PTP S63 turbo blanket?

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

I have seen the turbo blanket fit, but I don't know how well it works alone. I have always seen the downpipes wrapped individually first, then covered with the blanket. its much harder to wrap them in the car, so I can see the appeal of the turbo blanket. Also I don't believe the blanket covers underneath the downpipes so you will just be holding the heat in the hot V of the engine, not really reducing the temperatures there. I think the turbo blanket is best used to protect painted engine covers.

you could wrap the cats but that might actually wear your cats out. the increase in internal temperature will become much higher when wrapping the cats, and that could blow them out under certain circumstances. typically downpipes reduce the temps since there is nothing the temperature can latch onto, such as the ceramic monolith.

wrapping a set of downpipes outside the car is very easy though. I have a set of XS-Power downpipes I got for cheap on amazon, that fit perfectly and wrapped in DEI 2" exhaust wrap.

Hmm, maybe individual turbo blankets and then wrapped down pipes is the best route for reduced temps. Does anyone know which size/style turbo blanket would be correct?

I put it on top of the heatshield & I am running DP's. Aftermarket DPs won't hold as much heat as the OEM due to less restriction in exhaust gas flow.

I am using the XS-Power too

From what I understand the turbo blanket is supposed to keep heat in on the hot side of the turbo keeping it hot makes it more efficient

Agreed, but my concern with the blanket is it just sits on top of the turbos/cats, so the heat is still radiating down into the block/heads.

Hi Patchejs, Good question. You would have to ask directly at PTP. Maybe they can say that.

I have the PTP blankets too. PTP told me that it would be better to install without an OEM heatshield
