what flowmaster muffler should i get for 2014 challenger

 

None. Go to blastin bobs.

 

How deep is your wallet? And are you after sound or performance? Flow Master has several models to choose from that do both.
But, there are also several different brands to choose from that can and will do the same too.
In the end, it all depends on how much money $$ you can afford to spend to get exactly what you want.

 

Have you looked at the Borla Cat Back Exhaust? It might be worth looking into for your car.
