FE1-6-105 11th Gen Sport/LX Exhaust

First and foremost; THANK YOU for becoming a part of the 27WON Family. We hope to REDEFINE your experience of the aftermarket with the highest level Parts, Customer Service, Packaging, & Support

These instructions were written with a 2022 Civic Sport Sedan

Jack up your 11th Generation Civic and place your jack stands in the appropriate mounting spots

You can find this in your owners manual

Make sure you have supported your car properly. If done improperly, this could lead to serious injury

The following instructions are shown with no bubble wrap or cardboard for clarity of the installation process

We recommend leaving as much protective bubble wrap/cardboard on the exhaust as possible during install to protect against scratches and dings during the process

Cut holes in the bubble wrap to expose the flanges, hanger rods, and fastening locations

The 27WON packaging is not only designed to get your performance parts to your doorstep safely, but to also provide you with an awesome garage banner and/or comfy cardboard mat to lay on under your car for installation

You can cut out the banner as shown with the orange square

Or you can use the entire unfolded box as a mat to lay under your vehicle

Remove the staples from the box as they don't feel great on your backside...

Locate the Skidtray

We recommend using a prying tool like the one shown by the green square

Use a flathead screwdriver or a prying tool to remove the fourteen (14) plastic push-clips circled in orange. Orange arrows identify the eight (8) additional push-clips described in the next step that are removed last

Use a #2 Philips head screw driver to remove the two (2) Philips pan head screws shown in red circles

Use a 10mm socket & ratchet to remove the two (2) short head shoulder bolts shown in dark blue circles

Use a 10mm socket & ratchet to remove the four (4) tall head shoulder bolts shown in light blue circles

Use a large flat head screw driver or prying tool to remove the four (4) push-clips from each front wheel well

Remove (4) 14mm bolts shown then the bracket for easier access to the front pipe flange

Support where the exhaust meets the front pipe with a bungee cord

Using a 14mm socket, remove the (3) bolts shown

We'll show each hanger in the next steps. Hangers can be very difficult to get off. Here are a few ways to approach this

Spray hanger as shown with lubricant. We like glass cleaner

Using your Tongue & Groove Pliers, pry the rubber bushing from the metal hanger

Or, the easiest way is to use exhaust pliers. You can get these on Amazon for around $20

Using a spray cleaner, lubricate the front hangers and rubber support

Use tongue & groove pliers to press the rod out of the rubber hanger. Remove the hangers of the exhaust from the rubber supports as shown

Using a spray cleaner, lubricate the rear hangers and rubber supports

Use tongue & groove pliers to press the rods out of the rubber hanger, then remove the hanger off the exhaust from the support as shown

Using a transmission jack, floor jack, or a friend support the OE exhaust as shown

Using a spray cleaner, lubricate the remaining rear hanger and rubber support

Use tongue & groove pliers to press the rod out of the rubber hanger then remove the hanger off the exhaust from the rubber supports as shown

If the exhaust is unsupported, it will fall and possibly become damaged. If not done yet, make sure you support the OE exhaust

With the exhaust unbolted and removed from the hanger supports, remove from the car and set aside

Using a spray cleaner, lubricate the front hanger and rubber support as shown

Use tongue & groove pliers to press the rod out of the rubber hanger, remove the rubber support off the OE exhaust hangers

Reinstall the rubber support on the 27WON forward mid-pipe hangers

This step could be done on the car. For reference, it is shown off the car here

Align the two mid-pipes as shown. Their orientation is critical for proper exhaust fitment

Use the hangers for reference

Insert a provided "tri-bolt"gasket between the two flanges of the mid-pipes

Align the flanges as shown

Perfect alignment of the flanges here is critical. Even 1mm of misalignment can cause a big fitment issue at the rear of the car

Make sure the exhaust flanges go where the green arrow is indicating when installing your hardware in all flanges in your 27WON exhaust system

Install 3 sets of hardware as shown using a 17mm socket and 17mm wrench. Hand tighten the hardware for now

Using the same location as before, support the back of your 27WON exhaust with a friend or jack

Place forward mid-pipe on front pipe studs as shown. Support the front section with a bungee cord in case it slips off

Using a spray cleaner, lubricate the rubber hanger

Reinsert the front hanger to the chassis hanger as shown

Using a spray cleaner, lubricate the hanger support

Reconnect the rubber hanger to the exhaust hanger

Remove Bungee Cord near front pipe

Locate QTY=3 provided step nuts

Locate QTY=1 provided tri-bolt gaskets

Locate QTY=3 provided 35mm length M10 bolts

Perfect alignment of the flanges is critical. Even 1mm of misalignment can cause a big fitment issue at the rear of the car

Install the provided "tri-bolt" gasket onto the OE front-pipe

Align the studs through the flange then hand tighten the step nuts

Reinstall (4) bolts as shown to secure bracket

Use caution not to damage exhaust tip

Using a spray cleaner, lubricate the hanger support for the muffler section

Reconnect the rubber hanger to the exhaust hanger as shown

It's ok to allow the muffler section to hang on the rubber support while you get the hardware for the flange

In one go, insert a provided "tri-bolt" gasket between the rear mid-pipe flange and the muffler flange then insert a bolt and washer to hold the sections together

Perfect alignment of the flanges is critical. Even 1mm of misalignment can cause a big fitment issue at the rear of the car

Align the gasket and flanges properly and insert the other two (2) bolts

Using the same hardware stack up as before, install the washer, split washer, and nut for each bolt

Hand tighten the (3) nuts

Stand back several feet from the car and inspect the exhaust

If the tip is sitting high, there may be a rubber hanger that is upside-down. Verify that all hangers are oriented correctly

If the tip is not centered, starting from the rear section, loosen the flange bolts and nut hardware moving down the system and re-align the flanges as needed

It can be tricky to get all the flanges just so. A very small fitment difference at the front pipe can make a big difference to how the mufflers hang

Once tips are centered, torque down all hardware to 25~30 ft lbs

Check again that exhaust tip is positioned properly

Reinsert the (4) push pins into the mounting spots as shown

Repeat this step on the other side

Reinstall the fourteen (14) plastic push-clips circled in orange

Using a Philips head screw driver, reinstall the two (2) Philips pan head screws shown in red circles

Using a 10mm socket and ratchet, reinstall the two (2) short head shoulder bolts shown in dark blue circles

Using a 10mm socket & ratchet reinstall the four (4) tall head shoulder bolts shown in light blue circles

Start the vehicle to check for leaks or rattles. If none, then take a spin around the block for further verification. If you do find a leak or rattle, please inspect the exhaust further

A leak could be caused by a loose flange bolt, improperly used gasket, or if debris is stuck between the gasket and flange

A rattle could be caused by misaligned pipe or a rubber hanger being orientated incorrectly

If you have "exhausted" all options, then give us a call and we would be happy to help resolve any issues

Exhaust may smoke for the first 30 minutes or so of use. This is normal

Exhaust sound will settle a bit during the first 100 miles of use. This is normal

Your Honda has a cold start system which causes louder exhaust for around 15 seconds when you first start your car

This completes the installation of your 27WON Performance Exhaust

We hope you were impressed with your 27WON experience and love your new exhaust system for years to come. Email us at sales@27won.com or call us at 571-271-0271 with any questions or concerns
