Well, luckily I have received a shipping notification for my Dinan exhaust…should be receiving it next week.

Hopefully by next weekend I’ll have it installed. I will update this thread with any installation tips, instructions, etc. followed by of course videos and impressions

Ha...if you can't wait, imagine me??

The box is looking sweet in my garage, happily surprised that it only took me a few weeks to get it.

Coordinating with the muffler shop, either this weekend or next for sure: we discussed to tig-weld all joining parts (no brackets or clamps here), cut the OEM like the pictures above, so likely the x-pipe won't be needed.

Dinan axleback is now Done!!!

Initial impressions- DAYUMMMMM. My M2C now sounds absolutely freaking amazing!! Loud just enough, MUCH DEEPER growl and tone, and just as important, I experienced ZERO rasp on my 1hr drive back from the shop. I found myself keeping in 2nd or 3rd gear only because, well - it's so enjoyable!!!

OK, settle down boyo, but what about the installation?

Installation cliff notes:

- didn't need the included x-pipe
- removed the clamps/brackets that came with the AA EL & mig welded instead (thought the shop would do tig, but mig welding works just as well). These are AA extenders that connect the ends of EL to the OEM piping
- didn't use the Dinan brackets either; shop ended up fabricating custom elbow joints & welded them. Note: Dinan pipes are 70mm in diameter, OEM are 65mm
- shop cut the OEM exhaust around the diff area

Pictures speak 1000 words…see attached!

Installer: I ended up using https://kinneysmufflershop.com/. This shop is absolutely fantastic to work with, extremely knowledgeable, very pleasant, listens to customers, patient. If you're in DFW area, I highly recommend Jesus (foreman) or Dirk (owner).

Cost: ~ $550. Note, it would have been cheaper but I asked to weld everything that is bracketed, thus I paid more for custom connectors and welding.

Installation time: about 4 hrs

Conclusion: Dinan is 5 stars exhaust, and the pairing with AA EL makes my S55 -M2C sound MONEY!!

PS yeah, I know I owe some videos, working on it. Need something more/better than an iPhone 11 to accurately capture this beast noise!!

Loosing some weight also helps (I'd say Dinan is ~ 1/2 as heavy as the OEM). No sagging balls/cow udder look either.

One of the best mods I have ever done!

Did it help fix any issues you've had before with the equal length? Maybe welding is the way to go instead of clamping

Yes…my initial thoughts given my drive back home from the shop:

- sound/tone is significantly deeper; feels like it dropped a few octaves, entire RPM range
- encountered no raspiness from 1500-2000 RPM (like I did w/ AA EL only)
- grumbles more, feels like it wants to burble, but not quite
- cold starts are about same as before.
- has a more noticeable 'braap' on up shifting/letting off throttle
- as expected, efficient is very manageable, would be perfect for a long hwy drive. No drone
- from a loudness POV, sport is about as loud as Sport+ w/ AA EL only. No drone, zero raspiness throughout several throttle blipping sessions
- sport+ is perfect when you want to be a hooligan! Zero raspiness found, but occasional drone (few tries ~3k (ish), 3rd gear, doing 60mph).
- the difference between Efficient/Sport is now more noticeable …the deeper growl is clearly evident/heard.
- sport growl level 7 vs sport + growl level 10

Glorious upgrade- super happy!!

Hey, sorry, forgot that I didn't specifically answered your question.

With the Dinan axleback now in place, it DEFINITELY cleaned up any raspiness that I had with the non-res AA EL only; now I can't tell you if the welding helped 100% or not, but I am not a fan of clamps and brackets. These eventually fail and loosen up over time, so I wanted a solid & permanent connection.

Working to upload several videos I've taken just this afternoon: without a doubt, the Dinan isn't coming off my car.

There you go boys and girls: enjoy...I am still smiling!!!

That sounds bitch’n! Congratulations! Love that you had it welded. I might have to try that out with my AA EL resonated mid-pipe after I save up another couple grand!

[No_curebimmer]

Alright...found some empty parking lot...stationary revs at the end (around 1:14 is Efficient for 3 revs, then Sport for a few revs, finished strong with Sport+).

Sounds incredible!
Might consider this if the EL midpipe alone isn't enough, but I am not a fan of droning of any sort.

I totally get that, but the drone is a really nice one, not annoying in any sense: the car is more alive, more communicative! If going on a road trip, put it in Efficient mode and no drone whatsoever.
