Mr.Al

Have driven both the 996 and 997 TT's Remember the sounds of the turbos spooling more in the 996 vs the 997. Is it my imagination or is their a tech reason...both are stock.?

I have noticed the 997TT doesn't have that traditional spooling sound as well. Probably due to the VTG Turbochargers and different exhaust tuning on the 997s.

Mr.Al

Think a Europipe will help???

oh yes! I installed my EP about a month ago and the turbo whistle is very noticeable. you basically can't hear it at all with the stock set up

Mr.Al

Which EP did you install? Want to do it yesterday but worried about voiding my COP...2007 997TT. Which TT did you install on??? Thanks....was kinda dissapointed cause the "spooling" was addictive.

I have the EP1, installed in my 2007 997.1TT. Both the EP1 and EP2 use 100 cel cats which really frees up the exhaust flow and spins those turbos!

wouldn't worry too much about an aftermarket exhaust voiding your CPO but definitely check with your dealership before moving forward

Mr.Al

aa909...Thanks a million!
