New thicc exhaust (video included)
Everything other than mid silencer is new, this straight-through muffler is made by a Polish company RM-Motors. Sounds just great. The exhaust is 60mm (2.3") from the manifold to the mid silencer and then it is 50mm (2") to the rear one, the outlet of the muffler is 76mm (3"). Oh yeah and the engine in my Jetta is 1.6L EZ (not that it is easy or anything, it is just its code lol). I have no idea what that whine from the engine is, probably it is just cold and some pulleys whine.
