ok, so I went and bought me one of them stainless steel systems with them twirly wotsits in the silencers can't say for sure if it's done any good yet as it's only been on there for about 150 miles, but there is a little more torque at the bottom end nice and quite plus lifetime guarantee for the life of the system, even if I sell the car
2 hours to make from scratch, and looks lovely :)
due to a rodent problem though, no pics will be posted until tomorrow (possibly of some dead rodents, but you'll only see them in the reflection of the exhaust :) )
