[bringeroftruth]

Does any one know the exact measurement of the exhaust piping on the v6 3400 alero, im cutting out my cat and putting a high-flow one on but the cats size is just alittle to big and i need to know the exact measurement so i can get the right reducers. i want to go with 2.00'' but im not for sure, im also cutting out my resinator and putting in a piece of straight up which is another reason i need to know the measurement thanx and i hope some one can help.

why dont you just get a tape measure out...

[bringeroftruth]

in order to do that id have to cut the pipe, and thats what im trying not to do until i get the right measurement, i dont have two cars only the alero so if i cut the pipe open then find out the measurement id have to drive down to advanced with out a muffler. were trying not to do that.

2" OD tubing on every Alero regardless of engine

if you measure the circumference you can find out the diameter...

C = pi * d

so say the circumference is 6.3 inches..

6.3 = 3.14 * d

d = ~ 2 inches
