SakeBomb Garage: 3.5" "Stealth" Twin-Cat with OEM Heat Shield Mounts!
 

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.

Whoa.

Definitely interested to learn more. By "the standard 3" midpipe" do you mean the OEM catted pipe?

That is a nice piece of workmanship. Great idea about allowing use of OEM heat shield. I'd be in but I'm doubtful it would have enough conversion efficiency to pass CA BAR loaded-mode smog test. I bet an idle/2500 RPM test would be no problem though.

I would be all over this if I still had my FD. Finally a nice bolt-on true high flow cat option that doesn’t need to be order from Japan.

Adding my name to this list also :)

Do you guys have a ETA, sorry if I missed it.

Thx, Steve

I'm also highly interested too. Can't stand the stink. I smell like exhaust every time I drive the car. It's too pretty to smell that bad. Y'all gotta get us hooked up!

Have you put these on a flow bench?

Definitely interested. Let me the price and availablilty.

Just to give you my take on this....I think this looks like a great piece for those of us who have gone single and want to retain daily drivability. In my opinion, being able to DD a car is more than just about road manners. If I drive my FD to a client meeting and I smell like exhaust I'm paranoid that someone else can smell it. So I have to keep the windows up whenever I roll up to a stoplight or if I'm starting up or parking the car. That kind of stuff drives me insane. I want to enjoy the car without having 100,000x things to worry about all the time. That being said, all FDs are 25 years or older at this point so it's really just a luxury item that improves the overall experience....aka: a non-necessity. Price point will be a balancing act because of this. Just my opinion.

I'm also curious how this changes the sound of the car. Right now I'm running no cat but I have a resonator welded in. Obviously, this is sort of an "either or" situation.

Expected reliability of the cat cores? I have an SMB and the metal core melted within 10k miles, it's now a midpipe :tonque:

Have you guys done any flow testing?

Any updates on this?
thanks

@ SakeBomb Garage

Any update on this. It's been almost a year since the original post. Did the project get scrapped?

If not, is there pricing? Flow test results?

Depending on price, I am a buyer. I have done the catless route ad it stinks, but I would like something that flows better than my high flow ceramic cat.
