Bassani Axle backs with...
 

I have a black 05 GT with bassani axle back exhaust...thinking of doing the quad tip exhaust as well...

Has anyone ever done a similar set up? How did it work out and was there enough back pressure to notice a difference in sound?

I love the bassanis when I get on the gas but just doesn't turn enough heads when I'm just cruising along....I figured this may help with that issue and will be a little different too.

I have not tried this but I doubt that changing to dual tips will make a big difference in sound.
