Yes, your muffler will fit your car,
There are a couple options you have though!
1) Put the muffler on... You will notice a little increase in volume of sound and a LIL deeper tone.
2) Put the muffler on... Have them straight Pipe your Resinator, You will notice more Volume than (1)
A Resonator is a second muffler that is under your car, just another little hump in the exhaust pipe.
3)Have them put on the muffler w/ 2 1/4" pipe back to the Cat, No resonator of course, You'll have the Deepest sound you can get out of your 4-Banger, and it will be Loud, ... A nice stereo w/o subs will drown it out for you, Others on the road will hear you coming though
Having number (3) is going run you around $200... number one $60 ... that what it goes for in my area..
Also is your Muffler a Straight thru design, A 2 chamber , or 4 chamber, .... If it is a 4 chamber, return it , it will sound like a Moped, if it's a 2 chamber .. well it's your call I think a Honda will sound a little Nasal. You'll get the best sound from a Straight Thru.
