Being a lazy Monday, I met up at my neighbors shop this late morning. (Monday mornings usually busy for him but today was quiet...) and did a copycat of what David did here
Put my rusty welding skills to work in his shop (made sure I had my safety boots/googles on and coveralls)
(And please don't laugh or ridicule me too hard for my welds. May not look like much but they work fine and hey, it's my dream,
so go get your own dream)
Oem muffler removal was easy. My favorite tool for most things - the sawzall.
Took me about 45mins to complete the job. The owner (my neighbor), he just stood there drinking coffee, watching my pre-apprentice welding skills, looking busy and trying to hold back his laughter.
Not much help although he did open up the new muffler ends for me and cut the splicing tubes.
Tested for leaks. Done.
Happy with the results and the muffler growl, as David mentions and shows in his video, is nice.
Thanks David for your post. Helped immensely in my diy muffler swap (with my purdy welding skills).
Onto the coilovers, once the bloody parts are in.
Very nice job !
Welds look fine, too.
Looks like you got the same muffler, the Rumble one I used - correct ?
Do you still have your 2nd set of rear Cats ?
As much as I respect Matt's advice, all I can add is:
IF your 2nd Cats are gone (as mine are & were...) ditching the resonator MAY make more drone than you or your wife or passengers like.
It did for me. But I was committed to keeping the 2nd Cats gone, because in my case they were partially plugged for sure.
The thing Matt or others may not appreciate if they don't have the Rumble muffler in hand and do a direct comparison to the oem factory muffler, is just how minimalist of a piece it is.
Weight wise, we're talking:
12# versus 40# + so you are loosing serious sound deadening mass.
Right now, it's loud enough that if my wife learned how to weld, or who to hire, I'd find the ML back to stock by dinner time.
So, careful on the noise factor.
I just moderated the Comments on my Youtube for this topic and one commentor replicated my exact setup and thought it was too loud, then had to change it back to the tune of $400.
I felt bad for him, but I think he did things in one fell swoop, when exhaust changes are best & safest done incrementally as possible.
Khomer let us know what changes pro or con you observe in the ML's overall operation ok ?
I'm gratified & amazed that my Youtube video on this now has 2400 views in just the short year it's been up & appears to be ranked 2nd for ML exhaust videos.
For fun, I added a Poll feature to find out what Mercedes Forums people are subscribed to on the video.
For any who want to watch (or re-watch) it, please take a moment to click the "Benzworld.org" button when the poll comes up.
You don't have to wait tho, just hit the little round "I" button that appears top right when you mouse over the video controls, that makes the poll panel pop out.
Cheers - David in East Texas
