Does anyone know of any companies developing or selling catless downpipes? With the recent changes at the EPA, I would think that we may start seeing catless systems again? Should be significantly less expensive since you wont' need two cats anymore.
They are typically far less expensive but some of the new high-flow cats are really good. I put sport cats on one of my other vehicles and they flow over 90% what a non-catted version would. Plus no smell. But again, good cats are costly. The SPD cats for the Raptor actually aren't a bad deal at all, less than half what they are for many sports cars.
