How about a ROM tune for OBD II? lol :eek::biggrin:

Oh and a side note, my rear bank cats are rattling against the rear sway bar which is the daily 0.875" one..... :(

Nothing for OBD II yet sorry! But we can get you either an AEM EMS or FIC! :smile:

Bring the car by and let me take a look at the rattling. That's the first i've heard of that problem. I'll do my best to resolve it for you.

If you haven't heard the difference between the OEM cats vs our Hi-flow cats check out the video below!

UPDATE

We are introducing a new line of high end Prospeed cats for the NSX.

PROSPEED PRESTIGE High Performance Catalytic Converters!!

The Prospeed Prestige line will come standard with our top of the line 200 cell core catalytic converters and is 100% fully polished and give that long lasting high end look you expect for your NSX. This is the best and only production 200 cell Hi-flow cats for the NSX. Perfect for those with a CTSC or SOS hi-boost superchargers.

The cost is $675 for the pair.

If you wish to have just the long lasting high polish look it will be an additional $45 to the cost of the standard 300 cell Prospeed Hi-flow cats. Well worth it! They're stunning in person. PM me for more information on this service.

PROSPEED PRESTIGE 100 CELL SPORT CATS FOR THE NSX!

We have expanded our new line for Prospeed Prestige High Performance Sport Cats! We now offer a 100 cell Sport Cat for the NSX. This is ideal for anyone looking to maximize performance for their Naturally Aspirated or Forced Induction NSX. Perfect for the Supercharged NSX looking to squeeze as much HP as possible without the compromise.

The set below is for the 91-94 NSX.

-Approx. 13 lbs weight loss over factory Catalytic Converters
-highest flowing catalytic converter on the market for the NSX.
-Cores are made in the USA and everything is built on site in the USA.
-All Prospeed Prestige line Sport Cats come high polished for long lasting look and corrosion resistance.
-Built for Aggressive NA and/or (Stroked engines 3.3-3.8) and Supercharged NSX's (CTSC/SoS/Bosch,etc)

PM me for pricing and details.

I see you have a New 200 core.
Do I have to be concerned about my OLD 200 core at all?
I am running them with the Old Whipple on high boost.
Thanks
Trev
p.s. I am still very happy with the product!
 
No one needs anything really....... but we like to buy and replace stuff!!!
If you bought the 200 core, then you have the best flowing cat he had back then.
If you bought the 300 or 400 core, they are a little tighter and don't flow as easy, but do a better job in cleaning up our atmosphere.
All cores will work with your FI, but we like to think the less restriction the better.
That statement isn't always true for drive-ability and power.
Just my thoughts.

I have completed the install of my very shiny polished 300 cell cats. They look and work great! I highly recommend them!
Now I just need to get my ECU out to Brian so I can maximize my TopSpeed Header, Prospeed highflow cat, Dali Wishuponastar exhaust setup!!! :smile:

Thanks Trev, I agree with what you said above Trev. The 200 cell cores you have are fine. I now offer a 100 cell more which is the closest thing to a test pipe without the negatives of them. Do you have emissions in your area? Have you tried to pass your car with the whipple and the 200 cell cores?


Dhalsim,

Congrats on going FI! The 300 cell cats will work fine however the new 200 cell and 100 cell cores flow a lot more! FI cars will see greater gains from a freer flowing exhaust sytem period. You should see hp gains over the OEM cats and the 300 cell cores even. You can always sell your 300 cell and step up to the 200 or 100 cell setup.

Nh_NSX,

Thanks! I'm glad you were happy with the product!
 
We don't have emissions testing here in Alberta but I dislike the smell of the byproducts of combustion, so I choose to run Catz instead of test pipes.
Plus the weight savings....lol.
Thanks

You're lucky Trev not to have emissions up there in Alberta! California is crazy strict!

I also never liked the black soot on my rear bumper and raspiness sound my exhaust makes with a test-pipe on my other cars. Been happy with high flow cats ever since! Plus we got to go green and save the planet! hehe
 
What cats can you recomend for the best performance and how would they compare to a decat/test pipe?

For both performance and sound.
