Made up my mind sell the Denco dump pipe and buy a complete Scotts rods 3'' system,pillar pod and gauges on the way from Extreme Limits Offroad then off for a dyno tune,anyone after a 3''_ 2 1/2'' dump pipeIt's annoying isn't it. I specifically asked Denco if their dump opened out to the full three inches and they told me i (on the phone) that it did.
It doesn't. The clear opening size is 66mm.
I installed it anyway as it's the only one I know of that bolts up straight to the factory exhaust.
On the positive side. It bolted up easy and improved both boost response and economy.
When I was looking there was this one as well. Doesn't appear to still be available though...
