Invidia midpipe
Hey I have been looking around and because I recently put in my invidia midpipes and there's a rattling sound. I've read that people used washers but where do we put them?

Mine was rattling when I first installed it and it sounded really raspy too. After looking, I noticed that the pipe wasn't perfectly lined up the the middle where there are the four bolts. Make sure it's perfectly lined up there and all bolts are tightened. The rattling either is from loose bolts or the pipe hitting the rear link bar. Check how it fits and tighten the bolts that connect it to the axle-back really tight. Ever since I adjusted the pipe and tightened the bolts, never have I heard rattling again.

It seems some of the Invidia's do hit the rear bar. Mine is supper close. Everything is good and tight. It just sit's really close to the rear black bar. I've got a washer on each. Some people say they had to add a few more. Mine just hit's on large bumps.

I had the rattling sound when it was first installed.. I actually took it back to the shop where the installation was done, but they said everthing looked right.. then a few weeks later the rattling was gone.

Yup, mine was also rattling when I first installed. Ever since I installed the washers (been about 4mo now) it's been rattle free. I do suggest that you rattle can the washers if you didn't pickup stainless steel ones. They tend to get rusty and gross quite quickly.

Dual resonator vs single
Hi there, new lex owner looking into invidia midpipe. Notice there is a more expensive dual resonator version and then a cheaper single resonator version Whats the difference? Sound? One better than the other?

Someone correct me if I am wrong, Single resonator is the 2IS version and the Dual resonator is for the 3IS. The 3IS is a little bit longer than the 2IS

Sorry need a little hand here. I just bought mine last week. Tried to do it myself but I figured I'm gonna need a lift so I asked one of our local shops and they said they don't want to take out the o2 sensor with the special tool for it, rather they want to unplug it from the inside. It's gonna cost me like $300 for labor. Is there any certain way to take off the o2 without doing all that work?. They don't wanna take it out from the bottom coz they're afraid that they might damage the sensor or the wiring.
