i was wondering if the 1992-1995 Civic Si muffler has larger inlet and outlet then other 1992-1995 civic hatch mufflers. i was looking on hondaautomotiveparts.com looking to order a muffler, and i notice a 1995 VX had a different muffler part number then the SI model. also, if i order one, will it be brand new? or used? my muffler is going out and i dont want another used one on. if they are new, is it all one size fits all or one for each Civic model?

 

where are you ordering from that you think you might be getting a used one?

 

dealers only have new parts correct? i wouldnt see why they would keep used mufflers.

 

my point exactly.

 

so does the Si have a better flowing muffler? or would it matter? i notice the Si has a bigger outlet but i would like the know the inlet size. only want the best flowing for my baby.

 

Call the dealership, and ask.

 

I can tell you that the '96-'00 EX coupe muffler is a different part number than the '99-'00 muffler, but the two seem to be identical (replaced my stock muffler with an Si one when mine rusted along the front).

 

i just dont want to buy a new muffler and it has a little pea shooter outlet, i want something like this:

when i place the order, do i order one for a Si hatch becuz of a bigger outlet?
