FLOWMASTERS HERE



Depends on whether you want performance or sound.No Flowmaster will flow as good as the Walker products.There are charts everywhere with flow number comparison on just about all brands.The Dynomax products are at the top of the list.It also depends on whether you want a muffler that looks like a muffler or one that looks like a can with the ends welded on.
