I recently did some exhaust mods and I have been getting a lot of people commenting on the sound of my car.
I used to have a full genie system (stainless extractors, and 2.5" mandrel bent single system)
Now I have jet hot coated big bore pacemakers, supercats and the genie 2.5" mandrel bent SS system.
If you want to get an idea on what mods you can do, and the power you can expect... have a look at my web page. Under the "My XR8" page - there is a full list of mods, dyno charts and mpg's.
