Thanks for your replies. I've heard a number of Pagodas in the past and mine is much louder especially at speed. I understand the cautions but, as at least an intermediate step, I'm going install the good Eberspacher I have in the system and cross my fingers. Bora East had a resonator in stock to replace the one I had and it did make a small difference. I'll keep you all posted.
Just understand that anything made by "Borla" will be louder by design. Louder than stock, and louder than other systems. That's their MO. While some systems such as the OEM or a TimeValve only have ONE system, Borla has three dB levels: loud, louder and loudest. They go by their names of Touring, S-Type, and ATAK. They also have a race-only system called XR-1.
Good luck and report back on how it all fits together for you.
Doesn't apply to you, but in North Carolina any modification to a street-legal vehicle's exhaust system to make it louder than the OEM stock system is prohibited. Doesn't stop all the wannabe NASCAR drivers with their exceedingly loud cars here. Police have more things to worry about and loud cars persist.
