what about a s2000 muffler on a civic? has it been done and how does it sound? would there be any performance gains or would it be best to get a loud a$$ straight through i want a nice deep mellow sound with out the headache and attention from the law!

 

 

will fit just alittle customer pipe here and there my friend has it on his car.. sounds pretty damn good..

 

i have the stock s2k muffler on my del sol with 2.25piping, it sounds great, it's a little sound then stock, but quiet, with the window up, u barely hears it. but i dont know about performance on it (imo: it's great on low end but kinda restricted on high end)
