You've done so much work with the exhaust to lose that hard-earned HP. A good weekend spent learning the ways of Dynamat would keep the interior solemn while letting those rampant ponies enjoy the outdoors.

I know I know... Just do not have anymore time or money for that. We will see how much I lose when I re dyno with the new OEM style muffler.
They say it is close to a 40% loss on the all wheel dyno. But they are not even sure. Thinking I am about 300 or so.

Finally got the VX sounding how I want it... Removed the Magnaflow muffler and replaced it with a DynoMax Chambered turbo muffler. Replaced the 3” tips with 4" tips with 2.25 resonators in the tips. Also added a custom Stainless Y-pipe. Sounds great just what the doctor order... VERY pleased with the whole setup (2.5 Stainless Steel pipes all mandrel bent and tig welded into Magnaflow cats into a Single 3” in Dual out DynoMax Turbo muffler with dual 4" resonated tips) and it feels just as FAST as before Has a really low grumble now.... will get it re dyno'd again soon and post new pics of the tips.
