Reply to "GTS vs Non Exhaust differences"

bosswrenchMember

Both std & GTS are made by ANSA of Italy, but the std exhaust has a 1.75" OD inlet tube and a 'final baffle' on the outlet of each chrome pipe, while the GTS muffler has a 2.25" OD inlet pipe and no final baffle. This of course matches the much higher exhaust flow from the semi-equal-length GTS headers. And even the GTS muffler is restrictive when you're dealing with a street-modified 351C, not even a racer. See the tech article in the Dec 2003 POCA news on gutting and modifying the internal baffles in GTS mufflers to allow an extra 500 rpms in the upper gears, without making excessive noise.
