Product Details:

The Fabspeed Valvetronic X-Pipe Exhaust System for the 718 4.0L cars wakes up the sleepy Porsche PSE exhaust and gives them a truly exotic sports car sound all while retaining the functionality of PSE (Porsche Sport Exhaust). 

The design process started with 3D scanning the entire exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the X-pipe exhaust system. Fabspeed then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing they settled on using a CAD flow engineered investment cast X-Pipe and 2.5" 63.5 mm tubing for the most power and exotic sports car sound. The CAD flow modeled X-pipe is an exclusive Fabspeed part that gives a smooth high pitched exotic sound and flows much better than a X-Pipe handmade from U bends cut and welded together. The exhaust valves we use are made by Helical Limited in the United Kingdom. These ISO 9001 certified valves are the same ones Ferrari, McLaren and Porsche use on their GT cars. The flanges are thick 304 stainless steel that we CAD designed to perfectly match the OEM flanges and reuse the factory metal gaskets.                 

SOUND: With PSE off our Valvetronic exhaust gives a nice increase in volume without any cabin drone. With PSE on and the valves open it turns the 4.0L's exhaust note into a truly exotic sound with a significant increase in volume. This system will turn heads as you rip by.  

POWER: When used in conjunction with our GPF Delete Over Axle Pipes we saw a gain of 14 HP and 32 ft/lbs of TQ at 2400 RPM, 8 HP and 9 ft/lbs of TQ at 4900 RPM and 12 HP and 8 ft/lbs of TQ at 7500 RPM. This is low end torque you'll really feel around town and horsepower that continues all the way up to redline.

        Rights Didn't Balance the Wrongs
        Format: Kindle
        Eva was sold to a pack as an unregistered Omega by her own father. Unwanted. They wanted her as a means to an end, not for who she was. But she knows the truth. They are her scent matches. They don't realize that because of the suppressants she is on. It's better this way. They would be slaves to biology if they knew, and now she knows the truth. Eva will gain her freedom, and when she does, she will make sure they realize exactly what they lost. I love a rejected mate's story with a good redemption arc. Bring on all the groveling. This wasn't as satisfying as I had hoped for. Too much spice, too little story. There was little romance, affection, or redemption. Consent was questionable. And Eva's fears about biology weren't disproven. The Alphas were controlled by their scent match, and Eva was no better. The Alphas didn't have any character growth. It wasn't only their "Omega" but all of the women they entertained in the house. Even sitting on the couch would have sent an Omega into hysterics. The house and furniture were ruined. Wrongs were done - trafficking, abuse, captivity, dubious sexual encounters. There weren't enough rights to balance out the wrongs, so the Alphas stayed ruined. There were no swoon-worthy declarations or actions. There were some gifts and some redecorating, but most was off-page. Where was the over-the-top shopping trip and romantic gestures? Where were the intimate conversations? Did they ever gain Eva's trust? I'm not even sure "I love you's" were exchanged by everyone. Was there love or only scent? I don't know, so this story was not a success for me.

        Surprisingly good!
        Format: Kindle
        I wasn’t sure I could forgive them and that’s always my issue with betrayal books - can I forgive the mmc, plural in this case, but the author was absolutely able to get me to that point. Yea I struggled with one them especially but overall I loved the book!! Followed the author immediately

        Amazing read!!
        Format: Kindle
        Where to begin. I loved this book. The characters had a way of pulling you in and making you holding your breath at the same time. I absolutely loved the fmc. Eva has a way of being vulnerable but strong. She is unwilling to give up. The mmc’s are truly horrible at the beginning. With that being said, I still found myself rooting for them. Over time you could them changing and how even when they wanted to hate her they just couldn’t find it in them. A truly remarkable love came from a terrible beginning. Loved it!

        Not bad but read better omegaverse
        Format: Kindle
        Mmm. I have feelings. Some not good. Some good. It was an ok read. I've been on a omegaverse kick for awhile now. Love me some groveling alphas but this wasn't it. Actually there wasn't enough groveling and the fmc gave in WAY too quickly. They all have f'ed childhood. The alphas, Dorian, Rafe and Cade met at an orphanage that did unspeakable things to them until Dorian and Rafe aged out at 18 and had ti wait a few years until they could "adopt" Cade, who was 3 years younger than them. They all become successful entrepreneur of sort, I think. They created an app called HeatLink. The fmc, Eva, was sold to the pack by her horrible, abusing father. She endured just as much hardship. She is relentless with escaping the pack but she always gave in when they got too near. Like she couldn't keep her legs closed. She hates them but gave in everytime. I found her kind of weak in that sense. The overall plot was fine. Didn't leave me yearning to read the next page. I did clock one of the identity of someone quickly though. Don't want to spoil it. Again, I've read better omegaverse books. The one good thing about the book is one of the lines from Cade on page 218: ""Please Eva. I'm sorry." She staggered back and I followed her on my knees, dragging myself. I didn't care. I just wanted her to hold me."" I'll admit, I melted a little bit for Cade, even though he was probably the worse a-hole out of the bunch.

        Good Groveling!
        Format: Kindle
        ⭐️⭐️⭐️⭐️.5|🌶️🌶️🌶️🌶️.5 This was really good! Definitely a dark romance! The plot was really good and was done well. I enjoyed the character development but I did wish the FMC told her pack she loved them at the end. Overall I would recommend this to readers who like bully romances and groveling! 💖
