We hope you all have been keeping busy in the garage during these odd times. We've both been extremely busy trying to get back to everyone's emails, questions, and fulfilling orders... why trying to take some time to tie up loose ends on projects we've had in the works for some time now! We figured it would be a good time to show you guys what we've been up to...

Introducing the SakeBomb Garage 3.5" In/Out "Stealth" Twin-Cat with OEM Heat Shield Mounts! Our goal was to create a catted mid-pipe that flowed nearly as well as a mid-pipe. Our goal was a fast light-off, long life, and ability to withstand abuse. In order to accomplish this we started by splitting the exhaust flow into two, to reduce the thermal load on each cat by 1/2. We utilized TWO 200cpi metallic-substrate cats which can take more abuse and heat than a ceramic core, and flow much better, while having double the ability to scrub exhaust. We also created a reverse-compatible flange that works with a 3" or 3.5" downpipes and mufflers (coming soon ). We have incorporated mounts to attach the OEM heat shields, for additional thermal management and a very OEM-Look . We've also included an air injection pump tube, with block off flange if your air pump has been deleted.










More details, price, and dyno results to come shortly. We will be comparing flow to the standard 3" midpipe as a benchmark.

If you're interested, please add your name below. We'd love to hear your thoughts and comments.

Nice looking piece...can you weigh the stocker and your mil,piece just for weight reduction comparison as well?

I'm very interested to see how this piece compares to a straight pipe. I would love add a cat to my car so it smells less like a lawn mower. Curious the price point as well.

Haha - using the stock heat shields is a nice touch, but all that large diameter stainless with nice looking welds is anything but OEM looking; probably won't fool many smog techs with this one.

I've actually been considering having something like this custom made for a while (I would only do 3" piping, but otherwise similar). Might be interested depending on cost; this would make a good "in between smog checks" cat converter.

Looks like a very nice piece for those that need to run a cat. Even better is the factory heat shield fits.

 

Hey! I'm highly interested in this, if you want to test this out, i'll lend over my FD

salt bath the visible parts to induce a nice surface rust look haha

is there another thread about this? I'm sure I posted asking about expected reliability/longevity of the metallic cores as my personal experience with an SMB unit is that it melted within 10k miles...

 

Yeah, if I do a custom exhaust I was planning to cover it with mild steel "heat shields" and let them rust a bit.

Looks like there's another thread in the 3rd Gen group buy section

def interested in replacing my bonez cat as that ish stinks! lol. The idea behind splitting into two cats is pretty smart. Would love to see more info and tests!

 

Interested because I'm tired of the catless smell, but looking for tests to be completed and more info. I'm having a difficult time grasping how the thermal load is cut in half if the same temps will be entering the parallel cats. Maybe I'm overthinking this. Any thermal engineers able to pipe in?

Interesting. Although I don't have a rotary in any of mine anymore, I would have interest if the cats are HJS.

 

Interested (depends on the price as well)
