Ok theres the inside of the new tips..and my questioning was that it didnt look like those two little screws could hold on the entire exhaust tip. Am i going to have to do what az96ssei did and have a welder weld them on? Does anyone have any comments or suggestions?

I would suggest taking the screws out and have them weld it on to the factory exhaust pipe. This way they will probably sound beeter and you would have a sealed exhaust. Just my .02.
