I just finished this install. I went from a complete stock set-up to a complete Tubi set-up. I really don't know if there is a performance gain. However, it does seem to get rid of that slight hesitation around 5K RPM...seems like the car revs much more freely. Having said that...I did not just do mufflers first...so I am not sure what portion of the upgrade contributed to that feeling. Bottom line...is it sounds much better and there may be a SLIGHT power gain.
