Just bought my Greddy SP exhaust. I shipped it from NJ to Hawaii, but was unable to get an exact shipping quote from UPS.com. I could only enter the weight and not the dimensions. I informed Ken(buyer) and he assured me that if it came to more when I actually shipped it, he would cover the remaining balance. I took his word and it actually did come to quite a bit more. He immediately sent me the remaining balance. He only has a few posts to his name, but in my dealings, he is and honest and trustworthy person!!!
