Default What do you recommend for hi flow cat Stromung or Random?

I just realized that Stromung make a bolt on hi flow cat. I have a borla header and a Stromung mid pipe. Would you go with Random tec. cat, or the Stromung. I kinda leaning towards Stromung.

Haven't heard anything yet about the new Stromung but I have heard of people having problem with chunks of the convertor's core breaking loose and rattling around in the cat housing after a relatively short usage period (1.5-2 years).

one could look into a performance muffler shop, I think they have flowmaster and borla "universal" high flow cats. Just an idea. I think they run about 80-140 for the cat, then about 50-80 for install.. due to cutting and welding

I got a catco hi-flow cat for about $54, then another $90 for install. Could have found a cheaper shop but this shop does great work. Still only half the cost of a Random Tech.
