Product Description

Audi Performance Parts: 42 Draft Designs Audi TT 225HP Quattro 3" Downpipe (EX-TT-105)

42 Draft Designs Audi TT 225HP Quattro 3" Downpipe is designed specifically for Audi TT MK1 '00-'06' models. Downpipes upgrades have proven to be worthwhile modifications for all 1.8T engines. Equipped with a K04 turbocharger and quattro drivetrain, the TT 225 is ready to put down all the power the K04 can deliver. Although well equipped, the TT's power potential is held back by restrictive factory components. Unleash that power with a 3" downpipe upgrade! Most would agree that no modification is that simple. Since the TT first hit the US, tuners and enthusiasts have claimed 3" exhaust would not fit the quattro TT due to the narrow and awkwardly shaped exhaust tunnel. Fitment is tight, but certainly not impossible. In 2006, 42 Draft Designs released the 3" downpipe for the 225 quattro, changing the attitudes of countless TT owners. We make it that simple, building a downpipe that fits within demanding constraints and provides horsepower and torque gains worthy of the TT badge.

 

Product Features & Benefits

  • Unleashes the power that your K04 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

 

Additional Details

Starting at the turbo discharge our 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 we've ever worked with. Piping clears all heatshields, the subframe, and driveshaft with ease. CNC machined adjustable flanges connect our 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 a 2.55" adaptor. This adaptor allows the fitment of stock exhaust and all aftermarket cat-backs. Additional adaptors are available for 2.75" and 3" cat-backs.

From turbo to cat-back the fitment of our downpipe has been fine tuned to perfection. The TT engine bay, body, and quattro drivetrain leave almost no space for a downpipe of this size. Our downpipe considers every fitment detail without over-complicating the modification. The first bend exiting the turbo has been positioned so that normal hand tools can be used on all bolts. Piping route and flex section position favor clearances and product longevity. Adjustable flanges allow the cat section and test pipe to be adjusted for maximum heatshield clearance without rattles. Oxygen sensor bung locations allow for simple installation in tight spaces. Wiring harness lengths are not affected and fitment is compatible with LHD & RHD TTs.

Serious by design, our 3" downpipe squeezes all available power from a street or track driven TT. Horsepower and torque increases are estimated at 15hp and 20ft/lbs at the wheels, supported by additional modifications. Power increases can be felt instantly after installation. Midrange and top end power increases dramatically while almost no low end power loss is felt. Boost builds steadily without a major spike in pressure. The one and only side effect of our 3" downpipe is fun!

In April of 2007 Joe Lucchio of Fourtitude/VWVortex put this downpipe to the test. With his existing modifications the dyno showed 9.3 hp and 19.3 ft/ lbs peak gains at the wheels. Gains were proven throughout the RPM range and drivability was greatly improved.

  1. overpriced cheap mild steel

    Posted by Unknown on 28th Nov 2012

    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
