Hello Driftersmart,

Thank you for reaching out to us.

As Pete said, it would appear that the picture is upside down from the way the header will mount on the vehicle. The outlet will be on the driver's side of the vehicle.

This header is designed for the smart 451 and has been installed by many customers with great results.

If there is anything else we can do to help you, please don't hesitate to reach out to us directly and one of our Team Members will be happy to help.

Thank you again.

Smart Madness,

I’m having trouble finding the above listed header on the website and the link doesn’t seem to pull it up, the only one I can find on the site is made by SFR.

Hello Neon_Guy,

Thank you for reaching out to us. This header has recently been discontinued by the manufacturer.

The SFR Header is a great performance piece for the 451!

This was a great Header - I installed my one recently and together with my Stage2 ECU tune it really brings the 451 to life...

You can feel the added torque and the engine revs so much better for my daily driving. The engine can breathe through the headers.

Surprisingly in contrast to many other users the noise level did not increase at all. Maybe because I use the original exhaust system after the Header.

Thank you again SmartMadness for the quality header and the 50% off!
