Add the HFC's and drive around with them and see if you like em. Take a video.

If you decide you don't like, then consider adding another set of resonators ($100)

I think adding the s-line mid pipe would be perfect. It too will give you hp gains and it should give you a deeper growl without a significant increase in sound. But I get it if you are on a budget!

thanks for the idea, Ill look into it. even still, i know i wont be happy until i squeeze power from every piece of the exhaust system... :ughdance:

Yeah big worm- Their midpipe gives 19whp/19tq without a tune.
Short tails obviously do nothing. But that at least gives you some more power. Only problem is $$$. They want $800 or join the group buy that might be ending or over..

Anyways, you can almost get a new exhaust for that price, so thats something to consider!

buddy of mine took this video yesterday as we were coming home from a meet.. I down shifted from 5th to 4th and got on it a little barely going over 4k rpm... its actually funny how loud it gets after 3k rpm..

video was taken with a phone so not amazing quality.

370z exhaust loud!!! - YouTube

VERY LOUD! ^^^

HFCS add a ton of sound to that Top Speed. Wow.

That's pretty loud and now makes me want someone to film mine. I could only imagine the volume lol may break the recording device lol

DO IT DO IT! :happydance:

Nothing is funnier then rolling up to someone in a tunnel with there windows down and scare the living out of them!

Did that on my way to Virginia beach last year in traffic. Black girl next to me jumped and spilled her drink haha win!

Well, if I replaced my takeda mufflers with these, I wonder how loud it would be...also running hfcs. Definitely wouldn't have to worry about scraping my cans anymore lol.

Dead thread revival!! Here is a sound clip and a shameless plug --
