i need to know what the stock exhuast pipe diameters are on a 1990 supercoupe. where it goes into one pipe, is that a 3 inch diameter? what about right after the cats, what is the diameter on those pipes? the pipes that go into the stock resognator, are those dual 2.5 inch in and then one 3 inch out?
i was thinkin those were the sizes, but when looking on supercoupeperformance.com at the high flow cats it said something like 2 1/4 inch diameter.
i would just like to know what the correct sizes are. my plan is to put in a magnaflow resognator, high flow cats, and to delete my mufflers (i read this gives a very nice sound). but i would just like to know what the exhuast pipe diameters are so i can be sure to get the right size pipes. thanks.
