Product Description

Audi Performance Parts: 42 Draft Designs 3" Downpipe for Audi MK1 TT 225HP 1.8T Quattro (EXT125DP)

 

Product Features & Benefits

  • Unleashes the power that your turbocharger wants to deliver
  • Modification that is truly "that" simple
  • Normal hand tools can be used on all bolts
  • Horsepower and torque increases estimated at 15hp and 20ft/lbs

42 Draft Designs 3” downpipe is the single most effective bolt-on upgrade for the Audi TT 225. No other basic physical modification can compete with the power gains delivered by this fundamental upgrade. Simply by reducing backpressure creates useable horsepower and torque throughout the power band while also improving turbo spool and throttle response.

Street Series downpipes are equipped with a 200/cell high-flow catalytic converter. Race Series downpipes include only a test pipe for track day. Included adaptor reduces pipe size to utilize the OEM band clamp.

Additional Details

Fitment:

  • 1999-2006 Audi TT 225 1.8T Quattro
  • Included adaptor allows fitment to stock exhaust
  • Will fit any cat-back exhaust that reduces to stock diameter
  • Available in street or race configuration
  • This downpipe will NOT fit 180 FWD or 180 quattro TTs. The 225 exhaust layout is unique to the the 225. This downpipe will fit no other TT or VW. 180 FWD & Quattro downpipes are available.

Note: Model years listed are based on US models. European model years may differ. If shopping for a vehicle sold outside the US please match chassis designation before matching model year.

Polyurethane transmission mount inserts are HIGHLY recommended for this application.

Starting at the turbo discharge the downpipe bolts up with a CNC machined turbo flange. A tight radius bend smoothly sends exhausts gases downward, steering clear of critical engine bay components. Joined to this bend with precision TIG welds, CNC mandrel bent tubing and a flex section route exhaust gases through one of the tightest tunnels Audi makes. Piping clears all heatshields, the subframe, and driveshaft with ease. CNC machined adjustable flanges connect the cat section, tucking a Magnaflow 200 cell metal high-flow cat into the limited space available. After the cat, a series of mandrel bends route the downpipe to the factory cat-back, attached using an adaptor. This adaptor allows the fitment of stock exhaust and all aftermarket cat-backs.

Click here for Test Pipe Component only. The test pipe only is designed to work with this downpipe set up for those who wish to have both the cat-pipe and swap out for the test pipe at the track.

    this pipe will not last in pa winters, for the money it should be at least 409 grade stainless, may last a while in arizona. had 304 stainless on my last car 10 yrs and 199xxx miles NO sign of rust or any degrading, ceramic coating means little except more $$$$ from experience
