can anyone tell me what's the stock inlet pipe size for a 99 Integra GSR? I mean the one goes into the muffler.

I am trying to put an after maarket exhaust and would like to get an aftermarket muffler with the same inlet size so that it can welded on easily.


Thanks

 

if i recall correctly its flared to 2.25" to accomodate the donut gasket on the b-pipe. the actual piping is 2.0" though. i'm not 100% sure, but fairly certain.

 

Anyone knows for sure??

If its 2.0 ", would this mean that I need to buy a muffler with an inlet size of 2.0 " or 2.25"? or a muffler shop would be able to weld a 2.50" inlet muffler to the existing inlet pipe?

 

It should be around 2.09"...that is the exact diameter of the GSR exhaust piping. PEACE!
