I would suggest going with the Blastin bobs exhaust like
[email protected] was referring to. I have the 2.7 and I had the MAgnaflow dual exhaust with quad tips on it. It was fine, but I just didnt like the tips. Well I changed the tips on it to Borla 5" tips and man it looks good, but i think it is too loud for my taste. With the blastin bobs, it is very cheap (compared to the magnaflow which is like 900 bucks) and will give you good sound. They also provide you with the cutout templates so that they will fit into the bumper to make it look more factory. Check it out, there are plenty of exhaust options out there, it just depends if you want to spend alot or a little.
