Muffler for my 2003 5.3 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a new flow master delta flow 40 that was bought for my 93 silverado 5.7 but I don't have that truck anymore, Does anybody know if I can use this muffler for my 2003 5.3?

I don't think the muffler cares what truck it goes on? I would use it if thats the sound your going for.

The delta flow 40 will sound good on a 5.3l. The only problem you may have is with the size pipe on your truck fitting the inlet on the muffler. You can get different size pipe adapters at most auto supply stores.

The 5.3 stock muffler is dual inlet, single outlet. Depending on which muffler you got the one for your 93 could be signle in single out or single in dual out.
