My 04 996tt has FVD cat back exhaust and ECU flash for about 525 hp, my mechanic insists I should shield and or wrap the cats to protect motor from heat, anyone with info or experience? Thanks MP

 

do you have a dyno sheet showing that? Id like to see it if you got one.

 

FVD has their tuning dyno sheets on their website.

They tune to 490 HP (tune only) on a base turbo. Here's the dyno sheet:

For the X50, they tune to 510HP (tune only). And here's the dyno sheet for the X50 tune:

Undoubtedly with other mods, like an exhaust, these numbers go up.

 

i was hoping for a before and after dyno run sheet. no worries.

 

no dyno info just claimed by EMW flash programmer, seems accurate makes a huge difference just wondered about heat shield etc.for cats, is this legitimate concern ?
