H-pipe to keep the AMG sound, X-pipe makes it sound like a 5.0 Mustang. Secondary cat delete will open it up a bit too.

Replace the secondary cats with an H-pipe. Eurocharged or OE tuning for your tune. Done.

You can either go with the trend or make your own to suit you own taste.

Just like in this video:


Straight and X gives it a s..tty mustang like fart.

Thats why.
Let me guess you have a mustang fart setup.

He compared H to X not straight.

Is this the mustang fart sound you're referring to? I don't hear it.

You can hear it on the estate video you posted earlier.

But if you think that it sounds better with an X pipe that’s fine. I just prefer an H pipe.
I actually removed an X pipe on my car which was installed be the previous owner with the factory resonator and it sound a lot better to me.

AMG/ Eisenmann designed the resonator with an H pipe in it. If the resonator is removed it’s just normal that an X pipe would change it and an H pipe would stay closer to the intended sound.

I have zero experience with X pipe. I am commenting on Straight vs H for secondary cats.

Have you heard them both (H vs Straight) in person or are you just going on youtube videos? I have straight and a friend of mine has H. The straight is louder, a little more raw, backfires on decel etc.

That's cool but I'm just talking about Straight vs H in place of the secondary cats. OEM secondary cats are straight and the resonator is an H. Replacing just the secondary cats with straight pipes retains the AMG signature sound.

H-Pipe vid, it's nearly identical as straight.

I wanted to try 2 h pipes in the system also. I have a Mike's power pipe and would switch with someone that has a Mike's h pipe.

I know the 4.0 c63 has 2 h pipes in the exhaust system.

I enjoy the straight pipes setup for catless/res delete. No drone whatsoever. Kept mufflers. The mufflers (not the resonator) are what give the AMG bark hence why our c63 mufflers are very sought after.

Yes as a replacement for the resonator not for the secondary.

That is what OP tried to get an opinion on was the resonator.

If it comes to secondary delete. I would go with a straight as well but for the resonator I would stay with an H setup not X nor straight.

ya I’ve heard them both and have a straight pipe setup. I prefer straight pipe all the way back to stock mufflers from stock headers, including resonator. That was my opinion given to OP.

He considers buying a capristo h pipe.
They only make resonator replacements and not secondary cat replacements.
