Gold, have a look at this page:
Full Alfaholics Stainless Steel Sports Exhaust System for 3.0 V6 GTV
This shows the 4 sections of a 3.0 V6 exhaust.
1. 2 front pipes
2. Cat (Catalytic converter)
3. Centre box with one silencer (muffler)
4. Rear section with 2 silencers
Although this is all in stainless steel, it's a copy of the original AR system, with the same amount of silencers in the same positions.
Technically, mine is exactly as shown apart from the rear section, where I now have the Ragazzon straight-through pipe with no silencers. So as far as I'm concerned I am just running one silencer (centre pipe one) and I lost two silencers by replacing the AR back box to the straight-through Ragazzon one. I still have the original Cat in place.
Going from Big Dogs set-up, he has no silencers but has kept the cat. For me that's too loud for every day use. Though it sounds great, it would be too much for me all the time and I can imagine the cops pulling me over if they heard me accelerating...
Is your system exactly the same as pictured in the Alfaholics page apart from a straight-through Ragazzon centre section?
