strange backbox
When changing my exhaust the other day i noticed a strange thing above the backbox, id never seen one before there is a weld coming off the pipe and on the there is a closed cylinder type thing(shaped abit like a torpedo) first thing i thought was its a bomb like in the speed movie where i cant go under 60mph or something 
Anyone got any ideas i cant find any on the net, will get a pic up tomorrow night
cheers

What make is the exhaust?
I have seen one type of exhaust like this. I think it was a HKS with the torpedo shaped thing you mention. Not sure what it does though.

Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated applications. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.
For turbocharged applications, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles also benefit from greater exhaust flow capacity as engine tuning levels increase. Certain applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler. Like Drager Exhaust systems, Hi-Power Exhaust systems are made from SUS304 stainless steel muffler and tip assemblies
