Tail pipes

Not to happy were my tail pipes hang.I bought a kit allready made up and the install went good.What i dont like is my tail pipes run along the side of my gas tank and along my shackell,and it hits there and banging off it.I could drop the mufflers down a tad and sure it would be fine,but would it look to low from behind.What do ya yhink.Anyone willing to up load any pics of how far down your tail pipes hang.Thanks.
