Heyyy just did a muffler delete on my 09 SS and it sounds great! i def recommend it! i still have stock downpipe so im sure itll get louder but A must do!!! ( if your in the Tampa fl area and looking to have it done PM, my buddy is a fabricator and makes all my parts custom fit.

 

I would probably do it in the meantime of getting a cat back..but I hate chopping up stock parts.

 

I recently did a muffler delete too, but I think I'm going to put it back on with a new dp. I'd rather get a performance gain with a noise then just the delete that adds noise. I use my car as dd and I'd get annoyed if my exhaust get too loud again like my last car.(ss/sc)
