engine tune with stock downpipes

Groundpilot · 01-13-2011, 11:08 AM

Hey everyone. I have a question about tuning the engine. I am a complete noob when it comes to any kind of engine tuning, but after reading so many great reviews about jb3, procede, dinan ect, i decided to pick one of them. But here is my question. I was told by my mechanic that if i run my engine with increased boost and stock downpipes for prolonged period of time(track lapping for example), the engine will be under additional extra stress that will negatively affect longevity of it. So aftermarket less restrictive catless downpipes should also be installed to adress that issue. Is this true? Also, will the car pass annual inspection in new york with catless downpipes? Any input will be greatly appreciated.

We have OBD emmissions test and no sniffer so all you need is a CEL fix. Not sure if it's N55 compatible but burger motorsports sells them (same company that makes the JB3)
