Exhaust tip inlet diameter?

OKay i looked through thr threads and am still confused?

What i want to do is cut off the end portion of my exhaust and put a new tip on.

I measured for sizes by doing:
Pi X Diameter = Circumference
or,
Diameter = circumference/Pi

For the very end, the "flared" out part we got a pretty good circumference of 8.5in, so that would make the diameter 2.7 inches.

For the regular pipe size the circumference we got was 7.5in, making the diameter ~ 2.4.

So i want to know what inlet size on the new tip i should be getting? And what are the exact values?

thx

 

Why are you doing all this math!?? Measure one side to the other? No one makes a 2.4" exhaust. Most likey 2.5", so that would be your inlet.

 

aaahaha. i know they dont make 2.4 or 2.7 sizes, but i just didnt know which was right?

 

SO did this 2.25" one slip on?

 

on summit racings site there 2.410" inlet diameters

 

any more input on which size to get for clamp on tip?

 

chop off the flared end, get a tip with a 2.25" inlet. Call it a day.

 

okay thanks!

 

So this is stock exhaust? If so, then yes 2.25...

 

ok so I got a 12" gibson 2.25 inlet clamp on exhaust tip and the damn thing won't fit on!! I cut off the flare and even filed the end of the stock exhaust a bit, but it will not go on. While trying to put it on I also opened the clamp end a bit more with a chisel, yet it still wont go on! What should I do?
