aFe Large Bore-HD Cat-Back - Volkswagen Jetta TDI 2.0L

Volkswagen Jetta TDI Large Bore-HD cat-back

The aFe 49-46401 cat-back uses two sections of 2.5-inch mandrel-bent 409 stainless tubing with welded hangers and a polished double-wall dual 3-inch outlet. The exact current application identifies 2011-2014 Jetta TDI diesel L4-2.0L. The older 2011-2012 guide lists 101.5-to-104.4-inch wheelbase and requires cutting for original-system removal.

Key Features

• Selected aFe part 49-46401.
• 2.5-inch mandrel-bent 409 stainless two-section system.
• Polished double-wall dual 3-inch outlet on the selected tailpipe.
• One 2.25-inch front band and one 2.5-inch mid/tail joining band.
• Original isolation mounts retained; no new rubber mounts are listed.
• Original-system removal cut required to clear rear axle; converter-side slip connection retained.

Fitment

The exact current manufacturer table identifies Jetta TDI diesel 2.0L. Existing generic 2011 Jetta Base data is positive in the retailer table but does not establish an exact US diesel named configuration; it remains UNVERIFIED legacy data requiring manufacturer confirmation. Do not read Base as approval for gasoline models. The selected guide states 101.5-to-104.4-inch wheelbase, without establishing a new SportWagen model mapping. US Volkswagen engine and equipment tables separate diesel TDI from gasoline Jetta S and GLI. The 2011-2014 S and 2012-2014 GLI mappings are removed from this diesel-only product despite retailer-positive rows. The 2012 US press kit explicitly identifies the GLI gasoline engine; 2013/2014 specification tables likewise separate GLI TSI from TDI diesel. No engine-size-only equivalence is used. The original approved diesel year bounds remain unchanged; no new named applications are added.

one mid-pipe 05-44372 and one tailpipe 05-44373, one 2.25-inch band 05-41210 and one 2.5-inch band 05-41061. The tailpipe carries a polished double-wall dual 3-inch outlet; no separate decorative tip or conventional muffler assembly is listed.

The selected Jetta guide requires cutting the original pipe to clear the rear axle during removal and explicitly says not to cut the pipe after the catalytic converter, because that slip connection is reused. No numeric cut distance is printed. Confirm the actual rear-axle removal cut before work; no Golf no-cut promise or Passat cut location is borrowed.

Selected step 5 says to tighten the turbo band clamp, but the sheet describes rear cat-back joints and gives no earlier turbo-access, disconnection or sensor work. This unexplained instruction needs aFe confirmation for the actual vehicle before work. No turbocharger, emissions-filter or sensor removal procedure is invented.

No numeric torque is printed. Keep all bands loose until installed and aligned, preserve the guide's at-least-1/2-to-1-inch tailpipe/body spacing and retighten all exhaust components after 50-100 miles.

No. No selected measured gain or weight result is established, and none is borrowed from Golf. This rear cat-back is not authorization to remove, disable or alter the original catalytic converter, diesel filter, sensors or controls.

Installation Instructions

1. Confirm aFe 49-46401 against the exact vehicle and installed equipment. Inventory the actual components and follow the selected manufacturer instructions and current vehicle service requirements.
2. Confirm exact diesel Jetta 2.0L, named range and actual body/wheelbase. Resolve any generic Base configuration before ordering. Obtain aFe clarification of the unexplained turbo-band step before work; use actual vehicle support requirements and allow the exhaust to cool.
3. Remove the original rear exhaust working from rear toward front. The selected Jetta guide requires cutting the original pipe to clear the rear axle during removal and explicitly says not to cut the pipe after the catalytic converter, because that slip connection is reused. No numeric cut distance is printed. Confirm the actual rear-axle removal cut before work; no Golf no-cut promise or Passat cut location is borrowed.
4. Install the selected mid-pipe using original isolation mounts and supplied 2.25-inch band. Install the selected over-axle/tailpipe using original mounts and supplied 2.5-inch band. Leave bands loose until the entire system is installed and aligned.
5. Selected step 5 says to tighten the turbo band clamp, but the sheet describes rear cat-back joints and gives no earlier turbo-access, disconnection or sensor work. This unexplained instruction needs aFe confirmation for the actual vehicle before work. No turbocharger, emissions-filter or sensor removal procedure is invented.
6. Align and secure the actual selected connections, maintain at-least-1/2-to-1-inch tailpipe/body spacing and recheck work. No numeric torque is printed. Retighten all exhaust components after 50-100 miles. No battery, sensor, chassis-brace or emissions-equipment service is borrowed.
