My kit is the final finish product with the 34 - 2 tooth "chopper wheel". You have the option to either keep the OEM CAS or use a blanking plate. I kept it for ease of starting. The first versions had 12 teeth without a missing tooth.
Why not get someone like Hypertune (or any half decent fabricator) to make you up a new pipe. Would look much better than joiners and clamps every 15 mm.
Not really mate. I just don't really drive it over Xmas for a few reasons.
1- not good to drink and drive haha. (Xmas beers... Mmmm)
2 - it's too Fkn hot.
3- too many swines on the road plus Double Demerits.
