MRT has developed a new Rally Sport Exhaust System for the 2014 Ford Fiesta ST. This system is manufactured with 304 grade stainless steel. The MRT Rally Sport Fiesta Exhaust is engineered to maximize the Fiesta ST's performance and gives a great sport sound.


What do you think?

How much? :)

But the question I have would be this. After watching the videos of the ST engineer explain how they tweaked the ST version, with all the parts meant to work together to get the performance they intended - in regards to adding an exhaust system like this, how would it effect their tuning? The engineer had said they tuned the ECU specific to their intake and exhaust. I have seen, and experienced for myself, getting worse performance when mucking about with aftermarket parts added that changed the way a system was designed to work as a whole.

As an example, adding coilovers to lower the car, and adding negative camber, maybe even upgrading the brakes and steel brake hoses - how will it effect their electronic vectoring control used instead of a mechanical LSD? Add to that, the special steering knuckles?

I seen on one of the forums (this one maybe?), where one of the moderators were going to meet the ST engineers soon with member's questions. This should be one of the most important. What mods will not hurt the designed systems they created, as well as which will work with them, and can add performance without an adverse effect on another.

I ask this, because I made some design mistakes (built for SCCA Solo II) long ago when I bought my 2008 R32 in its early days, and not much development had been done for the car at the time. By the time, much later, that the right specs found to work were available, it was too late, and too costly to reverse. Don't want to go through with that again, and now starting with a clean slate. But, I do want my music (exhaust music, that is).

Thats why we remap them ST Rocky.
That is true. But if running in SCCA events, I have rules that give restrictions - can't manually touch turbo boost (mechanically or programmed). Though if adding an intake and/or exhaust "naturally" adds some boost, that is ok. Yes, a total pita, but the same for everyone with a turbo.

Well it all depends on what class you are running. The new street/stock rules for next season still need to be finalized for Solo II so that could effect the G-stock/G-street as the car has been classed that way.

I'm more curious on price as it is not listed on MRT's website yet.

they finally posted it on their site, $699. Seems like a deal to me.

I can't believe this company is 45 minutes away from me, and yet I've never heard of them. I'll definitely be purchasing this, and heading their way in the near future!

699 + shipping + installation for basically a straight piped system? No muffler or resonator in there.....seems a bit pricey to me. You can get a custom one done like that at a race shop with the same quality for a few hundred less.

Yup, my thoughts exactly. Even installing it yourself, which you should bc its an exhaust and easy lol, $699+ S&H is excessive. Plus it sounds like a wet fart..

That seems subjective, looks like a quality build and will pay for it.

Hate to disagree man, but its pretty objective..you're paying $700+ for pipe and a tip. Not to say its not nice/quality, but hardly worth it imo.

699 is a little high for a stainless cat-back but I bet the miltek will be just as high. Could be worse, aftermarket stainless cat-back for a 911 will set you back 3-4 grand...and that is for a muffler and a foot of pipe.

Comparing the price of aftermarket parts for the 911 to the Fiesta ST isn't fair.

Keep in mind I got the same thing for my BMW 135 done for 300$ for two 3 inch pipes..

I wasn't directly comparing I was just making a statement, of course it is not fair to compare those.

As far as I'm concerned on the matter you get what you pay for and for the most part 699.00 is what I have seen for other cars true cat back systems. My stainless exhaust in my evo was 1200...but that was turbo back. I'm curious as to what options will be out for that kind of set up as well, but I haven't seen many and the emissions systems on a 2014 are a LOT different then a 2005 and older.

I'm saying that it is worth it to me, $700 for an exhaust that is constructed very well and in the US as opposed to a lot of the normal low cost stuff people buy. $700 is cheap compared to the stuff that was offered when I had my Cooper S, S2000, 911 etc etc

Dyno plot? Stock vs swapped exhaust vs swapped + tuned? That's going to provide a yardstick for whether or not it's worth the money.
I don't mind the sound. I'd like more noise personally, but i'm not going to throw 7 bills at something I can fab myself in my garage with some 304 stainless tubing.

That seems very expensive to me considering there is no muffler.. heh ;)
