anyone know which mufflers sound the best as far as making it higher pitched sound?

the car has an rps header (2jzgte swap) and I need to complete the exhaust system. I bought a pair of aero turbine mufflers but the car is still pretty loud (4" dp/mp exhaust) and was wondering what else I can go with to possibly quiet down the volume but also make the sound quality and performance still nice (don't want to restrict it too much since it has a 4" dp/mp)

thanks

 

go on the exhaust thread in the performance sub forum

 

thank you!
