Perfect Beautiful welds
Had the zzp 3" full straight pipe system. Bought the muffler section to quiet the car down. Couldn't be happier how easy it is to swap this in place of the muffler delete pipe. Sounds perfect.
Hhr SS rear muffler
I had the zzp 3" already so this was a 10minute install. Sounds decent enough for the lnf motor. For those wondering what "chambered"design is. It's a resonated muffler on each end with a hollow chamber connecting the two resonated ends. Tip looks way better with the rolled /slanted tip cut flush but that's preference
Sounds great quited the car down alot and has a nice rumble to her
Cobalt chambered 3" muffler
I purchased the Cobalt chambered 3" muffler. In the beginning I had a rattling 2 1/2" muffler, got sick of that noise quick, cut muffler off, better sounding a bit loud for my ears. Purchased the 3" muffler and yeah boy!!! The Cobalt sport 2.4l sounds like a sports car! Deep throated but not too loud just Goldie Locks! Perfect.
