3.73-11

I've run an h pipe assembly on a 2010 4.0 a mac pro-chamber on a 2006 4.0 and now a pypes x pipe on my latest 2010 4.0. All have had their merits to be honest I like the current setup a lot as it is deep and sounds good with some burbling popping on deaccel which I love. And drone is minimal ie you can have a conversation unless your lugging along in 5'th at under 2000 with a load or steady state cruising. The others we're a little deeper tonal wise but def droned more also as for performance gains who knows mileage seems to improve around 1 mpg or so when you switch to duals. Vids of the h&mac systems

i watched every video and my choice is H pipe which sounds like a real muscle car. This is my opinion of course. Nice post man.i wish i could see same post for V8 someday.
