Yessir. It's quite stout as is. More is always better though.... If I still have it at 60k miles, after the warranty is up I might throw a down pipe in and a Cobb tune (when available) -that shit would be noticable.
I had it installed last week and it's a little underwhelming.
although it does improve shift points and slightly better throttle response it does NOTHING on the bottom end. the tune is only noticeable 40 mph and up.
