PROFILE
The ARM F82 M4 Downpipes are the ultimate solution for improving power, throttle response, and exhaust note on your S55 powered M4. Our goal for the ARM M4 Downpipes was to provide a solution that would maximize power and torque, fit perfectly, and sound extraordinary.
Catless downpipes are considered a standard upgrade for any F82 M4 owner looking to safely push their S55 engine beyond basic Stage 1 tuning. With Stage 2 and up tuning, higher boost increases back-pressure at the OEM catalysts and chokes the S55's turbochargers, causing them to work harder and shortening their life.
The ARM F82 M4 Downpipes relieve the stressful back-pressure caused by high-boost tunes, allowing the exhaust to flow freely, increasing power and torque, all while extending the longevity of your S55's turbochargers. On our test car, after installing our F82 downpipes and switching to a Stage 2 flash we made 543whp and 547wtq, this is 73whp and 126wtq gain over the stock results!
Even with the Resonated ARM F82 M4 Downpipes installed on your stock-tune S55, you will notice an increase in power, torque and responsiveness. Not to mention the incredible, head-turning sounds your M4 will make under part and full throttle.
RUMBLE, NOT RASP.
The ARM Resonated S55 Downpipes give your F82 M4 an unparalleled sound that even other M4 owners will notice. The deep, aggressive tone of the ARM F82 M4 Resonated Downpipes will stand out next to the all too familiar high-pitched rasp of other catless downpipes. Our 4" resonators are installed in the perfect location to enhance the sound of your S55 without compromising the precise fitment of our M4 downpipes.
Alternatively you can opt for the catted version which replaces the resonators on each downpipe with a 200 cell catalysts to help reduce emissions.

CONSTRUCTION
Precision CNC machined v-band flanges offer a smooth transition of exhaust gasses from the the turbochargers to the ARM S55 Downpipes. The body of the 3" ARM M4 Downpipes are constructed of SS304 Stainless-Steel and are threaded smoothly and perfectly though the space given by BMW towards the mid-pipe section.
Any downpipes that bolt up directly to the OEM mid-pipes must reduce to the 2.5" to meet the size of the OEM mid-pipes. Some aftermarket downpipes use an abrupt, short reducer which causes turbulence in the exhaust gasses. The ARM F82 M4 Downpipes feature a smooth, gradual transition from the 3" inlet to the 2.5" exit for optimum exhaust flow.
The ARM M4 Downpipes are a massive improvement over the OEM S55 downpipes, with precise fitment and brilliant finish the ARM S55 Resonated Downpipes are the perfect solution for your S55 project. Our goal for the ARM F82 M4 Downpipes was to provide a solution that would maximize power/torque, fit perfectly, and sound uniquely extraordinary. We are so confident that you'll agree we've achieved this, we back every set of our ARM F82 M4 Resonated Downpipes with a 30 Day Money-Back Guarantee and the ARM Lifetime Free-Replacement Warranty.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters.
That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception.
SPOILER:
The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured.
I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

Fun with a late blooming omega
Format: Kindle
I like this book. The story is fun, cute, and sexy. There's just a little drama, some excellent, steamy scenes, and a fairly good relationship building storyline. I especially like how all the main characters are a bit older than the usual 20 somethings I tend to see in this kind of book.
Having said that, I wish there were more descriptions of the places, as well as the food in the fancy restaurant. I enjoyed the cocktails at the club, so I missed that kind of detail when Gray took Madison on a dinner date. I also wish there had been more interaction between Lucas and Madison, and Lucas and Rian. It felt a bit lopsided, with a focus on Rian, Madison, and Gray.
I wish it had been proofread - there are a lot of typos, but nothing too distracting.

Madison Deserved Better
Format: Kindle
Madison was a beta...except she wasn't any longer. She was a late presenting Omega. And she was struggling. She was tall and thin, not tiny and curvy. She was opinionated. She was everything an Omega was not. After suffering through her first heat, her friends took her to Ardor, a club where Omegas came to safely find Alphas. She's not expecting much but then she connects with a sexy beta. And when she meets his Alphas, they set her body on fire. Maybe, she's found her no-strings-attached heat pack. Maybe, she's found something more.
I could not connect with the characters in this book, so their story never resonated with me. And there was no love story; there was sex. Grey made it clear from the beginning that he had a true love and it was his beta boy, Rian. He went so far as to reassure Rian “Say the word, I’ll never touch her again. Lucas can put the babies in her. I only need you, beta boy”. So, Madison was there for babies, no emotions needed. Nice. No, thank you. I want the Omega to be the center of their world, not an incubator. Lucas and Rian weren't any better. After her heat, they let her leave. Not one of them made her feel valued. No one gave her a reason to stay or even offered a cuddle. And the sex didn't even come across as mind-blowing. Madison deserved better.
