Breeze Tech Tip #3 Roadster Side-Pipe Adjustment

Here is the conversation I have with anyone calling up to inquire about how to use our side-pipe wedges and spacers to align their side-pipes.

Bolt up the side-pipes if possible w/o hitting body then see how much you need to swing the tip of the pipe in or out from the body.
Wedges are 1/2", 1" or 1-1/2" and you can stack them. If pipe is parallel to body and just want to move it away then order the 1/4" spacer, also stackable.

Another approach is to position the pipe parallel to the body and even with the bottom of the 4" round chassis tubes and observe the gap at the flange front and back, top and bottom.
The 1/2" wedge tapers 1/8" to 1/16".
The 1" wedge tapers 1/4" to 1/8".
The 1-1/2" wedge tapers 1/4" to 1/16"
Placing the thick side of a wedge on top or bottom will lower or raise the pipe only slightly.
Gaskets add about 1/16" thickness.
Generally gaskets are not needed between wedges or spacers, just one each next to the header and side-pipe flanges.
If running Quiet-pipes cut the center out of the gasket since it is unsupported and could blow out and get caught in the baffle.
Remember you will need longer 3/8-16 socket head cap screws and if you are using wedges they may be different lengths ideally.
Breeze stocks them in stainless steel in 1/4", 1/2" and 3/4" longer than stock which are 1-1/2".
We prefer hex serrated flange nuts to the top-lock nuts that come with the kit because they spin on freely and then lock, rather than fighting you all the way.
Breeze offers the nuts as well for your convenience.
If you need to rotate the side-pipe relative to the header flange you can switch from 3/8" to 5/16" hardware to gain some clearance.

You can raise or lower the motor in the chassis by stretching the motor mount holes. Move the mount in and the motor sits lower. Move the mount(s) out and the motor sits higher.

Do not attach the inboard end of the FFR supplied side-pipe hangers to the frame. This needs to be free to move side to side. If they are attached the pipes become overly constrained and the end result will be cracks where the hanger tab is welded to the muffler shell. Just the rubber hanger attached at the "elbow" is sufficient to dampen large movements of the side-pipe.

Hope that helps!
