Which engine years and hybrid application are supported?2018-2026 Subaru Crosstrek per current exact primary and own September 2026 manual. Manual separates 2.0L 2018-2025 from 2.5L 2021-2026. Exact selected-part engine table identifies Base 2.0L through 2025/2.5L2026, Limited 2.0L2018-2020/2.5L2021-2026, Premium 2.0L2018-2024/2.5L2025-2026, Sport 2.5L2021-2026 and Wilderness2.5L2024-2026. Retained Hybrid2019 has exact retailer positive 2.0L evidence; later hybrid years/new hybrid grades are not inferred. Match actual flange, mounts and underbody layout; cat-back manual does not establish Impreza fitment.
Is a decorative tip included?No. Optional black49T25404-B08, polished49T25404-P08, carbon49T25404-C07 and blue49T25404-L07 tips are separately sold. Bare supplied outlet does not imply four included tips.
Does this include both muffler and resonator?Yes. Three main assemblies include a resonated front pipe and rear muffler, plus mid-pipe. Exact primary specifies 14-inch muffler and12-inch resonator. This is not the standalone muffler-delete axle-back.
Which gaskets and hardware must be checked?Reuse original converter-flange bolts/gasket and rubber mounts. Bill lists ONE 05-46300 gasket; step 12 x2 supplied gasket/bolts/nuts wording is ambiguous and separate bolt/nut identities are not itemized. Confirm actual boxed quantity and hardware before disassembly.
What torque, cutting and recheck apply?Supplied2.5-inch BAND clamp requires 40-45ft-lb. Flange-bolt numeric torque is unprinted. No cutting step is supplied. Re-tighten clamps/hardware after 50-100 miles.
Are9 hp/13 lb-ft gains changes in peak output?No. At3705 rpm annotated differences are 9.1 hp and13.0 lb-ft. Separate run maxima differ 5.9 hp and6.5 lb-ft. Those are different comparisons.
Are hybrid power gains or drone-free sound measured?Actual chart is2018 Crosstrek with stock intake and second gear, on different dates; engine displacement and several conditions are unprinted. It does not certify2019Hybrid or later-engine gains, nor a measured drone-free cabin.
Verify aFe 49-36803.

OBD2 RPM, Dynoware RT WB, Linx CONNECTED, smoothing5; numeric correction factors, engine displacement, fuel, weather, hood and load are unprinted. Advertised9 hp/13 lb-ft approximates point gains, not changes of separate maxima. No actual flow or measured cabin-drone chart is linked; virtually-no-drone description is not a guaranteed measurement. Later hybrid fitment is not inferred from shared engine size.
