i just had to switch from the riss catted to ar catted because the cat actually came loose and was rattling in one of my riss dp's... No bueno i went with ar i should have them in a week ill let you know what i think of them. I also have the riss exhaust which of course didn't fit right with the riss catted dp's.

I've got a Dinan Stage II tune and I'm in the UK where we can't really get away with running catless.
I haven't really given catted DPs a thought but perhaps I should. What are the pros and cons? Are they noisier? Will I really notice a difference in power, response etc? I've got the stock exhaust on at the moment. Would I also have to change the rest of the exhaust? Any advice gratefully received. Cheers Jack |

What is the life of the cats as compared to the stock BMW cats? Should they last as long? Can they be replaced if necessary? Tell me about the ceramic coatings (I've just looked at your website). I'm planning to keep this car for a long time. Are you saying that without the coatings that the pipes will rust? I know Kevin Bird well. I've had lots of work done on my car there - Dinan intercooler, oil cooler, Hartge suspension, Quaife LSD etc etc. Jack |

Should be very similar lifespans. We have yet to have a single reported failure on the cats we currently use. A new set of cats can be welded in, but we do not reccomend it. The pipes are 304 stainless - should not have any rust issues....
