70chevy03ss Posted May 27, 2009 Report Share Posted May 27, 2009 Ok I have an 03 Silverado SS. My current setup (how I bought the truck 5yrs ago) is a dual in/out flowmaster muffler behind the rear tires that flow threw huge 4" tips. I love the sound and love how when I drop it to 3rd it rumbles and pops. Well thanks to good old New England weather it's rotting. So I need help. I like flowmaster but I have been reading alot of people don't and that it hurts performance. I have been reading about Magnaflow and I am leaning towards them. But what part number do I go with 11379 or 12599? Or something else? I want a Sweet sounding here i come exhaust. But i don't need to be walking up the dead as this is my DD. I have a "BLOWN" 70 chevelle for that. I will be putting OBX LT's on soon but not to soon. Also I will be sound proofing the truck in a few weeks as well. I am not looking to spend a butt load of money as well!!! SO please please help me out. Thanks Quote Link to comment Share on other sites More sharing options...
JF-03-SS Posted May 27, 2009 Report Share Posted May 27, 2009 So I need help. I like flowmaster but I have been reading alot of people don't and that it hurts performance. I don't know where everyone comes up with that. I ran a di/do Flowmaster50 and I can't say the Corsa I am now running flows any better. So IMO if you want another flowmaster, go 4 it!

Jond983 Posted May 28, 2009 Report Share Posted May 28, 2009 if u can spend the dough..get corsa w/gutted cats Quote Link to comment Share on other sites More sharing options...
zachm89 Posted May 29, 2009 Report Share Posted May 29, 2009 I'm running 2 Flowmaster 10 series single chambers on my SSS and its really not THAT loud and not alot of drone either. Im also planning on adding a set of OBX lt's and since the cats are hollow im sure its going to wake up my exhaust note a little bit. With the stock manifolds and cats the single chambers arent bad but i have a feeling after i get my headers i will be going to a different muffler setup.
