After market exhausts

was reading some articles on the performance pickup by adding some of the higher end after market exhausts. like example this high performance one made by Meirnschaft (sp?) is claiming that on the prior M3 the HP was boosted by 10 to 15%. doesn't that sound like a lot just by changing an exhaust system?

what are folks here thinking - after market exhaust or stick with the factory version?
