Has anyone seen (or heard) of a good compromize on an exhaust system that balances performance with noise level for the TT?

Muffler Bypass pipes on hi flow cats are simply too noisy for street use. Great power, excellent for track I am sure but not for a daily driver.

I am trying to find a set of hi flow mufflers that will mate with my 200 Cel Fabspeed Cats.

I really like the idea of separate cats as opposed to a one piece unit.

Can anyone talk from experience?

Thanks
