Just switched from test pipe to highflow...
I just switched out from a helix test pipe to a UR 3" high flow cat. I have a helix exhaust and the thing was loud!!!! After putting in the high flow things are not as loud
Now I have read around that a high flow cat does not rob that much power...around 5whp. I know that this is not even noticeable on the but dyno. But for some reason I can tell a significant difference in power loss. Kinda feels like 15-20 whp on my but dyno. So has anybody out there experienced this or lost alot of power on the dyno by switching to a cat?
Im thinking about running catless again since I feel a substantial loss in power especially up top.

To be a catalytic converter it has to convert something using a catalyst. A test pipe, resonated or not cannot be called a catalytic converter. 
There is only one kind of catalytic converter. If it is a catalytic converter, high flow or not, it will not make the power of a test pipe under any circumstance.
