Sorry to go a little off subject re cats, How much is a good set of headers and where from? i have heard good things on the US MB forums but all US dealers! is it a big job to fit a set?
Headers + Map = big sound and big gains?? but is it BIG £££!!

Beautiful work by Hayward and Scott
I had mine decatted and remapped at the same time and the difference in noise and power is far more than I would have expected from a NA car.
So what increase in BHP did the de-cat give?

Hard to quantify, I had a decat completed by a 'specialist'. It was a poor job and I felt the car was not as quick and low down torque was off. I had the car dyno'd and the drop showed in the figures.
I then had the work removed and re done by Haward and scott and the car felt instantly better. Perhaps it was only back to standard but it felt great to have it back and performing really well.
We measured the diameter of the first decat and it was less in a few mm, the welds inside the decat were poor also.
Now I have had Eurocharged tune the car and the difference is massive, especially from 5k revs. A friend of mine has a coupe and mine recently just slightly pulls on his on 8+ separate runs on different slip roads. Both manual and auto mode.
Im very happy, he is just about to order a Eurcharged box and tune.
I had a secondary cat and centre silencer delete on my GF's CLK500, there is no more or no less power but it does sound awesome, in fact it sounds pretty much like a CLK55 now.
PS: it did pass it's MOT but i have been informed that a secondary cat delete on AMG models and it will not pass an MOT, unless of course you know a man.
Will the tester know there is meant to be secondary cats?
