PYPES SFM88MS Mustang GT Axle Back
Product Information
The SFM88MS and SFM88MSB are axle back systems designed for the 2018 Mustang GT. They come with the following components:
- TFM88 Tail-pipes: 1 piece
- YFM87 Y-Pipes: 1 piece
- EVT57/578 Tips: 4 pieces
- HVC21 Clamps: 2 pieces
- HVC24 Clamps: 2 pieces
Product Usage Instructions
- Begin by placing the vehicle on a lift or four jack stands at maximum height. This will aid in an easier installation.
- This axle back system installation does not require removal of the factory exhaust. Cut the factory system close to the bend that leads to the muffler. This will give you the maximum amount of material for adjustments.
- Begin your installation by cutting your factory system and removing the mufflers. It is critical to cut the factory system as shown above. This will leave you with the maximum amount of material to make adjustments to the system.
- Start the installation of your new Pypes system with the TFM88 tail pipes using the HVC21 band clamps, clamped to the factory system followed by the YFM87 pipes. Tighten just enough so you can align and mark your final tip locations in the valance.
- Align the tips in the valance and begin tightening them along with the clamps. We found that marking the tips for depth and alignment first and then tightening them to the Y-pipes off the car is the easiest way and will give you the best results.
- Once you are satisfied with the alignment, finish tightening all clamps. The use of hand tools are highly recommended for this step.
- Now the clamps are tight, start up your Mustang and check for leaks.
Note : When tightening the HVC21/24/25/26 band clamps, make sure the I-block in the center of the clamp is against the head of the bolt. Failure to do so will cause the clamp not to tighten properlyor the I-block to break.
READ THIS WARNING!
- Make sure you test fit these exhaust components BEFORE any cutting, welding or unnecessary bending is done. Once modified, the components of the system are NOT RETURNABLE.
- If you are unsure of the proper installation procedures or fitment, please contact a qualified exhaust shop or call our tech lines toll free at 800-421-3890 or visit our installation gallery at: www.pypesexhaust.com/install
