Presenting SPD's GEN4 Raptor downpipes. Why GEN4?? Ford made a few big changes to the 2024-2025 Raptor 3.5L Ecoboost Engines.  These engines do not have exhaust manifolds and the turbos are bolted directly to the heads. Ford first did this on the 2.7L and 3.0L Ecoboost engines.

Our Industry first Alpha Cats provide ultra high flow while meeting green emission standards.  Factory GEN4 Raptor downpipes are very restrictive because Ford reduces the diameter of their primary cats from 5.5" to 5". This reduction in diameter ( -5 square inches of surface area) causes much higher back pressure and EGTs.  With SPD Alpha ultra high flow cats and larger 3" diameter mandrel bent tubing, you will improve throttle response, mileage and overall performance while reducing turbo lag and exhaust temperatures. Our turbo flanges are CNC laser cut 1/2" 304ss flanges and we TIG & MIG weld the downpipes for strength and durability. We designed in a 4" flex pipe  to absorb shock from engine movement and chassis flex.  Our downpipes do not require custom tuning and can be used as a factory downpipe replacement. Our catalytic convertors are made in the USA and are designed to be used in racing applications.  

SPD Alpha Cats

SPD Alpha Cats are next generation ultra high flow green emissions catalytic convertors and are truly an industry first.  We needed a catalytic convertor that would have high flow and green emissions. Every catalytic convertor that we tested in the industry either had green emissions or high flow but not both.  SPD Alpha Cat is a 500cell catalytic convertor and will out flow our previous 400cell performance cats by +90%. They are extra loaded with Rhodium, which is a platinum based alloy that is required in a catalytic convertor to reduce NOX in the exhaust to meet the new emission standards. 


On all SPD Performance 304 stainless catted downpipes, you get:

  • Increase in performance
  • Improved turbo spool time
  • Better fuel mileage
  • Direct turbo bolt-on design
  • NO CEL - Ultra High Flow 500Cell catalytic converters that do not cause check engine lights
  • 304 Stainless Steel 3" mandrel bent tubing 
  • High grade v-band clamp for a solid seal and no leaks



We use EPA approved federal catalytic converters but you are responsible to verify that they are legal with your state and county laws.

delightful read
Format: Kindle
What a delightful read. The characters are awesome, the plot was so good, I loved it. I was intrigued and it kept me wanting more. Told in multiple pov, the book sucks you in and doesn’t let go. I cannot wait to read the next book.

not bad
Format: Kindle
I loved the plot of this book. The characters just didn’t have a lot of depth. The connections and “love” just weren’t communicated very well in the writing. The author didn’t write the sweet psycho trope very well at all either. Lachlan was just a mess of a character.

A Beta Worth Rooting For
Format: Kindle
In Spare, Violet Fox flips the omegaverse on its head, giving us a Beta heroine determined to make her mark. Joining the Beta Trials to support her sick father, she's thrown into a pack that doesn't want her, especially the possessive Alphas. But here's the twist: their sweet Omega turns out to be her scent match. Cue the angst, forbidden tension, and a slow-burn romance that will make your heart ache in the best way. Violet Fox delivers an emotional, refreshing take on the genre, proving Betas aren't "spares." They're stars.

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.
