Bro g221,
Are there any obvious improvements after using it?
How well is it?

 

[G221]

yes...obvious in sound...not sure on how well the improvement is as installed it together with other stuff..but for sure improvement is there. if not people dun change extractors/headers. go dyno and you'll know.
