How were they designed, to do what purpose? If it wasn't to eliminate the drone - they do, if it wasn't to eliminate the cats - they do whether you have stock exhaust or after market. If these weren't the intent of the build then what was?
True. They work great for what ever your intent.
A little pricey though.
ID say I got a 5% or more, boost in power, and it is noticeable.
They worked for my intent.

I'm surprised the Chinese haven't jumped on this, it would probably be half the price with COLOR instructions.
