Hello, I did see your post.
All I can say is what others have already said.... you will need complete original G63 exhaust or at least original G63 mufflers.
When I purchased my G63 parts, I purchased complete exhaust from headers. It included downpipes and mufflers. Flanges on the G63 downpipes did not work with G500 headers so i had to cut the flanges off and weld them on to original G500 flanges.

With everything installed, my G500 does sound like G63, I love it! ))

I wish you best of luck, I hope you find the sound you are looking for.

that sounds great, do you mind showing a video of how it sounds? i would love to hear it. and that must of costed a ton of money, killing your wallet lol

Kobzarhomes

Ill try to record a sound clip sometimes, not sure when. Maybe when the truck is finished.

jdbenz500

and isn't adding headers and downpipes going to make the car super crazy loud? unlike the g63, which has a deep quiet rumbling sound?

Kobzarhomes

Customer headers might make it a bit louder. I might do custom headers sometime in the future (maybe), but with the current setup it sounds like a G63.

jdbenz500

how much cheapest will all this come up to? just an estimate

jdbenz500

I'm looking towards the replica g63 exhaust from china, the headers, and downpipes.

and do i need to change my g500 cats to the g63 ones? or I'm good?

Kobzarhomes

Not sure how much it will cost you, depends where you get them. I bought mine with the rest of the parts.
Mine has G63 cats so Im not sure how it will sound without G63 cats.

jdbenz500

oh ok. to be honest, i think if you really want the exact g63 sound with your current setup, all you need is a engine tune up.

Kobzarhomes

Not really sure what you mean by your last comment when you say engine tune up...

I have a stock G500 engine with full G63 exhaust and it sound exactly like G63

jdbenz500

yes, your setup is perfect. but other people told me the engine is not the same, therefore somehow producing different horsepower and air flow

jdbenz500

its amazing if the sound on your current setup is exactly the same as a g63

jdbenz500

and isn't it supposed to have 2 cats on each side?

G63 has only one cat

What are your interior plans beside the seat swap? This build is awesome!

Kobzarhomes

Thank you !
The plan for the interior is to update the dash with 2012 parts, hydro dip wood trim, install black carpet and reupholster entire interior in leather. Dash, door panels, wrap all plastic trim in leather. Basically similar to what Brabus does to their interiors. ))

hutch300

That will be awesome! When your done you should show it off to the local forum members, I know I'd love to see it!

Kobzarhomes

Yes, I will be posting pictures of the progress and final product.

hutch300

I meant in person

Kobzarhomes

Oh ok.
Ill probably take it to local car meets.

jdbenz500

thats odd, the g55 has 2 cats and sounds very identical to the g63.

jdbenz500

i have a feeling the g63 cats are large enough to act as 2 g55 cats...

Today I started by wanting to take care of couple of small rust spots on the floor, but then decided to refinish and put a fresh coat of paint on the entire floor just to make it look uniform and fresh

Looking good. One step at a time. Just because you won't be able to see it when finished doesn't make it unimportant.
