Annoying Rattling

NismoZ370 · 11-21-2011, 01:49 AM

Those worked great I ended up using 4 on each bolt (may seem excessive but i didn't want to have to redo it later!) and no vibration or rattle noise at all I'm so happy with exhaust now!!!!!!!!!!

I'll have to check my HKS out, I have the same raddle going on with my nismo, it starts around 4K while the engine is under load. It won't do it if I just rev the engine, just during acceleration. I was starting to think it had something to do with the engine vibration being transfered to the exhaust. I'd love to get this corrected.

its probably the same thing on my nismo the metal beam a little further back from the y-pipe section. i put 4 washers on each bolt in between the metal bar and the car and its perfect gave me about 1/2" - 1" gap no more annoying rattle.

Does anyone have any pictures of this brace that the washers are going on??

NismoZ370 · 01-20-2012, 03:20 PM

It's black flat piece of metal right in front of the wheels you can't miss it. I don't have pics though

Does this seem to be a problem with all full cbe exhaust or just one that sit closer to this "brace"?

Only certain brands.

The brace you are looking for is the black brace that is near the rear-center of the car. You can see it really well in this pic (found online). There are (4) bolts that attach the front of this brace that can have washers added to give the exhaust more clearance in this area.

I personally used (3) stainless fender washers under each of these bolts this weekend, and it made a HUGE improvement in the rattle issue I was having. I honestly think my Ark DTS was resting on this brace slightly after I added Berk HFC's. It rattled a ton and basically sounded like crap until I added the washers. Now I love to drive my car again!

Installed my Berk HFC/CBE setup and have this problem. Glad I found this thread! I will do the washer trick this weekend. Wish I had known this would be an issue or I would have fixed it during installation.

It could be the hangers that hold your exhaust together.

I may have to try this, sometimes when I hit a certain rpm I get a nasty rattle for a second, I thought maybe it was a heat shield that was vibrating.

I had that too Huck, turned out to be my license plate rattling against the body! Only happened from 3600-3900 rpm.

An easy fix that I did for my Berk cbe was to take some pipe clamps and put them over the rubber grommets on the hangers and crank them tight. A jack was used to lift the exhaust prior to tightening them up. It gave me a fingers width clearance from the brace and has been good now for the past 6 months.

Thanks for the input! This IMO is a better fix than adding washers to the cross member bolts....

I just finished doing exactly as you described and it worked to perfection!! A quick 20 min fix and no more rattles for me!!! Thanks again!
