I put the Z tube on my car last week and I really like the improvement in sound from it. I'm thinking about picking up a popcharger after work today but I was wondering what kind of sound change it will produce? How much louder etc.

Any thoughts you'd care to share are appreciated.

 

It is loud, and has this strange whistle at about 3k if you hold it there and listen close. Very cool.

 

not only louder, but also gives it a different tone. sounds very muscular, and the whistle is nice, you can hold it at will. sometimes friends think they heard a bov

 

Well I picked one up after work from grubbs performance and put it on last night...

At WOT this thing screams! It sounds like a race car or something, I don't know what it sounds like but I think losely translated it is saying "get the _____ out of my way!"

I do hear the whistle with the windows down and stereo off. But with the windows up and stereo on, I don't hear it at all. I'll have a better idea of when I can hear it after I've had it a while. I did hear the whistle a little bit with just the Z tube, but it was very faint then. Now I can hear it much better. Under 4k rpms (normal driving) it's pretty much indetectable, but once you get on it...

I also should mention that the instructions that came with it were absolute crap. I'm fairly mechanically adept, so it wasn't a big deal, but I thought they could have been a lot better. And man, that weather stripping was a major PITA to put on, at least for me. That was the most time consuming part by far.
