Re: 427 FE engine, under car 'street' exhaust system?

Its generally not necessary to bend the oval sections around the chassis. They only need to be used under the frame - maybe with horizontal bends in a flat plane - where ground clearance is an issue. Oval to round adapters can be used to transition to header connections and tailpipe sections that need to bend over the rear suspension.

With a car like mine, it's not possible to run 3" downpipes adjacent to the footwells. I just feel there's just not enough space for a practical and serviceable installation. With a 2 x 3 oval downpipe there might be, but no point if you can't get it to transition to under car, where it would have to twist.

I think it's 2.5" or revert (sadly) to some side action.....or run the headers forwards, then loop under the car, so no downpipes in footwells, Only downside I can see, is increased engine bay heat and odd looks. TVR did this with the Griffith and Chimaera, if they are known in the US.
