So here it is, a video finally of what this bad boy actually sounds like
But first off, a quick rundown of how it was installed:
1. Unbolt and take off y-pipe and decat pipes
2. Cut about 8 inches off of each decat pipe so the y-pipe can be shifted up to give room for the QTP y-pipe + bypass valve
3. Cut flanges off of the end of the 8 inch cut off decat pipes and weld onto end of shortened decat pipes
4. Bolt shortened decat pipes back on and bolt y-pipe back on
5. Weld in bypass valve + y-pipe where the gap is
6. Wire up bypass valve to a power source (in my case, the headunit) and feed switch into car (in my case, through gear gaitor) and place wherever tickles your fancy, i've personally had it installed in the cubby hole below the headunit so it's out of the way
And that's pretty much it, there was a bit of tweaking here and there but that's the basics of how it was installed, the bloke who did the work knows more (a lot more) than me
Here's a quick vid of the install so you can see in the flesh what's actually been done:
And here's a vid of what it sounds like in comparison to normal
This vid doesn't do any justice for how loud it actually is (as the mic automatically dumbs the sensitivity down to prevent distortion), nor does it do any justice for how f***ing awesome it actually sounds, but you get the idea
But there we have it, the QTP bypass valve and how it sounds attached through a VQ35DE. Hope you like it, i know i certainly do
