Hey guys, I posted a while ago looking for suggestions on what dual exhaust to get for my 2010 silverado crew cab. Well, I ended up going with the mbrp pro series cat back system. I've had it on for a few weeks now, and I'm just not completely satisfied with it. I was hoping it would have been louder. I was looking for something that's really loud and has a nice aggressive tone to it. I don't have a lot of money to spend anymore on it, but is there anything I can do for not too much money to make it louder and give it a nice rumble? Any suggestions are appreciated!
