Hi all,

I recently acquired a 2000 Si and I'm looking to make it as stealthy-quiet as possible. Current setup: Test pipe, resonator, OBX-R twin loop muffler.

Any suggestions for a VERY quiet performance muffler? I drive mainly on highways, so it should be quiet around 4-5k RPM. Also, I've read that Dynomax Super Turbo and Borla Pro XS are pretty quiet (I thought the Borla was still pretty loud tho).


Thanks.

I used to run a Dynomax and it was pretty quite (not sure of the model I had though).

Have you check out Vibrant?

Go back to a stock setup.

I also recommend the Vibrant. I know some guys who have this muffler , and it is really quiet.

I'd look into the A'PEXi world sport 2. Not too loud, nice low sound. Doesn't get really loud unless you get on the throttle.

That's probably the best video I've seen for the exhaust sound. He actually holds the RPMs for a bit instead of blipping the crap out of it.
