RB-Tech cat back, Does anyone make high flow cats to go with the cat back?

With the RB-Tech cat back you keep the factory cats.... Just wondering if there is a High flow cat I can use instead.... Or can i run a 99 430 with out cats? I mean will the computer go crazy and shut the car down?

If you remove your cats, your check engine light will go off. MKB makes a dummy sensor to trick the car into thinking that the cats are still there.

Also running no cats will this help the power....

Their webpage is in German, www.mkb-tuning.de. We carry their full range of performance products. Their cats will increase power, however for the price, you may rather spend a little more and upgrade your rear differential.<br> <br> Running no cats may increase horsepower, but will reduce backpressure, and likely hurt torque. I've seen a CLK55 dyno'd with the cats removed that has lost power due to the loss in backpressure.
