Overview:
The G30 M550i exhaust ushers in a new era of Dinan exhaust design. To date, Dinan has been synonymous with welded on, thin-walled tips and a philosophy of exuding a civilized note when you want it to be, and a pleasantly aggressive one under hard acceleration. While the mantra is maintained, albeit tweaked with the emergence of mid-pipes and resonator deletes to those who want an even more aggressive sound, the styling of the tips is being drastically transformed. The new massive 4" diameter tips on the M550i exhaust are the biggest we have done thus far in addition to being double-walled the polar opposite of our normal thin-walled style. Perhaps most importantly however is the new tips are clamp-on. Not welded as in the past, so they can be easily swapped to new styles or replaced as the need arises.
Internally, the exhaust is typical of other Dinan exhausts and is designed to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow. Like all Dinan exhausts, our M550i Free Flow Axle-Back Exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. In fact, on the G30 M550i equipped with a Dinan exhaust, you will be astounded at how eerily quiet it is in the cabin. That is quickly changed however when exiting the vehicle and being witness to the sporty luxury sedan revving its stout V8 engine with the exhaust valves wide open. Blissfully bellowing a sweet deep tone that begs for more is the reward. When you succumb to those desires the throaty note at full load is even more rewarding letting all those around you know your M550i is seriously capable yet dignified at the same time.
A new era of Dinan exhausts is upon us and they are marked with larger than life replaceable tips.

- More Power: + 8 HP @ 6600 RPM, + 6 LB-FT @ 6600 RPM

Style and comfort doesn't always have to be expensive:
Size: 13, Color: Wingtip Black
I bought this ones mainly because I have used them before and they are great for dancing. Specially salsa dancing. They look really stylish with formal cloth. A great blend of classic "wing tip" with modern details and smooth lines. They fit nice with thin and medium socks and have medium arc support. They will feel better with each use and are very good for salsa ballroom dancing turns on the forefoot and ruber on the heel for safe stops and stability. They fit true to size and foot stays locked in place with the lacing it provides. Great presentation with the box and awsome price for great quality formal shoes.

Nice shoes for about a year and a half
Size: 13 Wide, Color: Brown, Size: 13 Wide, Color: Brown
I bought these shoes about a year and a half ago and they are comfortable and look much more expensive than they actually are. Today, I noticed them starting to tear a little bit, but if I can replace them every 18 months for this price, it is probably still a better value than high end shoes. The grip is good for dress shoes and has held up well, and they are a good fit that does not cause blisters from excessive rubbing. I might not choose these if I need to wear them every day because of their lifespan, but for a once or twice a week pair of dress shoes, they are a good value.

Fantastic Shoe for the Price
Size: 9.5 Wide, Color: Wingtip Black
Okay, I’m used to spending big bucks on men’s dress shoes. I’m talking $300 plus for American made shoes. They are recraftable (resole-able) for another $100 each time.
But since Covid, I don’t go to the office as often. One of my black dress shoes needs to be re-soled, and it will be. Just not now.
So I ran into these shoes on Amazon. It’s hard to argue with the price. Literally 10% of what I have been paying. So, are these shoes 90% lower in quality?
The short, simple answer is, surprisingly, no. Just the opposite.
Upon receipt, I inspected them carefully and they looked pretty darned decent. I was looking for any excuse to plop them back in the box and return them. I couldn’t find anything.
I appreciate that the leather upper is smooth and mildly shiny. This is a wing tip style shoe, so I’m impressed that the extensive stitching was evenly spaced. The leather detailing that I expect on a wing tip is also all there.
Inside the shoe, it is lined from the toes all the way to the heel box… nice! And that leather feels surprisingly supple. That is something I would expect on a much more expensive shoe. But definitely not at this price point.
Hmm.
I even liked the wax laces they chose. They are a little thicker and have more than adequate length. The shoe’s eyelets have interior facing metal grommets to protect against stretching and tear out of the leather and helps protect the laces against friction wear, as they are tightened and loosened over time. Now having that detail, at this price point, has raised both of my eyebrows.
Double hmm. Now I am really impressed.
The only thing that I didn’t like was that the stitching—that joins the uppers to the sole—is white. I needed to polish these shoes anyway, so I figured I’d see what would happen if I put black polish on the stitching.
I’m happy to say that the uppers shine up very nicely, to a high gloss. This was done with just a little bit of buffing, using a traditional horse hair bristled brush. And followed by a buffing cloth. Although I didn’t do it, the leather is smooth enough that I probably could have spit shined them.
And those pesky white stitches on the top side of the soles? Well I’m happy to report that they are now definitely black.
Turning the shoe over, I can visually see a lump where the shank is supposed to be. That’s a good thing. Not all shoes have a shank. It helps to support the arch. That’s another nice detail. I am expecting the shank to be plastic at this price point. So I am utterly shocked to report to you that a magnet sticks to the bottom of the shoe. That shank is steel! Now I am amazed! We’re talking mind blown, Purple smoke everywhere.
Speaking of details, I was very surprised to see the nicely done wing tip detailing, from on top of the shoe, carried over to the bottom of the sole. Wow. I have never seen that before. That’s surprising.
Now it is important to point out that the sole is some man made material. Definitely not leather. But that’s okay. Especially in the wet, leather wears out quickly, if you don’t wear rubber over shoes. One less thing to fuss about.
The heel itself has a band/layer of rust brown material sandwiched between black layers. I wonder if that is a cork or bamboo material? Having walked in these shoes, on concrete and tile floors, last week, there is a noticeable level of cush, or give. They will definitely not to be confused with sneakers. But for dress shoes, this is a pleasant and surprising experience.
The first day, I wore them at home, over the weekend and I’m glad I did that. They needed time to adjust to my feet. Any dress shoe that I have ever worn needs that.
But after that, these shoes have been pleasant enough to walk around in at work.
I’d have to say that these shoes give me at least 90% of what I would expect from my $300+ shoes for around 10% of the cost.
In my estimation, at their current price point, they constitute an excellent deal.
And especially if you are just breaking into the business world and need a good pair of interview shoes, these are definitely respectable… just be sure to put black polish on the white stitches.
Oh, BTW, I have wider feet and I ordered the shoe wide. After the initial stretching, they fit nicely.
So, in the final analysis, what do I think? I have to say, yes, these shoes definitely get my recommendation. Especially if price is a huge factor, then these shoes constitute an excellent deal.
