Hi guys, still relatively new to this site. I'm a bit of a noob when it comes to this kind of stuff but I couldn't find anything specific to my enquiry. I have a 2010 berlina, 3.0L sidi. I've made it look nicer than the grandma spec it comes stock. Been lowered, tinted windows, Calais tail lights and front bumper And chrome twin tips on both mufflers. The only thing wrong with it is that it sounds just wrong. Has absolutely no sound to it. Need it to sound like it looks. I'm not looking for performance enhancing or anything ridiculous (any performance is a bonus), simply after a bit of nice sound to the exhaust and not wanting to end up with the infamous droning sound. I know it's a V6 3.0L and some would question why I would want such thing. I'm not here for opinions, I'm here for advice. What size exhaust comes stock on my car, and what size should I get? Will it require a different size fitting if I go bigger or can it just be bolted straight on. After a cat back replacement, nothing like headers/extractors whatever. Brands to lean towards/avoid? Thanks so much in advance for taking the time, and sorry for such a long post.
