Overview:

This American Thunder® Cat-back exhaust system is designed for the 2015-2023 Dodge Challenger Hellcat and Demon with the 6.2L engine, the SRT392 and R/T Scat Pack models with the 6.4L engine, as well as the 2017-2022 R/T with the 5.7L engine and is perfect for the person looking for an aggressive exterior sound level while maintaining a moderate interior sound with all of the performance benefits that you would expect from Flowmaster®. This bolt-on 409S stainless steel system features mandrel-bent dual 3.00-inch tubing flowing into our exclusive Scavenger Series® X-pipe assembly for maximum power and a deep unique tone. The tubing then flows into a pair of specially built Super 40 ®Series mufflers and the tailpipes include "dummy valve stands" to fool your factory actuators into thinking they're still operating the OE valves. This way, you always have that "wide-open" sound and performance without throwing a code. The stainless steel tailpipes are finished off with Quad 3.50-inch polished 304 stainless steel tips exiting within the rear bumper valence. The system uses the factory hanger locations for an easy installation and is covered by our Lifetime Limited Warranty. Includes all necessary parts and hardware for installation. Note: This system eliminates the Factory Exhaust Valves and provides "Dummy" valve stands so the Factory Acutators still work without throwing off a code.

    Lovely
    Format: Kindle
    Lovely and sweet. He falls first & the yearning is perfect. Slow burn, but sexy. Both main characters were relatable and likable.

    Letdown after ESA & OGS but Still a Great Summer Read
    Format: Hardcover
    Highly anticipated after 2025's One Golden Summer sequel to Every Summer After because The Florek boys are everything. Loved the setting (Tofino sounds gorgeous), but the book was off balance. Long-suffering George was so thoughtful & obviously in love with his BFF Frankie. Other than shared history, I wondered why. She's supposed to be independent (as was Jo in her fave book Little Women), but she spends a lot of time sobbing, moping, resenting, & pushing everyone away. She's oblivious to George's obvious devotion even when he's traveling the world for work & firmly consigns him to the friend zone (but doesn't date anyone else beyond a device driven brief engagement to wildly unsuitable guy). At 30, she still thinks romance will kill their 22 yr friendship? Even their magical week in Tofino when they're together is unsettled by her reticence & constant disbelief they can be a couple. There are a lot of flashbacks to the besties at 8, 12, 16, 20, & last year that disrupt the flow & don't serve the story. Still, she writes beautiful sentences and has the ability to transport. It's a good book, just a 4 not a 5.

    George was awesome...the setting was beautiful...not a fan of Frankie
    Format: Hardcover
    I had to buy this book since One Golden Summer was amazing and stayed with me longer after I finished it. In this book, the setting and descriptive scenery of their honeymoon destination and how it was woven into the story was the highlight. The romance took second place and was lackluster overall as I never really connected with why Frankie was such a good friend and George fell in love with her. The ending was just okay and I think the letters could have been better utilized in the story instead of dumped in at the end. The whale storyline was a footnote and distracted from the story. It could have been a few chapters shorter overall. I loved George and felt like he deserved better.

    OH, GEORGE!!! 😮‍💨🫠 What a perfect friends to lovers summery romance. Fortune has become a fast favorite of mine to just make my heart ache. Yes, Frankie is oblivious, slow and frustrating at times but it was such a lovely, scenic and magical story! 🥰🥰🥰

    predictable but enjoyable
    Format: Kindle
    Very obvious plot, but still enjoyed the character and storyline development. If you’re looking for a mindless, easy romance then I would recommend this.
