Just last night i was driving and when i'd stop at a stop sign at start to go at around 1000 rpm a rattle came from underneath the car, it was late so i didn't get a chance to look under and i haven't today but i was thinking maybe the exhaust hanger came loose? I'm pretty sure its the exhaust its souns like metal vibrating on metal, my exhaust is loud so i could only faintly hear it at around 3000rpm which seams to be the the highest rpm for most vibration from the exhaust. so what do u guys think it could be.

 

Do you have the stock exhaust system, or a replacement?

The reason I ask is, the extra hot & sharp exhaust pulses from a rotary engine will bang the baffels loose in standard silencers & mufflers.

This is especially true for NA's with headers.

 

Probably a heatshield

 

i've gotta magnaflow gt custom dual exhaust with magnaflow canisters

 

Ditto...Check around the junction points of the first two heat shield sections- they like to rust out there...

 

hummmmmm crawl under it and look!

 

I have the same problem and also Magnaflow mufflers. I’ve been under the car and I can’t get it to rattle. Visually it looks fine with nothing broken off.

 

did ur rattle start out of the blue or its always been like that.

 

Used to have a rattle. Turned out to be the air return line vibrating against the forward heat shield. Used some picture wire to secure the arl and that was the end of that.

 

What the duece... I figured bungee straps would have been your fix amur maybe a little ductape

 

You're still not funny...
