Exhaust cut-out causing rattles?
Exhaust cut-out causing rattles? Hey guys, I've been playing around with my cut-out and I've had it opened for about a week and it seems to vibrate my car more and it's causing a rattle in my drivers door and in my shifter? Just wondering if anyone else has had problems like this or if my exhaust is just a little loose or something along those lines? I love the way it sounds with it open and the extra bit of power but I hate rattles and I'm wondering if it's worth it to keep it open? It only seems to rattle when the cut-out is open and when it's closed there's not one rattle.
i just got my cutout on yesterday, i usually dont leave it open too long, just short instances here and there, its awesome and no rattling of anything.
SO i wonder if leaving it open too long can cause the rattle?

when its shut, the pressure from the exhaust is pushing on the plate and it can loosen it enough to let some air out and itll sound like ****... any exhaust that exits underneath the car is bound to rattle something.. is it mostly at idle or light acceleration?
It's all right at light acceleration. It doesn't rattle at idle or at cruising speeds or even at full throttle. I love the sound of it, you can hear my cam a lot better and it's a lot louder which is the way I like it but I don't want any rattles either.

i have LTs ORY, and i run my cutout open all the time now. Yes my center console vibrates now, but its worse when the cutout is closed and the exhaust flows hits my restrictive flowmaster, the resistance causes everything to vibrate!
I believe it's the placement of the cutout that causes the rattles in the cabin. Mine is in the I-pipe right behind the passenger seat and when I run it open, I get all kinds of rattles. Don't get me wrong, it sounds good at WOT and idle, but anything else and it sounds like 
It's to the point where i'm thinking of moving it behind the axle. There's a perfect spot where the I-pipe goes into the muffler. I'm thinking this might cut down the amount of rattles and drone.

Mine is in the factory catback just before the pipe goes over the axle and yes mine has a rattle or two with it open. The resonance of the exhaust uses the car as a bass drum effect and the sound waves jars stuff a little and creates rattles. I have shorties so its not well defined in the sound arena 
but does sound awesome cruizin at 3500 rpms on the interstate

The increased sound energy near the cabin is only the
stimulus, you have to find the loose material that is the
"pickup". Just like some songs are better than others at
showing you a blown speaker, the speaker is still blown.
