That would be so cool to have factory downpipes that are cat less no reason to take them out for service!

I like the idea. Yes, it's not as high-flowing as aftermarket, but still better than stock. Better chance at retaining warranty, and still keeps the integrity of OEM quality. Very interested in how it turns out.

hate to burst your bubble but no cats on the dp = cel.
its the same as having a aftermarket catless downpipe but at a lower price...
