Catalytic converter replacement options
#31
Another thing I noticed when I switched over (and this could just be because again mine were clogged) was that it takes a little higher RPM to launch the car. So it almost feels as if the car lost a touch of low end torque when I upgraded. But it does feel more powerful at higher RPMs than before. Just an observation though, don't have any before and after numbers to back it up.

If there hasn't been a CEL with a converter error code (P0420, P0430 to list 2) I'd hazard a guess -- no bet though! -- the noise is *not* from the converters.
My 02 Boxster had a buzz and while I hoped it was just a heat shield it proved to be a converter.
However, I hoped against the odds as my car's converter, the loose one, every once in a great while would trigger a P0430. What would happen is the loose brick - the source of the noise -- would shift out of position slightly and this would affect the exhaust flow through the brick and the CEL would come on and I'd pull the P0430 error code.
As long as the engine runs ok, as long as the CEL stays dark (and if it does come on offers up an error code that points to a bad converter) you might just take a wait and see attitude. I drove my Boxster with the converter problem quite a few years, but the car always managed to pass emissions testing, though this last time took some extra effort.

I have had resonators removed on an '03 VR6 Jetta and an '09 2.0T Jetta by the same local shop and they had to fabricate a bent pipe to replace the resonator on the 2.0T. I have been very pleased with their work on those two cars and would trust them to do the Cayman.

That being said, has anybody here in the 996 forum purchased aftermarket high-flow cats and taken the factory cats to a reputable fab shop and had them cut out the factory cats and replace them with the after market CATs?

I purchased CARB-legal cats by Magnaflow, direct bolt-on (no fab/weld/cut needed). Also had bungs for O2 sensors.

Thanks for the reply. Have you had them on for a while and no issues or CELs? They do have those Maganaflow bolt ons for the Cayman at about $400 a piece. Of course then I'd have to pay to have them installed too. I read a post from one guy that said it should only cost about $500 to have a couple hi flow CATs welded in place of the OEMs at an exhaust shop and thought that might be a good way to go since the CATs by themselves are less than $100.

Bought the cats from HOTTEXHAUST.COM (free shipping, authorized dealer). Ask for a 10% discount coupon (saved over $200 for both). Best of luck.

Magnaflow requires installation by a shop to keep the warranty. My local indy charged $145 (passenger side) and $200 (driver side).

I did some research on a mfg number I found on some cats offered by various companies and found the company that makes them.

I know the name sounds shady, but I've used them on three different P- cars now and they are great.
Roughly $340.00 per side shipped.
