Best high flow cats?
I currently have primary and secondary cats deleted on my E55 and the smell is pretty bad where I cant even idle/drive with my windows open so I want to put some high flow cats in the primary location. I have been doing some research and found thunderbolt 3" cats from performance curve but they canceled my order because they cant sell to CA residents. Any other good cats out there?

i don't believe the W211 E55 has been put on the list this year for use of non factory catalytic converters as a replacement. best advise is look for a set of good used ones if you're looking to return to OEM.
if you want high flow, pretty much all but HJS high flow's are similar. similar in meaning reviews of them online state they blow out. on my 4 cylinder audi turbo it seems that the aftermarket high flow cat i have is a Magnaflow 200 cell unit. been running great for 4 years.
