Exhaust Vibration I SEARCHED

[SkullV]

So, I installed my Magnaflow cat-back this week and I am LOVING it. The only problem is that no matter how I adjust it it still vibrates on the little tiny crossmember that goes below it. Is that crossmember necessary or can I just remove it and not worry? I remember reading about this somewhere but no matter how hard I searched I couldn't find it.

Thanks!

I have the exact problem on my newly installed Magnoflow. About 75 miles on them so far. In an earlier post I was told that it was not necessary. My virbration and noise comes from sharp turns, reverse, and when the car needs to be downshifted. I was going to do the adjustment and tightening tomorrow and take the bar off. It is a little embarrasing when everyone hears your exhaust and then you turn and screetch into the parking spot.

At least the smell is gone!!!

Remove it.

Is that going to be a problem with the dealer for warranty work?

I doubt it.

It is just a bracket to keep the exhaust from falling away from the car.

Several years back, I had a set of race headers on a Miata blow the main collector weld. The entire ehxaust from the collector back pivoted down (mufflers pointing skyward, front pipe toward the ground) and get caught on the little "useless" cross bracket below the car. Had it not been there, I probably would have become the world's first Pole-Vaulting Miata (at worst), or at least had the whole rear of the car torn off when the pipe caught the pavement (at best).

Do what I did: Bend it down, but leave it installed.

That sounds a lot more intense then a "stick in the spokes".

ya, I took mine off as well...if you really want to leave it get some header wrap and put that around the pipe and/or the cross member.

When mine first went on the center section was put in upside down so that little cross member was on top... Very noisy until I insisted the guy the section out, turn it over and put it back in. I think I had him leave the factory support off as well.

I would leave it on as its support. What I did, and I dont have the vibration. Is took some of that black tar like sound deadening material (dont know what its called) and put a descent amount between the pipes....
no vibration
10k miles later.....still no vibration.

I took mine off. My KARS kit would catch it if the exhaust broke away.

dynamat?? hows that hold up to the heat?? I'd be worried about that stuff catching fire (mainly because I dont know what it's made of)

[04CTSVFLA]

Its been fine....Its a tar like substance, doesnt catch on fire. It does get a little softer when heated...but not enough to move from where Ive placed it. Im actually going to buy some more today...

oh and im in pb gardens for a couple days nikon.

Not sure how the Magnaflow comes, but the Corsa is in a bunch of individual sections. If not bolted up tight, it does the same thing ... drives me crazy.

I have to loosen it up from one end to the other, jack it up against the bottom of the cabin, then tighten each clamp. If done right, it works great!
