I have a 2002 Tahoe and I am looking at changing the exhaust. I can switch to a 6.0l exhaust since I am changing the headers to the Dynatech and have a complete bolt on. Thing is, is there a benefit to doing this? The 5.3 exhaust flows into 1 pipe before going into the muffler but the 6.0 stays dual into the muffler and out as 1. I appreciate all input....

 

You can call corsa and they will do custom assemblies. I had them do the 6.0/8.1L muffler on my s/c 5.3 so It wouldn't drone on the highway but still be able to support the power levels and flow reqs.
