My lawnmower runs at 20 BHP which means that the muffler gaining 10-15 horses isn't very noticeable at all. You may notice more torque and throttle if you added the chip for 20 more horses = 30-35 horses more from the stock

But I just love the way it sounded compared with the very refined stock sound. And I kept the stock muffler in case I wanna put it back to its original set-up...for $60 bucks

If Borla comes out better with more HP increase>30-35 HP, then I'll replace it with Borla..if the sound is right

Right now, I was just trying to enjoy more of my XFIREX Might get some of those interior blue neon lights installed from Circuit City like Boba

My wishlist....if AVIC N1 will come out with the silver trim
