Muffler Tips on Ebay

Ok I was just wondering are the high flow exaust tips you can buy on ebay ok or are they junk? Here is an example of what I am talking about:

high flow exhaust tips are an oxymoron...
the tips dont do anything to free up horse power or anything
stay away...

but a whole cat back exhaust

I am doing the whole cat back with 2.25 pipes, I just need a tip at the end and I am just wondering does it matter what tip I use at the end?

if youre talking about the muffler, then yes. i would recommend an Apex, HKS, or other high quality brand and it should be fine.

the thing in your link is a muffler, not the tip.
