Thanks Stroked & Blown.

As I get used to it, I like it more and more. Here's a pic all cleaned up.

Woah! an 8 wheeled Boxster!
That mush corner like a dream.

S&B, that's funny! :dance:

Here's something I've been thinking about. What if the two mufflers were connected with sheet metal making a continuous cylinder? Could the space in between the mufflers (8 inches or so) be used as sort of a balance chamber? Would there be any advantage in performance or sound level? I’m using layout “A”. The exhaust streams could be mixed in the center chamber either by deleting the internal tubes entirely or perforating them. Maybe someone from Flowmaster is following along could give us an opinion on this.

Wret was nice enough to let me come check out his muffler set up today. It is a VERY nice sysytem. Really clean with quality workmanship and it sounds great, closer to a 987 but alittle louder. We didn't have time to take a ride in it but when he revved the engine it had a nice growl. Overall, a quality muffler that is as good if not better than most aftermarket systems on the market today.

Any time JTP. Let me know if you want to take it for a spin. By the way, here's a parts list if anyone wants to put one of these together.

Hushpower DBX mufflers 2” inlet/outlet (2). Special Order by phone from Flowmaster. At the time I ordered, 2” ID was the smallest diameter available. This requires shims to get down to the 1 ¾ inlet pipe. Call 877-394-2878 ext 716 for more info.

3” Stainless tips, 2” inlet. Max 6” length. A 6” tip will protrude about an inch more than the stock tips, which to me was not an issue. If you want to keep the tips tucked as far under as stock, you will need to find a shorter tip. I bought these from Summit but you may be able to get them direct from Flowmaster.

2” 90° bends with 2” radius (2) Don’t get a larger radius or they won’t fit.

2” 90° bend with longer legs. The bends above have very short legs with very little excess material. Some 2” straight pipe is necessary for shim stock (only really need about 6”). This one comes from Jegs and may get you a free hat. 

2.25” muffler clamps (2) preferably stainless steel
http://www.summitracing.com/parts/SUM-694722/

Replacement bolts and nuts for clamps between the cats and mufflers (2) preferably stainless steel. M8 x 50mm (or longer). The bolts will likely be unusable after removal and may need to be cut.

M8 x 30mm (or longer) stainless bolts for hangers (2).

I don't believe you'll see any performance gain by connecting the two mufflers, though you should be able to change the sound a bit. Without baffles or packing you probably won't lessen the sound though.

Wret,

how does the weight compare to the stock unit?

Reviving an old thread. To the OP, do you have any pics of the setup?
