    Default Dual Exhaust - No Back Boxes?

    Hey all!

    I've just gotten my new Dual exhaust system fitted by Longlife.

    Full stainless steel Cat-Back system, with dual tips (looks like 2 pipes either side)

    looks great, sounds great and improve the responsiveness and accelleration of the car - bonus!

    However, it does seem to sound a liiiiitle bit hollow, probably because they decided to only use the centre box and remove both back boxes. Which they said they've done to improve the sound.

    I was just wondering if anybody else has had a stainless steel system fitted to their veccys, and did your company decide to forgo the back box and just use a long pipe from the centre box to the rear? if so, how does yours sound? good? a little hollow?
