Challenge, tubi or straight through pipes?

[adi]

It seems I have 3 options for replacing the heavy, quiet twin backbox & cat setup in my 348ts.

I know a tubi sounds good, know nothing about the challenge exhaust sound and fear the straight through pipes may be a little 'too' loud. I am not tracking the car, just want to hear that engine a bit more... has anyone had experience with any of these setups? Cheers

Manu,

Fantastic response - just what I needed to know...

I'll ring you tommorow to discuss the full bypass system - assuming there is a way round the emissions issue, I think I am most interested in this option (you are a good salesman! )
