The aFe 49-37012-P Takeda axle-back uses 3-inch to 2.5-inch mandrel-bent 304 stainless tubing, MIG welds and an integrated mitered merge collector. Two 4.5-inch polished 304 stainless clamp-on tips carry laser-etched Takeda logos. Current exact manufacturer application is gas turbo 1.6L Veloster, 2019-2021.
The current exact manufacturer and selected guide identify 2019-2021 Veloster turbo 1.6L. The independent full exact-part named table confirms both original scopes and the missing Turbo Ultimate range restored below. No naturally aspirated Veloster, 2.0L Veloster N or earlier-generation application is inferred.

| Detail | Value |
|---|---|
| Manufacturer Part Number | 49-37012-P |
| Product type | Axle Back |
| Main construction | 3-inch to 2.5-inch mandrel-bent 304 stainless, MIG welded and mitered merge collector. |
| Selected tips | Two polished 304 stainless 4.5-inch clamp-on tips, 49T25454-P07. |
| Assembly and flange | Selected 05-145899 axle-back, new 05-46300 gasket and supplied two bolt/nut pairs. No separate new rear muffler in formal bill. |
| Hanger brackets | Passenger 05-46435 and driver 05-46436, attached with four supplied 1/4-20 screws and four nylon-insert locknuts. |
| Torque applicability hold | The selected guide prints a generic 40-45 ft-lb band-clamp setting, but the formal bill lists no separate band clamp and does not expressly assign that setting to the tip-fastener arrangement. Confirm correct tip-clamp applicability with aFe before applying it. It is not a flange-bolt, bracket-screw or universal fastener torque. Use correct separate settings, align then tighten front to rear, and retighten all clamps and hardware after 50-100 miles. |
| Dyno context | The primary claims up to +8 hp/+8 lb-ft. At the linked chart marker of 5,341 rpm, axle-back versus baseline values are 181.10 versus 173.21 hp (+7.89 hp) and 184.18 versus 176.13 lb-ft (+8.05 lb-ft). Separate peak power differs by +6.40 hp (191.18 at 5,850 versus 184.78 at 5,800 rpm). Peak torque is LOWER by 7.91 lb-ft in the axle-back run: 221.24 at 3,810 versus 229.15 at 2,960 rpm. A positive marked-point difference is not a peak-torque gain. Both run notes specify aFe cold-air intake, stock wheels/tires, Sport mode, traction control off, fourth gear, 2,000-rpm start and blade fan; SAE 1.00 on February 19, 2020. Baseline is 1:14:20 PM versus axle-back 10:44:18 AM. The visible chart does not print selected production part number, finish or vehicle model year; no stock-intake or finish-specific guarantee is inferred. |
| Sound and emissions | Manufacturer describes a throaty sound without a measured noise level or drone-free guarantee. No CARB EO required per selected primary is not whole-vehicle approval. |

It is the selected 304 stainless axle-back for the 2019-2021 Veloster Turbo 1.6L named applications, with two polished tips, a new gasket and two hanger brackets.
Does it include the separate mid-pipe?No. The selected bill is an axle-back assembly and its gasket, hardware, brackets and tips. The related mid-pipe is a separate product, not included content.
What components are supplied?one axle-back assembly 05-145899, one new gasket 05-46300, two M10 nuts 03-50189, two 10mm hex-head cap bolts 03-50452, passenger bracket 05-46435, driver bracket 05-46436, four 1/4-20 serrated hex-flange screws 03-50100, four 1/4-20 nylon-insert locknuts 03-50073 and two selected polished tips 49T25454-P07. The shared finish alternatives are not eight supplied tips.
Which gasket and factory mounts apply?Use the supplied new 05-46300 flange gasket and supplied flange bolts/nuts. Retain factory rubber isolation mounts; do not borrow original-gasket reuse or two new isolators from the earlier Veloster kit.
How are the hanger brackets installed?Install distinct passenger 05-46435 and driver 05-46436 brackets on the selected axle-back assembly with the supplied 1/4-20 screws and nylon-insert nuts. The guide does not print a separate bracket torque or a front/behind ordering like other vehicles.
Can the generic band torque be applied to all bolts?The selected guide prints a generic 40-45 ft-lb band-clamp setting, but the formal bill lists no separate band clamp and does not expressly assign that setting to the tip-fastener arrangement. Confirm correct tip-clamp applicability with aFe before applying it. It is not a flange-bolt, bracket-screw or universal fastener torque. Use correct separate settings, align then tighten front to rear, and retighten all clamps and hardware after 50-100 miles.
Does this include Turbo Ultimate or Veloster N?The exact-part named table supports Turbo Ultimate 2019-2021 as well as Turbo and Turbo R-Spec for the turbo 1.6L application. No 2.0L Veloster N approval is inferred.
Does the chart show a peak torque gain?The primary claims up to +8 hp/+8 lb-ft. At the linked chart marker of 5,341 rpm, axle-back versus baseline values are 181.10 versus 173.21 hp (+7.89 hp) and 184.18 versus 176.13 lb-ft (+8.05 lb-ft). Separate peak power differs by +6.40 hp (191.18 at 5,850 versus 184.78 at 5,800 rpm). Peak torque is LOWER by 7.91 lb-ft in the axle-back run: 221.24 at 3,810 versus 229.15 at 2,960 rpm. A positive marked-point difference is not a peak-torque gain. Both run notes specify aFe cold-air intake, stock wheels/tires, Sport mode, traction control off, fourth gear, 2,000-rpm start and blade fan; SAE 1.00 on February 19, 2020. Baseline is 1:14:20 PM versus axle-back 10:44:18 AM. The visible chart does not print selected production part number, finish or vehicle model year; no stock-intake or finish-specific guarantee is inferred.
