    Does anyone have any personal experiance on a 92-99 Suburban with a dual in/out Flowmaster or the like? I am really thinking about getting one put on mine. TIA

    Well, I went on youtube a found a couple clips with 5.7 V8s using a Magnaflow #12568 muffler (Dual 2.5 in/Dual 2.5 out). I went ahead and ordered it from ebay for $97.97 shipped to my door! I am going to put it on as soon as it comes in using a similar factory look of two stock looking tailpipes exiting the rear side (both on one side like the older Chevy trucks). I am hoping this won't be too loud but give it a deeper sound and peformance boost.:)

    my 99 suburban came with one from the factory so when I went to put on exhaust i went with magnaflow dual/out and split behind each rear tire, love the sound, a little drine on the highway but nothing that will give you a headache and after a few months i didnt even notice it anymore, oh and I didnt notice anything off the line but it seems to gain rpms quicker for passing on the highway
