451 smart fortwo

I have the "Stealth" version of this system that I just took off my smart and I'm thinking about selling it. There is absolutely nothing wrong with it. I got increased horsepower when I added it and I noticed an appreciable loss when I took it off. I will miss the performance aspect. However, even with the quieter version, it is just too loud for my almost-sixty year old ears. The sound is very cool; has a nice rumble to it. Just not what I want to hear all the time. It took me about an hour to install and about the same to remove. I'm just checking the wind to see if there is a market for it. Breathless is selling it new for $405.

The sound is very cool, just loud for me personally. The performance boost is very noticeable.

Hi John,

Where and how much?

How many horssies did you add?

Did you loose any interior space?

I want to play with my SMART as well.

Thanks for any info you can share!

i took it to Knauz autopark telephone number 1-847-234-2800 i think it gained 12 ponies no interior space lost, everything was in the engine compartment, all i have left to put on are some 17" genius wheels and a carbon fiber air scoop, that will have to wait until next month because of the cold weather in wisconsin, i think i"ll get the armrest by breathless products and that will be it the muffler cost $263.00 to have installed.
hope this helped you,

Hi, I just got my SMART and do want to up the HP's you say the stealth version is loud?

I can imagine what the non stealth is like. I live in S.Fl. and to date my SMART has 13.2 miles on it (broke my ankle as it was being delivered) four weeks after the purchase. Coming from a long history of peppy cars I know I am going to want my little angel to jump when I touch it.

Did you have to re-engineer the back end (exterior) to complete the install? Does the install void the warranty? Where's the best place to get it installed should I decide not to tackle it? Should you decide to part with your exhaust; whats your ballpark estimate?

Thanks and hope to hear from you soon.

Marta in Miami :)

i bought the CES V3 system from breathless, i don"t know where your from but i took my smart to a dealer in lake bluff illinois and no it does not void the warranty, in california they sell the smarts with after market mufflers and k&n air intake systems on them. i would never part with mine i love the way it sounds and it goes like heck.
one happy smart owner,
john j. rodz

Loudness is very subjective. I have no complaints about performance in fact just the opposite. Maybe someone in your area has it so you can check it out...

with your muffler you don"t have the flex pipe, i wonder if that is why you have such a loud sound?

K & N air filter arrived and fitted also changed oil for Castrol SLX 0-30. I must say that it seems to have liberated the engine and there is a quicker response to the accelerator pedal, but then again that could just be me wishful thinking. S...
