I’m after a cat back system for my SV6. I have looked a lot of threads on this topic but nothing with enough info. The stock system is very quiet and I can only ever hear the engine. I want something that is quiet down low and on start up so it’s possiable to drive early morning and late night so I don’t wake anyone up. But barkey up high with some crackle on back off when I give it some. I’ve looked at different brands like redback, manta, xforce, rhino, ES, DI FILIPPO. Can I get some advice please if you know anything about different SV6 VZ exhaust systems or your experience or if this is even possiable to achieve.
