My '68 isn’t a G car, but I am cutting out the rear valance and adding the chrome bezels for the openings. I have 2-1/2" pipes; what are your opinions on sound change, and horsepower change if the exhaust is restricted down to 2" with the tips that a few places are selling as G and Shelby GT replacements? Will it be an insignificant change? Has anyone bought these? Do they look good?
SO your talking about just reducing the size at the end (tip)? IDK, I like the looks of the G exhaust, but I imagine it’s far enough back it won’t make any huge difference. Most of the restriction is going to be closer to the heads…it may tune things differently you could test it quick by putting on some reducers as is quick and see if you like the sound…then you haven’t chopped or cut anything at least
