Hi everyone -- I recently bought a '98 Berlinetta (I'll do a separate intro thread once I have it home) and one of the first things I'd like to tackle on this otherwise beautiful 355 is reducing engine compartment heat. It seems like it'd be pretty easy to mitigate the problem with heat blankets on the exhaust. My car has stock headers and cats and a Fabspeed muffler (that I'd like to replace with a stock muffler, in case anyone wants the Fabspeed). I am probably going to replace the cats right away with aftermarket 200-cell metallic core cats (if you have a pair for sale, please PM me). While doing so my plan is to wrap the cats with 1/2" thick heat blankets and wrap the headers from the union with the cats back to the collector. I would think this alone will substantially reduce engine bay temps. I'm also fabricating heat shields for the trans mounts and improved CV boot shields. This is the heat blanket I was planning on using -- $125 for a 1'x5' roll. It's not Iconel, but it's also not thousands of dollars, and it's pretty effective stuff. https://www.amazon.com/Heatshield-Products-176005-Exhaust-Stainless/dp/B0051UPJIC/ I've been an air-cooled 911 guy for many years and do all my own mechanical work, and the F355 is a dream car, but having almost the entire exhaust system (including cats!) inside the unventilated engine compartment is just asking for trouble. I've done a lot of searching in the archives but haven't seen much about heat mitigation -- would be grateful for any advice or comments from this group that I've learned so much from in reading the archives.
