You may have already answered this question in a previous post. If I missed it, sorry. Are you recommending the Breathless unit over the one from Doug Thorley? If so, why?
BTW, thanks for taking the trouble to research and compile this list. It's the voices of people like you that make this site both fun and useful.

I agree
I would also add the Ram Air Intake and Audio upgrades but otherwise looks good!

Not all of these are related to the "performance" of the smart....?
Great list though.

I have a Breathless Exhaust but I think they both are very good Exhausts as long as they provide you a DYNO test that shows an increase in HP. As more and more vendors come out with new products we as customers should ask them to post accurate Dyno test results.

I changed my H7 to Hids and very happy.

One change in the list. I was talking to Evil Twin Smart Car tuners in England and they pointed out the following.
Before you Remap get a good Exhaust because the remap is going to put out allot of gases. To unleash the true power the Smart needs to breath.
"For political reasons a Smart car leaves the
factory heavily restricted and Smart themselves quickly resolved this problem by licensing Brabus to de-restrict the car and develop a handling package."

Adding a layer of 4x4 Dynamat.
I added Dynamat to my 451. Just placed it on the engine cover. I just got a 4x4 piece of Dynamat lifted the black carpet cover over the engine bay and placed it under it. Big change to the inside cabin quietness. Then added some of it to the back trunk opening. Makes a big difference. Check the sound inside my car. I have a BTH sports exhaust.

It would get better with Speed Shifting.
That is where the ECU takes over and up shifts at max RPM. I did not want to push it but still good.
Thanks

What a crock.
The exhausts for the 71 and 61bhp N/A versions are very good BUT heavy.
Brabus do not do a N/A version.
Brabus smarts are another way to get you to part with alot more of your money for very little extra.
A good exhaust will make a difference but not as much as people expect, more to do with weight loss than anything.
Why not go down the route of stock UK version parts from the head to the exhaust silencer?
A 2way cat replaces a 3way BUT you can then put on some sexy TI exhausts that weigh 800grams!!!

The fan that kicks on back in the engine compartment is a blower that blows air into the exhaust to warm up the catalytic converter. Reason being is this is an ultra low emission vehicle. This usually runs for just 20-30 seconds and then shuts off.
