I bought a jdm n1 muffler how well do they work?

i bought a jdm n1 style muffler off of ebay. i haven't yet put it on but i would like to know. do they last


and also are they loud and deep toned?|||yes they are loud, the tone of a exhuast comes from the width of your pipes, the density that your catylatic converter allows threw and the fuel to gas ratio. So without knowing if your running rich or lean and what specs your pipes and catalytic converter are, We can not tell you if the exhaust will have a deep tone. How many times are you going to ask the same question???|||Just about all after-market mufflers are loud and deep toned. Probably would've been good to have asked the seller this before you bought it, but like I said, chances are good you'll be happy with the loudness.
