How many of ya'll have had a bunch of squeaks and vibration after installing LM1 catback? I have climbed under my car, and it is not rubbing anywhere. Also, I tightened all the nuts/bolts. The vibration is still there! HELP!!!!

What other mods you got done to the car, and did you install anything when you did the LM1? Also what kind of vibration, and does it feel like maybe the exhaust is shaking to much?

It has a pretty good amount of vibration because the muffler is right under the pass rear seat. I like the sound of mine but being lowered it hits alot. Aftre my H/C swap I am going to have a true dual system built.

Its been my experince that the band clamp is shitty and you should use a u-bolt thing. That quieted mine down a lot.

Well i did notice a good amoutn of vibration coming from the LM1 when did buy my car (was already installed). But i noticed most of the vibration from the passenger side, but then again i probbaly had to much fun driving it to notice any vibration.

mine is too and it will stop if i put it in neutral so i think since everything is tensioned up it is causing it to vibrate so if anyone can help it will greatly appreciated

Same here bandit. Mine is an A$ and it mainly squeaks when it's in drive at a stop. In park it doesn't do it.

I had a similar problem with my LM2 in which the over-axle pipe was rubbing against the axle. Traced the problem to the oem hanger on the LH side which was worn, replaced it with a metal hanger and o-clamp setup - eliminated the problem.

A year later when I installed a energy suspension transmission mount, the vibration came back again. This time it was that the heat shield for the fuel tank was rubbing the bracket by the over-axle pipe - bent a small section of the heat shield away from the pipe - problem solved.
