Heat shields + Thermal barriers advise needed

Hi

I fitted a 430 exhaust system into my 360 today. It sounded wonderful with a lot more volume to the sound. Low rumble at the lower RPM and OMG at a 6000PRM or above (sounded similar to when the bypass valves are unplugged below).

Attached are some pics of the system and sound bytes

I do need some advise and help from you guys. I think the 430 box being smaller, it does generate more heat than the 360 box. What heat shields + Thermal barriers materials and where should I use to reduce or channel the heat away from the surrounding?

I wanted to stay with OEM products for many reasons so the 430 was the choice.

Most of the work is to alter the exhaust pipes to fit since the 430 exhaust pipes is longer than the 360 pipes. It would take a good muffler shop about 1 day to alter the pipes.

 

I got those from Ebay (a company from UK for $500). These came with screws so you would have to drill a few small holes. It is best to install with the rear bumper off the car.

If you search Ebay for "ferrari diffuser", you will see it.
