Upgrade Project - Installation of the Corsa Exhaust

 

by Scott Fabre

Last Update: 08/03/2005

 

Boxes as received.

Warranty information and instructions

were quite complete although some

attention could have been given to a

few "gotchas" that occur during installation.

 

Nicely packaged and wrapped.

Notice the attention to detail and

wrapping.

 

Spray in foam is used.

 

I felt like I should have to wash

my hands before handling these.

 

Yup, all parts are accounted for.

 

Ah, lifting the car again. I've been here

before. The trick is to not hurry through

this phase.

 

Very interesting fasteners, bands

and clamp arrangements.

 

The hangers are loosened. Four

mid section spring loaded hangers

and two rubber mounted hangers

at the rear attached to the muffler.

 

Next three bolts holding each bracket

on each side at the front.

 

The first tube to go in is the passenger

side after the stock flange is slid off.

Notice, the welded tab on the left above.

There is no captive nut as there is on

the stock exhaust assembly. Seems

like an oversight. I fixed this a few picture

below.

 

Passenger side pipe after the

stock flange was removed.

 

Sanding was advised in the instructions.

I would not have done this normally but

since the instructions said to....

who am I to not follow instructions.

 

Here is one of the nuts supplied with

the kit. It is not metric. That was

disappointing. What was even more

disappointing is me finding that I had

plenty of metric nuts and bolts this

size later AFTER welding the nut to the

tab.

Welded flange from the bottom

view.

 

Welded flange from the top view.

 

A view of the passenger side tube before

adding the "Easy Seal Clamp".

 

"Easy Seal Clamp" is installed.

 

Sanding the lip of the flange.

Both of the front tubes are in and attached

to the front spring hangers.

 

Bolts added to the driver side flange.

 

So called center muffler is

next attached (resonator)

 

A jack handle in place between the

differential housing and the center muffler.

 

Next the bands are added. (the

instructions said to put these on

first. I found this too clumsy to

do so I added them after) No big

deal. You just bend them apart to

fix over the pipe then use a large

pair of channel locks to

bend them back.

 

Next the "under the axle" pipes and rear

mufflers are hung. This was not difficult.

What was difficult was aligning

it all up. There were no hints on how to

do this. I just played with it till things

came into shape then tightened

everything up.

 

Finally, the last part is clean up

and finding a place to store the

old exhaust system. You can

see by how much of the system

is protruding that the storage

shelf I used was very deep.

 

 

 

The part that was not so obvious was to affix the very first pipes put on in the front (head pipes) such that the rear

part of the pipe was slightly lower than you would intuitively think would be correct. By doing this the rear pipes

do not touch the bottom of the differential case. This would be bad to find later since a vibration would then exist.

Jacking up the car again to fix this would very annoying.

 

In closing I would like to acknowledge that many of the things mentioned above came directly from reading the

ZR1NET. As I started the install and as I progressed through the project little things would pop in my head that

I had read in other post. The whole project was a piece of cake because of this.

 

I hope this was helpful. Who knows I may create a lot more prose to all this and send it in to be placed in the

Registry magazine.

 

Here is a link to pictures of a Corsa system that was delivered with a part that was the wrong size.

 

And here is an MPG file of the management crew recorded shortly after discovering the wrong part!
