i got a 2.5in custom exhaust done on my da, the shop used a flow master muffler and i hate the sound of it. My friend has the same setup with an es oval but i cant get one anywhere because they have been back ordered for months, i was wondering if anyone knows how the magna flow ovals sound? thanks for any help

 

add a resonator to the piping

 

and that will fix the tingy nasty sound?

 

It would make it sound a bit more dull and quite.
