For what you'll likely spend for a nice set of chrome tips alone, you can buy a complete MAC catback. You'll end up with a deeper, more aggressive exhaust note (no freeway drone) and a pair of chrome, 3.5 inch pie-cut exhaust tips for $350 to your door. www.macperformance.com

I'm running a pair of LFP (Bassani) hi-flow catpipes in front of the MAC and it's VERY aggressive soundwise. With the stock cats it's not too loud, but it sounds much better than the stock muffler.
