have an 05 stage one Roush with stock headers, K&N intake, pypes x-pipe deleted cats and FRPP's. I took the FRPP's off yesterday to see what it would sound like. It's LOUD! and I like it. I'm concerned that running basically straight pipes will cause harm to the engine with there being no back pressure at all. Have heard off valves burning, running rich, fouling out plugs. Before I take her over to the local muffler shop to weld straight to the back wanted some advice from people here about this setup. My other thought is to run Flowmaster super 10's??
here's what it sounds like. There's some reverb from the garage, will get better vid today.
