I had my sti03 ppp'd about a month ago. When i first collected it the exhaust was very loud and i drove it with the rear windows open just to enjoy.

Now, i barely notice the exhaust plus the performance seems to have dropped. i am pretty sure that i have not just 'got used to it'. Is there a problem, perhaps the two are related? Any comments?

Thanks.

 

DE-CAAAAAAAAAAAT,not very helpful i know,but will make some great noise!!

performance dropped!!!!! pop it back!!

goodluk

 

maybe you have gone deaf!

 

Wish i was deaf but i can still here the wife!!

Definitely used to be a rasping sound,now seems just like pre ppp. i even checked to see it said prodrive on the exhaust in case someone had swapped it!!!

Performance is very disappointing, i am losing interest in scoobys or maybe its turbos in general, previously owned wrx + RB5 Prodrive with decat and induction- that was a lot quicker off the mark.

 

Exhaust leakage?
