As I look at the beautiful, but restrictive CR 1 side pipes in my garage to be installed and think "I need to cut these apart & then refinish them" to get real performance, I really pause. Then I think about the first time my wife gets a "snake bite" getting in and out and the screams of agony (from me- not her, as she yells!).

My question is, has anyone here installed an underbody exhaust system on a CR? I have seen a couple of examples of FFR cars converted. They used the oval style mufflers to keep a lower profile.

I would have to install heat shields under the body at the muffler locations. But getting around (or under) the rear end could be tricky with the gas tank. My first ride in an original 427 when I was 17 was a non-SC version. But I still remember the exhaust was pretty raspy even with the rear exiting exhaust. And that was compared to my 55 Chevy with a 2 1/2" exhaust exiting under the car in front of the rear axle (huge drone at certain speeds).

I also would have to use different exhaust headers on the 5.0.

Suggestions?
