ATR Race Cat

Anyone here used one of these? I need a good cat for my 3" ATR downpipe. I have the test-pipe/dump now.
Thanks

There is no such thing as a "race" cat since a cat and race gas don't mix. Buy a cat that has low backpressure if you are going to use one day to day, but the best thing you can do is take it off before you try to go fast. A $60 cat will get you to pass emissions...

Just quoting the verbage "Race Cat " used on the ATR site.
False advertising heheheh

I don't plan to use the cat at the track for obvious reasons. Need it to get the car inspected and for emissions.

Thought this would be the best way to go since I have a 3" ATR downpipe.

If you are using the cat just to pass the emissions test, and you live in an area that uses a dynomometer to test emissions, IMHO, I would not use just a plain old two way cat. You should use a three-way cat. The difference is that the three way cat has a separate bed or chamber use for the control of NOx. The three-way cat can control up to 1800 ppm of NOx, almost more that your EGR valve can control. ATRs high flow cat that accompanies their down pipe is a a three-way cat. It is kind of pricey if all you need is the cat. You may be able to price check some or all of the vendors, or maybe get one used from a board member. If you want to weld a flange on a 2 1/2 inch high flow cat, I'll sell you my old one for cheap. works great and no broken substrate material.

Find a cat the will fit the length you want. Anyone will do just take it to a muffler shop and get the hole enlarged. Most cats out there are between 2 1/4"-2 1/2".

TurboV6--Can muffler shops enlarge the 2.25/2.50" pipe or do they cut it off and replace with a 3"?

You could check out mufflertech.com. That is where I bought my 3" cat. I think it was under $60.00. HTH Rich
