Next Up. SPD Catted Downpipes On 2025 RR

[ZombieDropper]

I ordered these on Tuesday, had a tracking number the same day and they showed up on Friday. These are beautiful with excellent workmanship. It's almost a shame to hide these under the truck. Even though these are twice the price of FenFab pipes a lot of the money goes into the 500 cell cats which SPD is claiming a +90% flow increase over the 400 cell. Isn't increased flow the biggest reason for changing downpipes? Fenfab still only offers a 400 cell cat. Also I understand that Fenfab can't seem to fill their orders and folks have been waiting for 2 months plus. I also just installed a TurboSmart Kompact EM Dual Port BOV. Not because I want to hear the "Woosh" when I let off the pedal but for more of a positive boost seal especially if the turbos are going to spool faster.

Very nice! I thought you were selling the truck? If not hopefully you make a YouTube video of the install.

My Tacoma sold first so I decided to keep it. There will be a video.

The less cells the better flow. One of my cars had 700 cell stock and I boutght sport cats that are 200 cell, you can even get 50 or 100 cell. More cells equals less flow but if 500 for the RR works then I will be adding them.

Same cats they’re running on their 1000hp Raptor R & SPD includes the midpipe section with their downpipes.

They’ll sound great, hope you love them!

So i reached out to DirtD back in January for the FenFab downpipe setup due to his reputation in the Houston Explorer ST market. They were originally supposed to arrive in about 2 weeks, me Nate kept in pretty constant contact due to following up all the time on the status. After serveral attempts for both of us to get the product Nate came at me with a different plan due to numerous customers backing out a wanting refunds due to thinking he wasn’t doing his best to help out. I think i was the last person to wait approx 6months and he offered me a deal get SPD or taking a refund after consideration it took the refund because i wasnt wanting to spend the SPD money. A few months later i spoke with FENfab and ended up with a set of the pipes. I received them and had fitment issues, got a hold of Nate and he set of SPD made me a great deal for being a solid customer and I took the deal he got them shipped to me and im getting ready to install. Nathan is a stand up guy and will bend over backwards to help out he understands the meaning of business
