Whats a good brand of exhaust tips to buy? I found some nice 3 inch chrome slash cut tips at my local pepboys but i figured the chrome would peel off in about a month, where do you guys reccomend I buy from? Also what is a good length of tip to put on our car enough to where the tip doesnt stick far out of the bumper but you cant see much of the weld underneath. I was looking at 18 inch tips, is that too short/long? thanks
