WOW!!Just put the Focus Central (style)4-1 header with matching flex pipe on my car with the magnaflow "cat" back system.I now have guys on straight pipe Harleys holding their hands over their ears....... it is LOUD!!!! How much louder is this going to get with a blower?(seriously looking at that powerworks one for $3k)

The blower actually won't really make the exhaust any louder... If the noise bothers you, you can have a resonator installed midstream and take about 30% out of it.

^^ Double Tru!

I have a magnaflow based system and my exhaust note sounds quieter and meaner (alot less ricey) than the un-resonated (is that a word?) system.

Don't get me wrong.My exhaust is LOUD,but not tinny or buzzy.It sounds like a Yoshimura exhaust on a liter size motorcycle.I really wasn't expecting that from my Focus.Power is up too.Actually breaks the tires at the top of first now and a 1/2 second squeal outta second.(215/35/18" General UHP's) Can't wait for that blower!!!

I have the Focus Sport I/H/F/E and mine is loud as well. I was thinking about the powerworks blower also. Now I have experience with a Jackson Racing SC on a miata. It made the cars exhaust ALOT LOUDER! When installed on a stock exhaust it's fine. But running an aftermarket 2.25 highflow exhaust with a header it was almost unbareable. I had a highflow cat on it as well. My focus is quiet right now compared to my SC miata. I won't drive another car that loud again.

I put an aftermarket rear exhaust on my Mazdaspeed Miata and the sound level was no different.I suppose the turbo and cat are eating up a lot of the sound.Next week I am planning to replace the downpipe/cat with a straight through 3" pipe.Should spool up faster and spice up the exhaust note.If it was 1/2 as loud as my Foci I would be happy...

It is my understanding that the borla is the quietest of the bunch. With Flow master being the loudest and magnaflow coming in second.

According to TruBendz (http://www.trubendz.com/home.asp?producttype=exhaust&productfor=focus_standard&pagetype=productIndex), the Magnaflow is the quietest, Borla is in the middle, and Flowmaster is the loudest. Just click on each type, and TruBendz describes the tone.

I've got a Magnaflow w/ resonator from TruBendz, OBX 4-2-1 shorty, RT high flow cat, and the flex pipe from TruBendz, and it is pretty freaking loud. I can carry on a conversation in my car, but it's typically not using my indoor voice.
