As my post count would indicate, I am new to the forums and new to the C63. I just sold a couple things and have some extra cash to put in the car, so recommendations on what to get would be helpful.

Some thoughts: ROW boxes and new filters (concerned about CEL though), Logic Lab tuning (looks good but STFA I haven't read any reviews with first hand experience).

Any others or just where to start would be great.

Thanks for any help.

It really depends on what your desired outcome is. If it's a bit more performance and a nice sound improvement, maybe a secondary cat-delete?

ROW boxes shouldn't cause a CEL. It's usually caused by not seating the filters properly when installing them. I never had a CEL from my ROW boxes.

I'd save a little more and get an ECU tune. It'll be the best bang for your buck regarding engine performance in that price range. You could also lower your car if you like that look. AMG door pins are a nice touch to the interior.

Thanks for the responses thus far and for the cat delete didn't even think of it...

Tune or Resonator Delete.

I'd say cosmetic first to get you acquainted to car, then work up to a tune. I am not for de-virginizing a car from day one...

1. Replace yellow side markers
2. Engine Air filters
3. Diffuser
4. Spoiler
5. Lip
6. Emblems, CF parts
7. Tune

Whats the benefits of either a resonater or secondary cat delete ? And would it be the middle resonator that I should remove ?

For appearance, I would add a carbon fiber diffuser and painted or smoked side markers.

Haha, without even reading your post, I did the first three in exactly that order.. Well done!
