Megan Racing O2 Works Just fine, Theres really no Huge difference in any of the O2 housings. Megan will do just fine on a 16 or 20.

Buschur sells their exhaust with a magnaflow muffler, maybe that is the system you have. check to see if it has the slip fit clamps instead of flanges! if thats the case your guna roll with the buschur test pipe.

 

If you care about the sound (I do and a lot of cops too) get a resonated test pipe. You will appreciate if if you do a lot of highway driving and like to be able to hear the radio. Some time ago I did not care about the sound but now I do. I think I am getting older.
