Ahoj, mam c200 coupe, w205. Nahodil som downpipe tiez decat od High Performance. Zacalo mi to rezonovat, az mi triaslo s autom, robilo to ked som stal, zaradene D alebo R. Na volnobehu nic. Dal som naspat seriu a problem odstraneny… moze byt zly kus downpipe ? Mimochodom nauctovali mi za nahodenie downpipe 6h. prace.. kolko ti to trvalo ? Dik

Ahoj nemyslím si že to môže byť spôsobené downpipom skôr si myslím ze to bolo zle uchytené . Trvalo mi to +- trvanie videa

hello, do you change/modify your exhaust? or it's just the catless downpipe?

Hello :) yes the exhaust was modified but it's too loud for me after mod... I put it back the original mufflers

how is the sound with just the catless downpipe? I am thinking to install catless downpipe on my 2016 GLC250 (same engine M274) but I was worried with the sound being too loud. it's a daily car and I use it for school shuttle for my kids, so I don't want the sound to be too much. thank you for your response, much appreciated and regards from Indonesia @@royalcarfactory
