Exhaust Popping off when going WOT in 1st...

[jmillsUT28]

I have a corsa exhaust and if/when I go WOT sometime the exhaust pipe in front of the passenger wheel pops apart. I connect the pipes again and tighten the clamp down but it still pops out. It has only happened in 1st gear when I really get on it from a slow roll. I guess I could just stop doing that... Really no need to as I have no traction at all in first with new tires. I think one of my problems might be that the pipe only goes into the other maybe 1/2". Anyway to fix this?

Yes it's a upside down picture.

Time to weld...

Well Mike I was thinking J-B Weld... haha

I have a welder so I might just weld it in a few spots.

New motor mounts?

 

[jmillsUT28]

That might be a good idea. Not sure if these have ever been changed out. The car almost has 50K miles with a built engine and Paxton so maybe...

1. Engine/Trans mounts. Go with something better than factory.

2. Widen slots on the "slip-over" section of the pipe.

3. Re-Clamp.

4. DRIVE.

motor/trans mount

+1 for motormounts, and slap a wide bandclamp over that connection to seal her up

i had the same thing happening on my GTS when i first got her

That's the pipe in front of the rear tire?

If it was a motormount problem I would expect the front section of pipes/cats/muffler would pull apart if the exhaust was built and/or installed properly. I'd suspect that the rear section is too short and doesn't fit into the joint far enough. Clamp? There's no clamp or clamp markings on the pipe. The pipe looks like mild steel (rust spots?). I wasn't aware that Corsa made a mild steel exhaust system?

Well I thought it was a Corsa. I bought it from a dealer and all of this was already installed on it. Does corsa have a stamping somewhere with their name?

 

[plumcrazy]

few tack welds and clamp ?

 

[jmillsUT28]

Yea Phil, I think I am going to do that for the time being. Then take a look at the mounts.

I think the 4" tips have the name? You'd have to call Corsa and ask them.

Definitely do the motor and trans mounts now. Might want to get up with Mark J from Woodhouse for the Poly engine mounts. I thing Jegs has the tranny mounts.

 

[jmillsUT28]

I think Mark has them both. I'll give him my business as he hooked me up when I was getting my Paxton rebuilt.

Woodhouse has the trans mount too. I have heard of aftermarket mounts being a different height than stock. The woodhouse mount is the correct height.

What I don't like is the vibration from the poly mounts....some say it goes away but gezzzz it's bad when they are new. Maybe due to the trans mount. I have solid steel motor mounts and no vibration like the two cars I have installed poly's on.

Are you saying that there's less vibration with solid steel mounts than with poly mounts?

 

[1TONY1]

Less with steel motor mounts and stock trans VS poly motor AND trans mount. That's my car VS two cars I have done poly mounts on.

I just did one this week and drove it with the poly trans mount only and it definitely vibrated, I'm not sure it got any worse after the motor mounts were done. I do know that the trans mount is right under your butt.

But it seems like everyone says the vibration settles down after 500 or so miles. We will know in a few weeks.

When you Change the mounts also change the clamp as it is stretched out. I did this and have had no problems since.

Yes, we WILL know in a few weeks. Some of that vibration may be from the tires. When I brought it to you, car had been setting for about 3 months. Extreme flat spots on the tires. It did smooth out some on the way down though. I'm putting the KDW's on this week, so we'll know for sure. See ya in a few hours

Sorry Jon,
back on track everybody.....
