RB Full Exhaust vs Just Bonez DP
 

So I had a bit of an exhaust leak issue and long story short I drove around for a day with just the Bonez 2.5" DP attached to the car (wide open exhaust!). The next day I installed my new turbo back Racing Beat 3" exhaust (silencer and two mufflers). Which do you think was less restrictive? Apparently it's the RB exhaust! There was no question that there was more power through the rev range with the RB exhaust.

With my monster wastegate port boost was at stock levels with my old exhaust and didn't change with just the DP on. It will actually hit fuel cut in 3rd+ with the RB exhaust. (only just barely though) We've all heard the glowing things about the RB exhaust, but I'll add my 2C as to how incredible it is. The volume is near stock.
