

^^ FYI this is a Mazda3 thread

 

Oh yea .. oops.

 

Hahaha, total threadjack. Good team effort everyone

 

anyone know which one gives the best deep throat sound? i really wanna stay away from the ricer buzzzing noise that everyone hates.

 

My mazdaspeed does not sound ricey and is deeper because it is performance oriented...I also have a CAI. I have heard the Borlas also sound deeper.

 

actually, borla makes a catback for the hatch too!! and thats the one im thinking of getting. the thing runs like $617 so im going to shop around a bit to try and find it a lil cheaper maybe.
