4 inch exhaust

Good Labor day morning.
I have been reading about the 4in. exhaust and thinking of what Motorhaven sells.I had also read about hammering the firewall to fit the 4in. downpipe.Any truth to this? Anyone running this system? +/-'s of it.
New to this,so I need alot of help.
Thanks Gearloose

Thanks,does the duals exit to one side like the stock pipes or out each side?
I would think there would be no room for them to both exit on the right.

Hi, got the ATS 4" full system (single)... easy install, no clearance problems, very nice, I would recommend it. Really helped my EGTs stay low.

I have not heard a Diesel with Duals. What does it sound like?

I've heard one, and it sounds like stereo. This happened to be a highly modified truck, but it was among other highly modified trucks, and sounded like a cross between a strong diesel, and a strong gasser, because of the duals. Very nice!!
I built my own 4" system using a piece of 4" aluminized pipe, a huge Donaldson muffler, and the mandrel bent tailpipe from a SuperDuty. Mine attaches to my Hypermax downpipe, and breathes very well. All together, mine only cost about $325, including the downpipe.
