Ok so let me give you all the break down.. My exhaust set up is cnt hfc and top speed pro1 exhaust (single midpipe design) and thats it no other breathing mods or anythng... Ive have the exhaust on since June of this year and the hfcs since October.


the exhauast has sounded the same since day one, and obviously became louder after adding the hfcs. So today I was out getting a few things done (oil change, gym, shopping, and washed the Z). Not once today did I even get a chance to really push the car was in traffic a lot.

Now the weird stuff!!

So I gave the car a wash (hand wash) and after I finished up and started the car up to pull into the garage to my complete surpise my exhaust suddenly was about 5 times louder then it was 30 mins before I washed the car!!

At first I thought it was nothing, but when I revved it and actually drove it HOLY S*** its loud!!!! Not like a loud of and exhaust leak or crack in the pipe or anything but take the tone it use to be and raise it by 5!

I got a little worried and rushed over to my local tuning shop (JDS Motorsports) to have them throw it up on the lift and see whats going on. After a quick run down they found nothing wrong with the exhaust every bolt from the 3 bolts on top of the cats to the rear section was as tight as can be...

Im so freaking confused and worried as to what could of happened? Are my mufflers blow out? is that possible? Did the exhaust simply break in and this is the tone its suppose to be? I will post a video once i get the chance..

Please can anyone help!?!
