Have others who have used the after market downpipes installed heat protection such as ceramic coating, thermal blankets or hand made heat shields? The exhaust area seems to be running much hotter to the touch under normal driving. Comparing my 10 9-3 AWD to the Vector. Installed Genuine Saab 3" downpipe on my 03 Vector. Had flanges made up on cat back and downpipe for future catback mods. Installed BCB Stage II tune with Air Injection and Exhaust Gas Temp delete. I re-installed the upper factory heat shield and did nothing else relative to heat shields.
