Downpipe rattling against the subframe.
 

So i thought it was because of the engine mounts or the transmission bracket that holds the stock exhaust. Yesterday i got brand new mounts in and removed the tranny bracket. No luck, the downpipe is still rattling against the subframe. Any ideas?

This is the begi s kit with the regular non separated gasses dp.

bend it? lol

U mean smash it with a hammer? I'm trying to avoid that since its only a 2.5" pipe.

sawzall? grinder? jaws of life?


can you clock the exhaust housing a few degrees somehow? mine rattled and still does sometimes but i have vband so i can rotate the pipe and clamp it in place again.
you can use exhaust wrap on the spot it rubs to stop the noise at least

maybe if you cushioned it with something like a bunch of heat wrap or something fire resistant.

Sucks, surprised to see this seeing as though you have both the begi manifold and downpipe. I would try throwing some heat wrap around it as well, might make it tolerable....

Hi there,
Sorry for the late reply, I've been out with pneumonia. First, I would make sure you have the right down pipe. Did you get it new or used? If new, you can loosen all fasteners, wedging something between the subframe and the downpipe, then re-tighten the fasteners. If that does not work, give me a call and we will figure it out. If the pipe is used, can you post some photos and details of your car? Exhaust systems details too please.
Thanks,
Stephanie

It was used. Its the begi s kit.

Try what Stephanie said first, if that doesn't give you enough clearance then see if clocking the turbo a small amount helps. One mm on top could be like 5mm on the bottom.

One cannot clock the turbine as its directly attached to the manifold.

I will try what Stephanie said once it stops raining since its like the rapture out there.

So today i found the problem. Its rattling against that pipe that connects both sides of the subframe. Any reason keep it or can i get rid of it?

Stop posting.
You're an idiot too.

you either shim the engine mount or you sent it back to BEGi to get it fixed.

That's a pretty sweet image! Need to powder coat the control arms and subframe silver!!!

And I would keep that pipe. Could you perhaps use a couple of washers behind it to space down a bit?

That is not my image. Was just a random image i found on google.

I was thinking about washers too.

I have a BEGI-S SSSG downpipe that is also a hair away from that bar.
I'm going to add washers too.

Well today i fixed it. I loosened the bolts on the turbo/dp. Used a C clamp to grip the flange and twist it and tightened the bolts. That gave me about half an inch or so.

Now that was done but noo i wasn't stopping there. I lifted it so i'mma beat the crap out of it at least for annoying me all winter. I took off the pipe on the bottom and had my way with it.

You can see the paint all gone from where it was rattling. The dp had a shiny spot on it too.

It has washers on each side so i took the washers from the passenger side and used them on the drivers side as well.
I also beat the shit out of the pipe, put it together and it looks quite dandy now.

BFH! BFH! BFH! ...

If the down pipe hits that brace, the best thing to do is add some washers the brace mount or flatten the brace some. We just modify the braces here so there is adequate clearance.
