Hi peeps i fitted my new HKS hipower exhaust on yesterday it was soooooo easy to fit! when i took my old one off i didnt realise how f**ked it was, it was a combination of Apexi backbox which was 3 inch bore lashed onto a standard 2.5 inch middle section with the cat cut out and it was so rotten i was stabbing holes in it with a screwdriver! Anyway it absolutely sounds the nuts definately sounds alot better than it used to and it looks nice to and it goes better for it as well as the old system was restrictive. Im so happy with it i cant stop driving it!
