You've never seen a sexy Hyundai or Honda with a cannon have you? Of course the tip makes a difference to sound, it sounds terrible! The tip of the exhaust on a stock exhaust is a type of muffler, if you change that muffler without changing the exhaust it sounds like absolute shite! Victor said he wants to change the tips, hence going to sound terrible. You can't get aftermarket tips for cheap that are going to sound good, high quality mufflers are expensive. If you're going to spend that money getting a tip welded on and your exhaust extended, you might as well go whole hog and get an amazing quality exhaust that sounds like Pamela Anderson on full scream.
