New Owner, Best GTS exhaust set up
I just bought a GTs and looking for the best exhaust set up. I have a c63 507 edition and had the secondary cats and res. delete and it sounds amazing. Thinking of doing the same on the GTs. Has anyone done this to their GTs? Or should I opt to go with the Catless downpipes, which is more expensive.
appreciate any insights.
fits at the bottom of the front air intake.

Doing a straight pipe/aftermarket exhaust is useless, as that is the purpose of the valves. But, doing the res delete is definitely worthwhile, as it does indeed change the note/volume.
My vote always goes to downpipes. Kooks Exotics if they can still be sourced or Keller Performance. No hack this, rig this in, chop that.......
To me, we all aspired in some way to work our ways up to the GT platform or whatever high end sports car platform you choose, why chop it up and half a$$ do it like we all did as kids on our starter cars?
It's one thing if you want to be silly with your own money, but trying to guilt people into following your footsteps is pitiful.

AMG has THE best exhaust engineers in the car industry. They killed this exhaust.
I have an M5 and it’s a stupid sounding exhaust.
Downpipes will give you spoons in the kitchen disposal sound if that’s what you want down pipes for a ridiculous price.
Your bias is more than obvious, selling some dream of a better whatever exhaust.
Remove the secondary cats and go from there. IMO.

If the idiot remark was to my comments, then you are a goof ball
.......do none of you realize the biggest restriction in the system is sitting right behind the turbo itself, the quick bend off the housing right into the primary cat. So again, jack around however you like, your car. Beautiful part is you can do to it whatever you like!So again-if the exhaust is soooo great (which i believe it is damn near perfect post downpipe section) then why are people chopping out parts in the pursuit of volume......
But there is the do things right or do it cheap, in my opinion. Some people tape up an extension cord that’s all cut up and some people just buy a new cord, be whichever one you want to be!

And why on earth would you spend all that money on MBH headers you may ask......because it was a few grand on a $70+k car, so not too big a deal for the best scavenging effect highest flow headers I saw data wise. At least from those that shared data.

Next-it is NOT the same result, again, you are NOT eliminating the biggest restriction to the exhaust flow from the turbo, the primary cat that sits right off the backside of the turbo housing when you do the delete of res and 2nd cats.......
WOW-interesting social experiment appearing in this thread, “if you don’t do it my way because I need to justify the decision i made to save money to increase volume then you suck”.....is what I hear from the couple here so adamant about it. Almost makes me wonder if you all are simply trying to convince him to go this route because it is what YOU did to save money, and would be mad if he maybe did it just a little better with downpipes. But again, he’d be an idiot to spend that kind of money......or are you the idiot for not doing it that way and want to make sure the lemmings fall in line and don’t do it better?
Anyway, I shared my preference, based on the OP’s two options.......

Yes, exhaust Button in car still works, as that is controlling the “flaps” in the rear muffler section of car, so you can still go full volume or quiet it down.
