muffler bypass - pointless!
From : nathan in montana
Q: cut out my muffler and welded in a piece of pipe and the difference is next to nothing. it really doesnt sound any louder than before i removed the muffler. the only time i can tell any difference at all is during heavy acceleration. ......anybody ever gut the cat instead of removing it completely -- nathan in montana http//concealedcarryforum.com http//1911talk.com http//glockcarry.com .

hey before you gut it check out the prices at your local recycler/ smelting operation....for years id just punch the grid out on a melted or non-smog vehicle and these days the prices are amazing! the lowest price paid at the local yard small universal pre-obdii was $35 i got $70 for the one i was turning in. might be smarter to splice in a section of pipe. jon .
