Yer, the other system I am looking at is FUEL, the Titanium coloured version.
Here is a link to both Exhausts for you to take a look at. The FUEL Exhausts have a great price and good feedback. The Two Brothers seem to be very good, but im lacking any info from people who actually have them, they are a US company so they are a little more expensive.
