Long tubes. I did the shortys once, and regreted the hell out of it. I just did LTs, and I am a very happy camper, ah er Cobra driver I mean.
Totaly changes the tone. Nice at idle, screams like a rabbit gettin F***** by a Rhino at full Throttle. Gotta love it. Little more money now will make you happy later. You know deep down you want to do LTs........
