hi there,

My name is victor and i am really far from you guys( i am from Sao Paulo - brazil). There is no information enough here regarding exhaust setup.
My car is a stg1 tune for premium gas but with original exhaust system. I really like the original sound but i would like to increase a litle bit more performance without big diferences in the exhaust sound /volume( and without ressonance as well)..

what should i do? install long tube headers maintaining the other sections or juste remove the first cats( thats close to engine).

first of all , sorry about my poor english and congrats for this forum( i did a research and this is the best place to share c63 opinions)...

Research is your friend, but you have to look a bit more. There are A TON of threads about your question. I'll help out some though - https://mbworld.org/forums/c63-amg-w...info-noob.html

You can remove the secondary cats and replace it with straight pipe to increase the sound a bit (25ish% louder & no drone).
