I have the HKS ti-carbon exhaust. I have been trying to find out wether the inner diameter (ID) or the Outer diameter (OD) is 3" inches. Im trying to eliminate the resonator and need to know these dimentions.

Thanks people

 

its less than 3 inches

the muffler is also LESS than 3 inches

 

Measure it with a tape measure...

 

Less it is but you make sound as if its noticeable. the pipe diameter 75mm=2.95 inches the tip is 120mm=4.72 inches you can use 3 inch pipe just fine. But I have to ask why are you eliminating the resonator? I have the Hi-Power and the resonator doesn't add any restriction but it you are trying to make the exhaust louder eliminating the resonator will do that for you.

 

thanks guys

 

75mm/25.4mm per inch = damn near 3 inch. 2.953in to be exact.
