That sounds great, I you don't mind me asking, that is the exhaust currently selling for the Sierra correct?
Not sure, all it is is the muffler only. Its the round one note the squared looking one like the cat back system (not sure why there are 2 different ones). I originally was going to get the squared one but after they showed me how it sounded and tried the Borla XR1 I liked the S type. From what I've read the XR1 is a lil louder and when I heard it sounded more throaty.

In the process of buying a RST 5.3 and looking to see what muffler to install. Called a local shop and recommended NOT to get the FlowMaster Super 10 b/c of the size of the muffler and will cause back pressure? Recommended a muffler delete or a Carven muffler? Anyone have any experience with this brand? Never heard of it.

Yes sir! I’ve had carven on my previous hemis and even on the 3.6 jeep engine. Carven is loud. Sounds good. I’ve heard and watched the YouTube vids on carven for the 5.3 and honestly the vids don’t do it justice. So after they cut my stock muffler off they tried the borlas and even had a Carven R series that they tried and it was louder than the 2 borlas they tried. Sounded good but for me personally I didn’t want too loud. If you want loud it sounds good and I would recommend it. As for the muffler delete it’s loud but too raspy.
