That's a common problem with the racegate. I still use them in twin setups if requested, but I prefer the Turbonetics New-Gen. But it is a very pricey piece. Most people don't need any more flow than a Billet Extreme can provide and if they do or are willing to part with the dough then again back to the Turbonetics. I built 3 sets of twin piping for my own truck (different charger combinations) and everyone of my sets of pipes utilized a Turbonetics New-Gen.
Pricey but nice.
Back to the Racegate. If you can stand the mess then don't worry about it. The leak isn't enough to cause drivability issues or greatly affect the spool up.
