okay...I searched, but couldn't find my answer....does anyone have any true experience with the test pipes w/resonators found on ebay? ....I am thinking of installing some test pipes and aftermarket Y pipe, but certainly don't want any raspy noises of course. I have read to get the test pipes with resonators to help reduce the chance of unwanted noise, but I don't know if the ones on ebay are any good...they are listing for like $120-130 with no indication of manufacturer....just T-10 whatever stainless, blah, blah, blah.... any help is appreciated..

I think you're referring to the Megan racing test pipes. There are a lot of posts about these on my350z.com if you do a search. Also, search on here for Megan and you will get some more results.

 

I bought a pair from ebay, just put them on....dont do it lol. Sounds like damn civic exhaust.....hoping with the hks hi power it will sound a little better. Its weird casue everytime i left off the exhaust it sounds like something is rattling around down there im still not sure what it is.
