Just got my test pipe on the other day. It's 2.36" with no resonator. Fitment and finish was excellent. The car definately is louder although a bit raspy at least from the outside. It makes a really cool whining noise right around 3-3.5k rpm. Here is a little clip. http://media.putfile.com/s2000-reving

 

Is that a stock exhaust? If so, it would sound better with an aftermarket I think. But it's not bad as it is

 

does the test pipe replace the box-style stock resonator that some people take off to get a slightly louder exhaust note?

No it replaces the catalytic converter. The pipe your talking about is another resonator apart of the stock exhaust system (forget the real name for it---its like hans pipe or something idk)


I didn;t know invidia made a testpipe for our car. Eithor way, now get the catback matched up with it and you'll be golden

 

yeah I had no idea either but yep thats stock exhaust system, more or less a temporary thing, thinking about t1r70
