Who all has experiences with the resonated test pipes sold on ebay by various sellers? How do they sound compared to a simple test pipe (pipe with no resonation at all, just a pipe)? Does it quieten it down a lil? get rid of the "angry bees" sound?
Can anybody compare an 'ebay resonated test pipe' vs. a 'race cat' from someone like Landspeed Racing?
For those who don't know what i am talking about, here's an example...
