a6t8vw Posted November 22, 2006 Share Posted November 22, 2006 sup fellas, i was thinking about running a sinle inlet 3" dual 2.5" outlets flowmaster backwards is it safe? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted November 22, 2006 Share Posted November 22, 2006 Don't know too much about them other than that they're a fairly restrictive muffler. If you look at a cutaway of them though, it looks pretty clear that the exhaust is intended to flow in one direction and not the other.

240zV8 Posted November 22, 2006 Share Posted November 22, 2006 It doubt it would hurt anything, but it defeats the purpose of a muffler. It would probably sound wierd, and there built to flow one way, so it wouldn't be a good choice to me. I take it you have a 2.5" exhaust that you don't want to change, and you got that muffler cheap? You could find a shop to just make a adapter for 2.5" to 3" so you can run it the right way. Quote Link to comment Share on other sites More sharing options...
a6t8vw Posted November 22, 2006 Author Share Posted November 22, 2006 Well i was intending as using it as a Y-pipe. im running a v8 and was thinking headers into the dual 2.5" inlets of the muffler then Single 3" all the way back to a magnaflow, I was concerned about too much back pressure?

Warren Posted November 22, 2006 Share Posted November 22, 2006 Or if you don't want to rely on ebay, you can go to http://www.justmagnaflow.com and they'll ship it immediately. Both Gabe and Myself received ours the next day, before they had even charged our cards. Quote Link to comment Share on other sites More sharing options...
