Hi-Flow Metal Core Catalytic Converter 63mm
SOLD !
Hi-Flow and Light Weight Catalytic Converter 63mm - Perfect for N/A!
$185 Shipped
or
Trade for 70mm Invidia TP + $110
You ship your TP, pay $110, I ship the cat when I receive your TP
or
You pay $185, I ship the cat, you ship your TP and I refund $75.
$175 Picked up (Downtown LA -weekdays or Costa Mesa -Saturdays)
This is a custom hi-flow, metallic-core catalytic converter. I wanted a higher-flowing metallic-core cat than what was available, so I fabbed my own.
I used an Invidia test pipe and a 200 cpi - made in the USA Vibrant Power catalytic element. If you are familiar with the term "cpi" then skip this:
cpi = cells per inch, lower number means less density and less restriction.
Available S2000 hi-flow cats are 300 cpi which are perfectly good-flowing. I just wanted even less restriction so I used a 200 cpi cat. In my '05, this cat worked flawlessly. No CEL's and no nasty exhaust smell. Fitment was also very good. I've had the cat for about 15 months now. I'm selling it because I'm finally installing the Greddy turbo kit that's been sitting in storage for about a year now, so I'll be fabbing a 70mm Hi-flow cat, the same way, using a 70mm Invidia TP this time.
Yet another benefit, is lighter weight. OEM cats weigh in at ~13 lbs. This one weighs ~5.5 lbs. Saves 7.5 lbs of dead weight! Also as you can see, this cat has heat shields which keep your passenger's feet nice and cool and helps to make it look more OEM
Please note there are two O2 sensor bungs. Only one is needed, the other one is plugged. I used the 2nd one for a wideband sensor I used for monitoring AFR's when I was testing this cat. I wanted to make sure it didn't cause any lean conditions. The OEM O2 sensor will mount perfectly - no issues - practically same location as OEM placement
ALL SALES FINAL
ALL PARTS GUARANTEED TO WORK AND AS SEEN ON THE PICTURES SHOWN
Methods of payment accepted: Confirmed Paypal (I will only ship to Paypal CONFIRMED Addresses) , cash (local

Just buy me lunch or dinner
We can do the install @ Aerosim.
It doesn't take that long
other questions:
I'm not sure, I didn't attempt or measure to see if it would.
However, If you compare the 2 (refer to picture showing cats on scale) it would seem that the OEM cat would fit.
I didn't bother to try it because the metallic cat i used came with a shield that looked "more OEM" than the other cats.

Do you think the OEM heat shield would fit over this?

That's valid question.
CARB and EPA regulations are very strict when it comes to modifying OEM emission devices. The regulations specify that you cannot modify any of the devices that affect emissions, unless they're CARB approved.
According to the regulations, cats cannot be removed or replaced before 50k / 5 yrs (I forget the exact numbers) unless they have been damaged, and they must be replaced with equal or equivalent parts and the reason must be documented. I think all of the HFC's are "illegal" , even though they may in fact perform just as well as the OEM units.
HFC's may allow you to pass a smog test, but if the smog test station has diligent personnel, they should fail you on the visual inspection. Almost all shops will not check to see what particular type of cat your car has. They will only be concerned with the numbers of pollutants out of our exhaust.
I can't confirm that you will pass with this cat or any other HFC, they are supposed to be as good or more efficient that the ceramic type used in OEM applications. I do advice to keep your stock cat handy, swapping it back in case you fail the smog check is fairly easy: Lift car, remove 5 bolts, replace. It can be done in less than 30 min.
