Offshoreonly.com - Exhaust parts

I have some spare parts I don't need: I have a pair of 4" risers I have been told they are the stainless steel ones, I have seen them on ebay for $390 plus ride I'm asking $300 plus ride, also have a pair of angle cut exhaust tips they need cleaned up make me an offer with ride, also have a pair of Corsa Y Pipes with valves 4 wire don't know if they work asking $200 plus ride. I have never used any of these parts, I had got them when I was buying other exhaust parts. The risers won't work with my TRS drives cause they don't have fittings for water for the trans cooler (thats what I was told) I have twins I had 1 set of the cast and 1 set of the Stainless Steel, I got me another set of the cast. And I found me a twin set-up of merc silent choice so I don't need the single Corsa pair. I can only up load 5 pics I have more if you need other pics pm me Thanks for looking
