i just found this on ebay http://cgi.ebay.com/ebaymotors/ws/eB...&category=6771
it looks pretty cool, how well do you think it will work? and what do you think it will sound like? should i get this or a flowmaster muffler? i figured if it went for under 30 bucks or so it would be good. what do you think?

 

I have something similar to that on my car. My otherwise stock LO3 has a fairly deep rumble at idle, (not loud) and a noticeable but very tolerable interior resonance at highway speeds. Stand on it, and it's pretty hard to miss.
Would I do this? Not sure. My car was like this when I bought it. I don't really dislike it, but it's not a performance upgrade, IMHO. It just gives your exhaust a more aggressive tone. And mine flows about 90% through the left tailpipe, given that it has the straight through routing.
Actually I intend to replace mine with a 3" catback, probably Hooker. Now, it's your car and your money, do what you will.

 

Something like that looks like it would be super easy to make yourself. Also if you made it yourself it would be a whole lot cheaper. Just a thought.
