>Designed for racing, track events and off-road use, Fabspeed's Long Tube Competition Race Headers with integral Side Muffler Bypass Pipes are designed to maximize the horsepower and torque bolt-on potential of the Porsche 991 GT3 / GT3 RS / 911 R engine by increasing exhaust flow from the engine cylinders straight into the exhaust system. This system was designed, incrementally dyno developed and maximizes engine power all throughout the powerband.When the first 991 GT3s landed on North American soil, our engineering team immediately got to work and developed a Race Header to maximize the performance of the track weapon. Our original medium tube modular header design was very successful, but we were looking for more power. Consequently, we were approached to enhance a GT3 RS and welcomed the opportunity to refine our long tube header design further. After extensive development, including dyno and track testing of various designs, we’ve uncovered the correct formula to unlock the maximum performance and exhaust flow from the Porsche 991 GT3 / GT3 RS / 911 R. There is no better designed and engineered race header system for the Porsche 991 GT3 / GT3 RS / 911 R available worldwide. The Fabspeed Motorsport GT3 header was developed in conjunction with the racing engineers at Burns Stainless LLC Costa Mesa California. Burns Stainless is a World leader and innovator in stainless steel header design, testing and building high velocity merge collectors.

oh wow
Format: Kindle
I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat.
It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot.
Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable.
The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold.
The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.
