Watched a couple FoST's muffler deletes vids on the tube and may I add I kinda like this inexpensive mod. I may consider this on my FiST if I find a good muffler specialist that deals with mandrel bending piping.

Too expensive...plus my topic refers to non performance enhancing inexpensive sound. Im sure that MRT exhaust produces HP for the money since it has no muffler/resonator.

Hmm. I'm thinking of using the muffler only from my Flowmaster DBx that I had on my Fiesta SE. This would be for just a touch more sound (hopefully?). Offhand does anyone know if the new ST exhaust matches this muffler in 2.25 inch diameter?

the ST exhaust system diameter is 2.17 inches if that helps.

No kidding, that does sound good. Anything that allows better flow has the potential to help power, too. I like the conservative words; it's such a big improvement from the old days of import tuning -- where everyone made wild HP claims about ridiculous stuff. How ironic that we have an import Ford car (yeah, it's a global platform, but without WRC and the fans in Europe who love hot hatches, we'd never have seen this here!). :)

After listening to these videos I can't help but wonder why the turbo doesn't tone down the noise level more. My pre-conception was that the turbo acted as a muffler. So all that noise normally has to go thru a turbo, a catalytic converter, a resonator, and a muffler. Taking out just one of those four seems to really increase the volume.

That's the thing, the turbo does quiet things down! All modern turbo cars also need to worry about placement -- it's a giant heat sink, too. Too far away, and it keeps the catalytic converter from lighting in time. Maybe this plays into sound characteristics too?

Anyhow, I'd say that uncorked turbo cars are a bit quieter than NA. Maybe it's just the tone, but I prefer it to the shrill of NA four cylinders (but love a high RPM song!).

I wanted to update this thread with another video of the muffler delete, I left the stock resonator in there for now, and had the exhaust shop put a bolt flange on there so I could reattach the stock muffler when I want , I like the sound. and there is drone at all
[video=youtube_share;f6au2H_myEE]


and if you are curious about the inside of the muffler I took a picture of it too trough the pipe



Thanks
Chris

Well, I can't say that I care for the sound of the exhaust, but I do believe that I heard the blow-off valve a few times!
