RJP 951

Hard to tell but that looks similar to the ports on the cycling valve. It's in the same general area, at least. Is your CV disconnected?

Thanks, I verified in the factory manuals that the valve without the tubes is the "timing valve" which I guess is the same as the cycling valve. I thought (or hoped!) that was the answer to my problem but nope.

Just an update for reference... I had the car at the shop today and we measured the temp of the exhaust pipes before and after the cat. Warming the car up for a couple minutes produced a temperature over 100 degrees hotter at the inlet before the cat vs. the outlet pipe after the cat. Therefore the cat appears non-functioning and partially plugged.

Although the car failed the emissions test across the board this time, it has had a high NO ppm number for the past couple years. This may indicate high combustion temps due to a failing cat. (This was even before I installed non-stock chips which raise the timing.)

Over the past couple weeks the coolant temp has started increasing more than normal too.

The space provided for the cat or its replacement is pretty tight and the stock cat is rather long so we elected to not try to install a universal replacement in there.

So... I just ordered the SFR 3" test pipe with optional cat section. In the next couple weeks, I should have the product and have it installed. The shop has a dyno so I am considering running the car with and without the cat to see the hp difference.

Thanks all for the info!

I may be wrong here but isn't the 3" testpipe and cat the exact same system that is supposedly manufactured and sold by Fabspeed?

Just curious.

The testpipe on Fabspeeds' website does look like my SFR pipe.

However, the cat-back on their website looks nothing like my SFR setup.

Whoever made mine I care not, I love it.
