Hi guys, was wondering if anyone had their hands on a Speed3 exhaust that they want to get rid of. I'm looking to get one for my sedan because they sound good, and would like to help another club member out before dumping a ton of cash at an exhaust shop. PM me if you have one, or know of one, so we can discuss pricing/access, etc. Thanks!

Seem to be quite a few on the mazda3 forums.

Here is a good looking CP-E

i have my stock ms3 exhaust that was cut. id be willing to let it go real cheap. it can be re welded

that's cool. Saves a lot on shipping too. There are tons of exhaust shops in town.

In one of those threads a person asked if the MS3 exhaust for sale "was extended to fit a sedan". Not sure if there is a body length difference or not. Do you know?

i have no idea if it will fit on a sedan. there are a lot of curves and bends in it. im sure it can be fabbed to work, but im willing to let it go dirt cheap since the install at a shop will run about 100 bucks

I'm sure AA will be around soon to snatch it up.

I'm not sure how the MS3 exhaust is different from a Mz3 personally, though best guess is larger diameter tubing.

Some MZ3 Exhaust info: http://www.mazda3forums.com/index.php?topic=120315.0

Bumping this for information to other 3 owners, and maybe a moderator can move it to somewhere appropriate. I'll post pictures when I can.

The MS3 exhaust system has a middle section that the regular 3's do not, that connects between the downpipe and the "exhaust system" that gets bought/sold/traded.

Now that I have obtained an MS3 exhaust (thanks Scribz ), I have had the chance to get it underneath my 2.0L sedan and compare/take measurements.



The top is the connection to the N/A engines' downpipe. The black line I have drawn behind the first resonator is where the MS3 exhaust would begin. It will be necessary to cut and weld this first resonator into the MS3 exhaust to make it removable easily later. Behind that, the MS3 exhaust system completely lines up with my stock system, including the hangers!

The only other modification required for sedans like mine: the tip of the exhaust is about 4-6 inches too short, so it will be necessary to extend the tip out to the bumper, or replace it with a tip of your choosing.

Once the exhaust has been installed, I shall take new pictures of the modified sections and edit them into this post.

We need before and after vids of the sound too!

what is the change in the exhaust diameter?

Stock 3 is 2", stock MS3 is 2.5", 2.75" at the tip.

But the biggest difference is the removal of the huge muffler on the reg 3's.

you get this bad boy installed yet? i was so embarassed about how dirty my car was i washed it as soon as you left lol

Lol. Not yet, it's gonna be next week, my exhaust shop is closed for the holidays. I doubt I'll be able to get a before video, but I have several pictures. See what I can come up with though. Definitely going to take an after vid though

exhaust pro's? on colfax and chester or clinton?

they do some of the best work and have good prices. my dad got a brand new muffler and exhaust hangers and tip all welded for about 103$ on his accord.

Need a vid to compare sound properly. Why no vid

I'll try to get a vid up of before, but I have never posted a video, nor do I really have a camera. I'll do my best.
