Factory DP + Res delete with this muffler is pretty good. I put in a CTS catted DP with the res delete and it sounded raspy asF.
If you ever plan on putting a DP might as well put in a vibrant resonator. I could've saved 100$ on the res delete even tho I didn't think I would buy a DP even tho I did LOL.
I still love the clubsport muffler. Makes the rear look so dope and if you clean the tips often it shines like crazy.
DSG has the farts when shifting, Manual does not...
