03SSrado Posted February 14, 2010 Report Share Posted February 14, 2010 Hey I've got an '03 ss silverado with stock exhaust. Looking for a little more rumble w/o doing whole exhaust. If anyone has an aftermarket performance dual in and out muffler for my truck for a mark down price please contact me. Thanks, Jacob Quote Link to comment Share on other sites More sharing options...
03_SS_22 Posted February 14, 2010 Report Share Posted February 14, 2010 so are you going to dump it? stock muff is a dual 2.5" in/single 3" out. Quote Link to comment Share on other sites More sharing options...
alex.t Posted February 14, 2010 Report Share Posted February 14, 2010 (edited) no i think the stock is dual in dual out with a y after the muffler. in mufflers you could get a 18" or 22" magnaflow muffler for like 100-120 bucks on ebay.

zachm89 Posted February 14, 2010 Report Share Posted February 14, 2010 yup...stock muffler is di/do with a y-pipe after the muffler to the single tailpipe. Quote Link to comment Share on other sites More sharing options...
03SSrado Posted February 15, 2010 Author Report Share Posted February 15, 2010 Yeah its di/do im guess 2.5'' both ways into a 5'' pipe?? im estimating that. Yeah i found a magnaflow, i appriciate the advice, just wonderin if anyone on here was maybe switchin up exhaust systems or had one for cheap. thanks guys Quote Link to comment Share on other sites More sharing options...
zachm89 Posted February 15, 2010 Report Share Posted February 15, 2010 believe its only 3.5-4", not 5". 5" would be ridiculous! haha Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted February 15, 2010 Report Share Posted February 15, 2010 Its dual 2.5" in and out to a 3.5" Y pipe. I have my old 18" Magnaflow 2.5" dual in and out muffler that I just took off but for the price it would cost to ship I would rather sell it locally..

03SSrado Posted February 15, 2010 Author Report Share Posted February 15, 2010 believe its only 3.5-4", not 5". 5" would be ridiculous! haha Yeah after typing that and later going out to look at it i realized my first guess was way off. At a glance it looked big, but youre right, definitely not 5'' Thanks guys Quote Link to comment Share on other sites More sharing options...
