aFe 49-36615-L Takeda uses 2.5-inch into dual 2.25-inch 304 stainless tubing, dual high-flow mufflers and TWO welded blue-flame 304 stainless tips. Its 100% TIG-welded construction installs using five main assemblies, four bands and one NEW gasket. The exact manual expressly excludes LX and coupe models.
2016-2021 Honda Civic FOUR-DOOR SEDAN with 1.5L turbocharged four-cylinder. Current primary names EX/EX-L/Touring, and the own February 2021 manual explicitly states DOES NOT FIT LX OR COUPE MODELS. The old LX application row is removed on that express manufacturer exclusion, not merely because a trim is absent from a headline. Other original named-row years and gaps are retained; EX-T, Si and Sport legacy positive retailer records remain SOURCE CONFLICTS against the narrower primary wording and require exact vehicle/body confirmation. They do not independently certify a coupe, hatchback, 2.0L engine or Si bumper arrangement. No new broader retailer Type R, Sport Touring or later-year scope is added.

| Blue muffler selections | LEFT 05-145134; RIGHT 05-145135, with welded blue-flame tips |
| Tip dimensions | Current explicit DIAMETER 3.5 inch; overview 6 inch wording lacks independent dimension qualifier |

| Clamps / gasket | TWO 2.5 inch 05-41061; TWO 2.25 inch 05-41210; ONE new gasket 05-46192 |
| Original parts / battery | THREE front nuts, transferred rubber mounts; NEGATIVE BATTERY disconnected and reconnected |
| Torque / recheck | No numeric torque printed; ALL clamps and bolts after 50-100 miles |
| Marked chart gains | +8.51 HP/+9.03 lb-ft at differing marked RPM positions |
| Curve-max differences | +4.20 HP/+6.83 lb-ft |
| Dyno conditions | The exact linked chart accompanies the manufacturer's stated 2016 Civic Sedan Touring CVT test. Marked values show 153.76 versus 145.25 HP (+8.51 HP) and 162.93 versus 153.90 lb-ft (+9.03 lb-ft). HP and torque markers occupy different horizontal RPM positions; the displayed cursor near 4.95k rpm is not a common RPM label for all markers. Curve maxima are 181.67 versus 177.47 HP (+4.20 HP) and 179.16 versus 172.33 lb-ft (+6.83 lb-ft). Advertised 8 HP/9 lb-ft is not an identical peak-to-peak change. Baseline: September 9, 2016 at 10:22:52 AM, 84.81 F, 29.41 inHg, 36% humidity, SAE factor 1.02. Modified: January 9, 2017 at 2:21:38 PM, 64.77 F, 29.50 inHg, 64% humidity, SAE factor 0.99. Both notes identify OE intake system/downpipe, sport mode and VSC off. Modified notes additionally say OER FILTER and aFe exhaust, while baseline says OE exhaust without that filter note; equal filter configuration is not independently established. Dates are four months apart and conditions/corrections differ. Chart uses SAE correction and smoothing 5. Results do not certify all named grades or isolate an exhaust-only change. No actual bench-flow chart is linked. |
| Emissions | Current exact manufacturer states no CARB EO number is required for this cat-back. This does not authorize unrelated emissions-equipment changes or establish every local sound requirement. |

Reuse THREE ORIGINAL FRONT-PIPE NUTS and TRANSFER original rubber mounts. TWO welded-on blue-flame 304 stainless tips are part of the selected muffler assemblies; polished-tip mufflers in the shared bill are alternatives, not extras. Current primary explicitly states 3.5-inch tip DIAMETER; its separate unqualified 6-inch overview wording is not independently treated as a diameter or length specification. No new converter, sensor, valve, intake filter or intake coupler is listed.

Which body, engine and exclusions apply?2016-2021 Honda Civic FOUR-DOOR SEDAN with 1.5L turbocharged four-cylinder. Current primary names EX/EX-L/Touring, and the own February 2021 manual explicitly states DOES NOT FIT LX OR COUPE MODELS.

Other original named-row years and gaps are retained; EX-T, Si and Sport legacy positive retailer records remain SOURCE CONFLICTS against the narrower primary wording and require exact vehicle/body confirmation. They do not independently certify a coupe, hatchback, 2.0L engine or Si bumper arrangement. No new broader retailer Type R, Sport Touring or later-year scope is added.
Which blue-tip mufflers and tip dimensions are selected?LEFT 05-145134 and RIGHT 05-145135 contain the welded BLUE-FLAME 304 stainless tips. Current exact details explicitly state 3.5-inch DIAMETER. Separate overview 6-inch wording is not independently qualified as diameter or length. Shared polished-tip mufflers are different selections.
Is the front gasket new or reused?ONE NEW GASKET 05-46192 is supplied and used at Mid-Pipe#1. Reuse THREE ORIGINAL FRONT NUTS and TRANSFER original rubber hanger mounts. This own bill differs from other Civic kits that reuse an original gasket.
How many clamps and what installation sequence apply?TWO supplied 2.5-inch bands join mid1 to mid2 and mid2 to Y, per explicit steps 8/9. TWO 2.25-inch bands attach RIGHT then LEFT mufflers. Keep connections loose until complete system adjustment, then tighten.
What battery, torque and recheck instructions apply?DISCONNECT NEGATIVE BATTERY before removal and RECONNECT after alignment/tightening. No numeric torque is printed. Start and check leaks. Re-tighten ALL CLAMPS AND BOLTS after 50-100 miles.
Do advertised gains equal peak-to-peak gains?The exact linked chart accompanies the manufacturer's stated 2016 Civic Sedan Touring CVT test. Marked values show 153.76 versus 145.25 HP (+8.51 HP) and 162.93 versus 153.90 lb-ft (+9.03 lb-ft). HP and torque markers occupy different horizontal RPM positions; the displayed cursor near 4.95k rpm is not a common RPM label for all markers.

Both notes identify OE intake system/downpipe, sport mode and VSC off. Modified notes additionally say OER FILTER and aFe exhaust, while baseline says OE exhaust without that filter note; equal filter configuration is not independently established. Dates are four months apart and conditions/corrections differ. Chart uses SAE correction and smoothing 5. Results do not certify all named grades or isolate an exhaust-only change. No actual bench-flow chart is linked.
Are emissions clearance and sound unconditional?Current exact manufacturer states no CARB EO number is required for this cat-back. This does not authorize unrelated emissions-equipment changes or establish every local sound requirement. No decibel level or cabin-drone guarantee is supplied.

Other unresolved positive grades remain qualified, without new scope expansion. The primary unlabeled 6-inch tip wording does not override its explicit 3.5-inch diameter or establish a separate length. Polished-tip mufflers and OER intake filter mentioned in dyno notes are not extra included parts.
