i emailed brenspeed for down pipes and cats they said that i should go with metalic cats instead of high flow cats whats the difference? they also said that they could put something together for me so i can have the prochamber with new down pipes there great there

 

i can't help you, but how is that K member and torque limiter setup workin out for you? can you actually powershift now? hahaha

 

The metallic converters have a catalyst matrix made of platinum and other metals, where as the other high flow converters have a catalyst matrix made of type of ceramic.

I think...

Someone correct me if I'm wrong.

 

so whats the biggest diff will it sound better with the metalic cats
