Has anyone installed these with factory cats/heat shield (or catless DPs)? I'm looking at all options to reduce under hood temps. The PTP blanket was looks like it was designed to fit factory cats, I am assuming it all fits with the factory shields, etc. I still haven't decided on catless DP or not, a bit concerned that if I put the blanket on the cats and then decide later to go with DPs, the blanket is going to be fragile from the heat cycles and I'm not going to be able to remove it and reuse it.

I'm also a bit concerned that the blanket is going to essentially hold the heat between the cats and the top of the block in the back, more so than with the factory shielding. I'm trying to reduce the amount of heat back there... Are DPs my only way to go here? Thanks
