i see in Jegs that they carry Thrush mufflers. i'm looking for a pair of 3in/out mufflers for my 2500HD to swap in place of the OEM muffler.
the one i'm looking at is PN 289-17657. anyone know if these are worth it at the $30 price tag? my other consideration is the Magnaflow 642-12259. they are $87 each. |

Those thrush mufflers are the "turbo muffler" style (I used them on my 1977 3/4 ton Chevy). It has two or three louvered passages in them and they flow "ok", but not particularly great. If you are desperate for a muffler, they work (but can be loud). If you're looking for effeciency gains, buy a Dynomax (who makes Thrush) Ultraflow or a Magnaflow "straight through" design. Your other choice is out of stock. Hooker Max Flow also flow well.
What's the goal of this swap Glenn? |
