I have a 2006 Volvo XC90 V8 turbo, has 129k miles and all I have done to it is get a straight pipe from the cats back but it doesn’t sound like everyone else’s can someone point me to where I have done something wrong or maybe there’s a problem with my car. If you search 2006 Volvo XC90 v8 straight pipe there’s 100s of videos and they sound insanely good, mine sounds nothing like it. Please if anyone has any suggestions.
