Do these flow better than stock or are they the same as stock.?
Walker Mufflers from Summit Racing

 

Walker has always been just a stock replacement part.

but...

Walker is also the maker of Dynomax, which is a performance muffler.

I run one on my truck, and although it's no Honda, it does run better with this one, as opposed to the stock one and the 3 other performance mufflers/exhausts I have tried over the years.

 

Walker is good, you get what you pay for in my opinion..
Want HP gain of some sort, then look up performance exhaust parts..
