Jordanvraptor with only the mufflers installed, there will not be any significant hp/tq gains because the stock catback is all corked up to reduce sound. I only replaced my exhaust with the Magnaflow catback system and obtained at least 20+ hp. People including the old timers love the way my car sounds. It's quiet at idle but when you get on it all hell breaks loose. Even the chevy guys break for cover. The exhaust has a crackle/ pop sound to it, but that's the natural sound of the engine releasing that horsepower (she has to breath).:coolman: :coolman:
This with the stock H?
