Exhaust Mod

I have seen a few threads regarding improving the sound of the boxster, and I am somewhat interested myself. I have had this idea for a couple months and thought I'd share it and hopefully get some feedback. I used to drag a stroked LT-1 camaro. I installed headers and instead or replacing the exhaust I installed a Y-pipe between the collector and cat. The Y-pipe had plates that had different sized holes to control how much exhaust went through the system and how much went straight out. These plated were easily interchangible with wingnuts. That made for a nice stock looking exhaust for a bit of the sleeper effect when I switched the plated out. I have been considering a couple Y-pipes on both inlets of the muffler of the boxster. This would be for sound versus performance, and with a set of interchangable plates with different sized holes, I should be able to control or tune how much exhaust is muffled and how much is raw, unrestrained sweetness. When I get pissed at my neighbor's early morning mowing, I can take both plates completely off and let him experience the raw unrestrained sweetness.

anyone have any thoughts or foresee any complications

Other than grossly poluting the environment for noise, not really.. I'm not a tree hugger or anything and my talon doens't run a cat because it's turbo, but on this car I don't bother cause if it's really not making a huge difference and the added polution is just not worth it.

How about something like this?

Since it seems like you probablly can weld and fabricate, take some 1" pipe and run it from the entry before the muffler and out the tip by-passing the muffler totally. Apparently this sounds quite nice and add's a lot of grunt to the boxster exhaust. Chances are if you run a modded car at the track you can fab it up in your garage. I have a tig welder in my garage and will probablly whip this up in an afternoon.

A very nice forum member just sold me his 2.5 muffler and when I get it, I'm gonna get a muffler shop to weld them pipes on the side for me just like the ebay guys from Germany. I need a much louder exhaust. It sounds whimpy.
