Comments about Walker Quiet-Flow SS Muffler Assembly:

Used on my 94 Toyota Pickup, 2wd, short bed. Fit well except under the wheel well...a little tight that required a small tweak bend to fit right. Had to replace my whole system due to age and rust. States you need to have the new/longer hangers but my old ones worked fine. Returned the hangers to the local store for full refund.
