Thank you for your post. I will give you my opinion on the exhaust. I did a lot of listening and looking and decided to go with the flow master 40 series muffler only. The sound is just right not over powering down the road but I nice rumble on a normal start and a roar if you really get on it.
IMO, it was worth the $$$. I love the way it sounds. It sounds as if it is going to suck the hood in,lol. The look of the MOPAR CAI is also worth the $$$. I have had K&N CAI on other vehicles and it does seem like it runs a slight better, at the very least it has not hurt the MPG's. I have plans on going with an exhaust upgrade sometime in the near future. That will also enhance the sounds. So, IMO I would spend, or save up to spend the extra, but that is just my 2 cents. Hope it helps, good luck.
Hey man what do you think of the mopar air intake? Did you notice any power upgrade or sound out of it? I like that air intake better than the K&N but didn't know anyone who had one and if it was worth what seems to be about $75 more
