First off, the stainless steel shield is well-engineered and is doing its job! After my cat was stolen less than 6 hrs after it was replaced (thanks Bay Area), I decided it was worth getting the stainless steel shield upgrade. Almost a week in and I still have my cat, so great deterrent and no regrets. I appreciate the thoughtful design, which doesn't require drilling into the frame and is compact while still protecting the cat from all angles. Also, save yourself some headache, and just plan on replacing your 2 rubber exhaust hangers (as the instructions suggest).
Second, a huge shout-out to Miller Cat! Their customer service is fantastic, and they went above and beyond when I had an unusual issue with one of my screws. They were super responsive, helped with my install, and even followed-up with my mechanic to explain what happened. So I highly recommend both the shield and the company.
Stainless Steel MILLERCAT 2004-2009 Prius Gen 2 Cat Shield™ Complete Package
I have used several other brands for the Prius Gen 2, this Stainless Steel with Best Screws version is the best so far. It is well design and fits perfectly with no modification required as experienced on a 2008 Prius Base model. No drilling is required which is very impressive. Here are a few notes I would like to share. Best to a 13" long handle nut setter. The front OEM plastic shield need not be reinstalled. Do not use power drivers on the plastic OEM nuts or the Key Bit for the security screws and nuts. Definitely change the 2 rubber exhaust pipe hangers. In my application which is a 2008 Prius base, it did have the issue where the cat would bump into the shield upon acceleration. In addition to their trouble shooting guide, there are several ways to remedy that: 1- space the 4 couplers farther from the body of the car. and 2- add spacer between the shield and the coupler which will require longer screws or 3- replace the 2 hangers but hook it (HOLE to center of the hanger) so it will take the CAT up so there is 1.5" of clearance. FYI, new hangers that are not OEM are often longer (Hole to Hole) by about 1/8" such as those sold at Autozone. Or replace the hanger sold by Catshield or get Toyota OEM or get one that has 4 holes for multi position use. From experimenting, 1.5" clearance will give it a good margin.
Great piece of material. Good communication throughout and delivered as promised. No hesitation in recommending. Installed by Toyota Dealership
It rattles. I’ve had the mechanics who installed it look at it twice. It appears to be a problem with the design of the plate not allowing sufficient room and so it rattles. It was more expensive than other shields which is why I bought
it. I didn’t want to have to deal with problems from it. I contacted Millercat and they recommended the screws be torqued down more, which we did and it made the noise worse likely because of the lack of space. I do not recommend others purchase this item.
The exhaust hangers were replaced as well.
