Just wondering who has the best quality stainless or chrome extension for a 6.0
and what size 3.5?
The last one I had on my 03 got dull right away.
2005 X stock exhaust

 

There are some good options to go with. If you want the extension (Exhaust Tip) to retain it's shiny appearance, you would really have to go with polished Stainless Steel. T304SS is the most heat treated of the different types of stainless, T409SS is the next best. And, OEM's simply use "Aluminized Steel", which is good quality to hold off rust and such, but not real pretty and it oxidizes fast. There are some really nice T304SS tips from Silverline, with many styles. MBRP also has a good selection. I believe you would need to find on that is 3.5 inches on the connection side, and there should be a selection to choose from for the end of the tip (5 inch or 6 possible)
