I have seen this numerous times about what should be done about the cats and the alternatives that people have been trying to come up with. Today I got on Brenspeeds website. I had them install my ceramic cat before I was supercharged b/c at the time i didnt think I was going to get a supercharger. Well here I am with a saleen and those dreadfull cats.

So anyway I found the two different types of cats. One being ceramic which I believe to be the most common as its a cheaper cat. This is also not made for supercharger applications

The metallic cat is made for supercharger or turbo applications. The brand that brenspeed sells are the pypes. Its a bit more expensive but they are probably the answer to those with FI.

Some of the threads I have read about clogged cats Im assuming are from the ceramic cats and not metallic. Not sure if that was clarified in those particular threads but I believe this to be the common threat of clogged cats (ceramic)

Hope this helps

So when are you taking yours out? I bought mine from brenspeed too. They are gone and for sale.

The easiest solution is to delete them....then you won't have to worry about what clogs...

changing mine to the metallics tomorrow along with installing A/F gauge. I should be about done with the build. just need some DR's for the track and im set

Thats a solution but I think people I have just been ordering the cheapest cat and putting them on there cars with FI when in fact it does make a difference which ones u have on there for FI

Glad to hear your getting rid of them. Jim at JDM told me I had about 6 months before they would melt. I waited a couple of weeks. LOL

I cant imagine running my car without ET streets. Those tires hook so good. Running on street tires seems it would be dangerous with all the power we have. I am already spinning all over the road before I even hit full throttle.

Yea im ordering the silver bullit package from brenspeed for I believe 649 plus 14.99 shipping. Comes with 17inch rims and ET streets.

I have never been to the track just on my regular street tires. Nor would I ever. My car is a beast when I want it to be but is for sure a good DD. I remember asking questions on this forum about my gear ratio and a twin screw supercharger. Couple of guys were telling me I wouldnt be able to handle the power and the car would be a terrible DD. Well that is certainly not the case. i love what I have done to it. I need to get all my receipts and add everything up and see how much money I have stuffed into this car.

Id suspect that they are ceramic but u should just email the with the part number of that package and ask. I take it your going FI if so I would definetly get an answer

Eventually, right now I'm just slowly building up a few things before I drop the big money (exhaust, little suspension work, brakes). I just don't want to have to replace them in a year or so when I'll be putting a blower on and I'd like to keep the cats so I don't have a problem with emissions.

I'll send AM a message and if I don't get an answer there I'll see if I can contact kooks. I'll let everyone know when I get an answer.
