ULTIMATE MS6 EXHAUST THREAD

[StreetSpeed6]

This is a post I hope brings fun for the members. My goal is to show all current mazdaspeed 6 and 3 exhaust systems being sold and for everyone to post their setup and a short video/sound clip of the exhaust.

Video preferably outside the car, as it gives you a much better idea of how it sounds whether it is a flyby for just some revs from behind the car. This will also hopefully keep more consistency with sound levels in the videos.

---- Try to list these things when posting ----
Brand
Diameter
Catted or catless
1-10 level of loudness (10 being catless straightpipe)
1-10 drone (10 being can't stand being on the highway)

Here are all options I have found and compiled for the speeds. If I miss any let me know and I'll update this.

2006 Mazdaspeed 6
3" Catless Ebay dp
Stock catback with dual 2.25" in/out magnaflow mufflers

Loudness I give a 7. It's not loud warmed up at idle at all but fairly loud when driving normal and even louder when ripping it.

Drone I give a 6. The mufflers don't stick out past my rear bumper which I think causes much of my droning issues. I don't have a resonator installed to combat this either.

There was a 3" exhaust made by GHL. I think they made one for the 3 and one for the 6. I think they are out of business. It had good fitment on the 6. I heard it had fitment issues on the 3. I had one. I thought it was too damn loud. They might occasionally pop up on for sale ads or eBay or something.

IIRC, ETS, the company most known for intercoolers, also made an exhaust for the 6 at one time. Probably also hard to find.

can i get the link on where to find those mufflers? i have the 3" ebay catless dp, stock catback, to nothing. i just took the mufflers off lol i need something that sounds better and i like the way those sound a lot

 

[StreetSpeed6]

I ran 3" catless dp to regular steel 3" back to the rear axles. Then dual 2.5" out which gives it a bit more of a distinct sound I feel like! They have held up well but they are now much louder after about 8 years or so.
