Even if there was a economical conversion from the existing twin pipe ('90-'95) as a "bolt-on" go-faster kit could be cool too. I always felt that the pipes on one side looked unbalanced and besides, even buicks today have dual sided exhausts on them.

c'mon really
Guess I'm getting old....
There is a single tailpipe option too....or, was...
Still advertised at porscheshop uk, and a few other places. And on the SS website (.it) IIRC.

^^^^^^^^ Yep............The first picture is the one I was talking about. It splits into a left and right sided exhaust pipe. It would be a little cooler with twin pipe tips on both sides but singles would work. Just a little more "updating" bling, I suppose.

rear fascia
fascia photo w/duals below. Looks like a custom formed bumper cover, or at least the lower portion.
There was a similar styling issue the '04 GTOs. Later 05/06 had true duals with left/right exits under the bumper, but the 04 had dual pipes paired up and exiting driver's side. An aftermarket co. made a trim mold for a piece that could be fitted to an '04 to match the openings in the rear fascia necessary to accommodate l/r tips, it provided a slight beveled edge and some transition underneath. Don't recall the name of the company. Edit- found distributor pfyc.com

Not what I would advocate for a "nice" 928, just rambling...
Also, to wind up the battery box discussion- photos with a dual in/dual out stainless Gibson, fairly short case, and then an internal x magnaflow- medium/long case. I went from the Gibson to Magnaflow for improved sound.

The Supersprint exhaust pipe size is 57mm(2.244"), isn't it stock GTS size? I would go for 2,5" as it will give at least same TQ/HP numbers + leaves some more area for future..

Dyno results taken with catalytic converter version of X-pipe + SS centre and rear exhaust system. Not so pad with catalytic converters, I think.
http://www.supersprint.com/en/IT/pro...e_928_gts.aspx
Supersprint:
- Metallic catalytic converter Right – Left 242902
- Centre exhaust Right – Left 242903
- Rear exhaust Right+ Left 243005
Actual data:
Horsepower 378,4 Hp at 6135 rev/min
Torque 512,9 Nm at 4310 rev/min
I still like the finishing of the products, but not the price
