Downpipes questions for 2020 glc63s.
Basically, need this car louder. Coming from a 2015 mustang GT with axleback and res delete and that was perfect for me. A 6000-8000 USD exhaust seems ridiculous for me. I also may want to tune it in future so catted downpipes seem like the best option for me. Questions.
1) How is the sound level?
2) How is the sound quality?
3) Do downpipes themselves raise any warranty issues?
4) Thought I read about codes being thrown in the past from aftermarket downpipes?
5) Recommendations for bang for buck downpipes? Companies that is.
Thanks for any help.
if you want catless i have a ssr catless I’m getting rid of
Edit: if you want to pass smog just knock out the 2nd cats, that way you are not dropping your tranny or cutting up your oem for aftermarket install.
i personally think it’s a very dumb move if you spend few grand on GESI catted downpipe and not tune
