1. Very clean install - exhaust and switch. Had I not gone with the V. exhaust this was my exact plan - cut outs and black tips. Thanks for all the pics, documentation and dyno run!

2. It is not all all surprising to see such small gains on the dynao. The OEM exhaust is very well optimized from a major OEM supplier. They don't leave much on the table. Of course other systems will leave a lot more on the table to be gained by cut outs.
