You are like a stuck record Eden!
I chose this over the killer-b sump because it's a stock sump that has been gutted... so no concerns about fitment with aftermarket headers.
I also trust their more conventional baffle design over the killer-b design which doesn't appear to be very comprehensive... even though they are
reputed to be very good. The RCM baffles look very close to macbilt baffles, which I also trust... but this was cheaper by a few hundred dollars
including shipping and faster to get by a week... and I didn't need to take the car in to get measured.
