    Options to quiet down 3" turbo back exhaust on stage 3 1.8t?

    I'm almost 30 and my stage 3's turbo back straight pipe exhaust is just to loud. Was thinking about a vibrant 3" straight through, single glasspack, offset flow master, anything to make it mean and tame.

    Options?

    Anyone use a dual chamber or should I stick to flow through?

    I had dual Magnaflows and I ducking hated it. So much drone
    I switched the rear one to a Dynomax VT, and loved it for a while. It rattles sometimes, much more so when cold, especially on start up, but not bad when it's hot. But zero drone, mild idle, loud wot. I'm tempted to switch my mufflers around, but I'm too lazy.

    We would recommend adding a small center resonator and rear muffler to quiet it down a bit. Chambered mufflers aren't the best for forced induction applications because they retain a lot of heat and still have some restriction. A straight-through style muffler like the ones we offer will flow just like a straight pipe, so you don't lose any power or spool-up time.

    We'd be happy to assist you with choosing components for your exhaust. Please feel free to PM us if you have any questions!

    I run the 2.5" version to a Magnaflow.
