CTS Turbo race downpipe set for Mercedes Benz C43 AMG, C400, C450 AMG, E43 AMG, E400 and E450 AMG with M276 engine is made to maximize exhaust flow for highest power gains. Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance. In addition to unleashing the power and performance of your 3.0 Twin Turbo, our downpipes will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust "crackle" on downshift. While up-shifting you will enjoy a confident "punch!" as you bang through all the gears. The sound will be even louder if you already have an aftermarket exhaust system. Product Details:
  • 3" downpipes with heatshielding
  • Cast T304 stainless steel, TIG welded back-purged construction
  • Replaces restrictive factory catalytic converter
  • Fits within OEM heat shields
  • Great power upgrade with uncompromising performance
  • Incredible sporty exhaust sound, subtle when cruising
  • No drone with factory exhaust
  • Replaces OE numbers: 276-140-94-13  and 276-140-96-13 (check your vehicle to make sure you have the "short" factory catalytic converters)

Just wanted to share some love to Harry's euro and their team! Bought parts for my r32 and gti, they never disappoint. Love being part of the euro community in an ever so dominant jdm culture in New Zealand. Looking forward to bringing an rs3 in for tuning :)

I've been a loyal customer of Harry's Euro since 2017, and I can confidently say Scott and his team are the best in the game. Not only do they consistently offer the best prices, but the service is always top-notch. Scott is honest, transparent, and always takes the time to explain what’s going on with my car. Whether it's routine maintenance, unexpected repairs, or upgrades, I always know my car is in the best hands. Highly recommend to anyone looking for a reliable, expert mechanic!

Used Harry's Euro for years owning a Mk6R and now a Mk5 R32. Amazing service and delivery! R32 kit arrived today with some extra goodies! Pleasure to deal with the team!

Hands down the best Euro shop in Auckland. They've looked after 2 builds of mine, and the parts, service and expertise has been top notch.

Harry's Euros delivered platinum service from start to finish. The quality of the products is excellent, and the install experience was smooth and professional. If you want a lower cost acceleration boost ask Scott about a Pedal Box! Huge difference and very simple to use.

Got some basic servicing and a Stage 2 transmission tune done today to match the ECU tune. The team was really helpful with information, communication via email, fit me in quickly, and offered fair, industry standard pricing for a specialised shop. Highly recommend, and I'll definitely be back!

Great service. Needed a replacement driver's side mirror glass for our old GTI. Harry's Euro had it in stock for a good price and shipped it next day. Very pleased with the transaction and will happily recommend and use them again.

Been Working with Harry's Euro for almost 3 years now and I can highly recommend any auto-work or performance upgrades to be done by these guys. I've had my previous car and my current done by the team cheers to Scott and the boys for the work 🍻
