Downpipes/Exhaust
Hey, I was wondering if any of you knows any downpipes/exhaust for cls63 besides supersprint, kleeman, renntech, meisterschaft, agency power?
have any of you use aftermarket downpipes?? what is the best exhaust you think for the cls63?
cuz i dont like resonator delete that much, because its just too much for me...

Why are you discounting all of those players? From what I learned DPs are not that complicated BUT you need to retune your car for them. I put them on along with better filters and the results were amazing. I saw "were" because I didn't retune for it and had to pull them off but Renntech is reflashing for me at no charge...and I didn't even go with them for the pipes. I went with Agency Power.

in terms of sound, which one is better, 200 cells or no cats?
what do you think about a combination of resonator delete + no cats DPs? Do you think it will create too much droning?
and one last question, did you change your spark plugs to racing spark plugs?
Thanks Freefall!

so DPs with 200 cell sport cats still need a retune?
CEL went on after about 30 miles of having the DPs and I was tracking it the next day. We called Renntech and they told me that we need to retune so we put the stock pipes back on. There were no problems at the track.

Yes...from what I heard. The advice I got was cats + res delete or no cats and keep the res. I love the sound of the res delete+DPs with cats....its perfect and legal in CA.
and one last question, did you change your spark plugs to racing spark plugs?
Nope...I had a plug go at about 3000 miles and it was fixed under warrantee and this was after my tune. I've tracked it several times since with no issues.
Thanks Freefall!

For performance wise and take droning as a concern too... so catless+resonator is best?
is it better to throw cat and res delete, or vice versa? i know turbo hates back pressure...
is it possible to do mod on the stock resonator to reduce back pressure, because i have an idea,
if we look inside the stock resonator there it is actually H-pipe.... make a hole in the middle of it..
is it possible to close that hole so it is like resonator with "straight pipe" inside the resonator?
