hi, i have a honda civic si and i just put a injen cold air intake on it..what...
 

...would be the best muffler ?? im looking for fa muffler that sounds good and not louder than 95db...

Before you get to the muffler there are other restrictions in the system that should be addressed.















Such as the exhaust manifold, and catalytic.















You should be able to find a complete system for around 1 grand, most likely less if you shop wisely.















As for the sound you want, go to you-tube and do a search for Honda Civic exhaust and there will most likely be clips of different makes of exhaust systems that users have recorded to help you select the one you want.
