I'll start off by saying I'm not any planning illegal mods - my Grand Marquis is a Mid East spec made to run on leaded fuel. I have no catalytic converters, no oxygen sensors and no EGR from the factory. The EGR hardware is there, but it's deleted from the PCM. Found this out the hard way, when I was trying to delete the EGR system myself.
Long story short, I had 2 resonators in place of the rear catalytic converters on my factory h-pipe:
I had a thinner, driver's side tailpipe welded in place of these resonators, which was off a '10 Crown Vic at the yard. At anything past half throttle, it rattles like crazy.
The engine feels noticeably lighter at highway speeds and I'd like to maintain this setup, minus the rattle. So I'm looking for off-road mid-pipes/down-pipes that run from the exhaust manifold to the H-pipe. Just wondering if anyone know where I can get them, and if anyone has any recommendations.
I'm not looking for anything obnoxious, because the plan is to later upgrade to Stainless Works long tube headers without catalytic converters and an X-pipe next year. I just need something that doesn't rattle for the time being. Thanks!
