center section didn't work!
Center section melted, broke and cracked after only 20 minutes or so, those mufflers melted on the inside and the 2 bolt flange didn't hold as the bolt would loosen up because of the difference of thermal dilation. The only way you can connect a piece of stainless to aluminum is through a vband flange. we kept the rear section which is basically just an aluminum pipe and replaced the center section with one we made out of stainless. The only muffler we have is a 5" round magnaflow resonator so it is LOUD but on a race car we didn't really mind. I wouldn't run it in the street though, unless you have a turbo to cut the sound a little.
so it is heavier than what we anticipated at first but at least we kept the rear section. i suppose making a catback out of aluminum should work but forget about those mufflers and use a vband.
