Can the Cats be wrapped to reduce heat?

[ZOOMBI U]

Does anyone have any experience with wrapping the cats to reduce (restrict)heat, or will it restrict air flow and cause other problems?

the answer to your question is yes. but you should consider using high flow cats & wraping them.

Just remove the cats and reduce ALL the heat It adds HP too.

Appox. 1 year ago I converted my GTS to Gen1 side exhaust. I stayed with the factory cats and used aftermarket mufflers. I wrapped the cats and the mufflers with aluminized asbestos-like cloth. I left both ends open for heat escape. To date, I have had no problems and I live where it REALLY gets hot. I used a infra red thermometer on my side sills the other day (ambient temp 105F ) and over the cats it was 160F, over the muffler it was 110F and the side pipe was 365F. I can't speak for others, but I am pleased with my results. I have all fresh paint on the side sills and wanted to protect it.

How hard are the cats to remove on a 97 GTS? Are there o2 sensor issues?

I wrapped mine in butcher paper and threw them in the corner of the garage. Much cooler.

Shelby, how do you get through our TX inspections with no cats?

Sawsall to remove cats and mig welder to replace with straight pipe. And no, a 97 will not have o2 issues.
